The content delivery network (Content Delivery Network, CDN) is an intelligent virtual network built on the basis of the existing network, and provides acceleration service for resources accessed by users by virtue of edge servers deployed in various places, so that the users can acquire required content nearby. The acceleration service for the resources is realized by means of configuration information of each resource deployed in the CDN network, and the configuration information includes, for example, a domain name, a service type, an acceleration area, acceleration content, an operator, and the like, which need acceleration.
With the increase of network nodes, configuration information to be deployed is also increased, and if detailed configuration information is to be deployed for each server, considerable manpower and material resources are consumed. At the same time, if the configuration information needs to be updated, the amount of data that needs to be processed is also quite large. Thus, there is a need for a more efficient deployment of configuration information.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below in conjunction with the detailed description of the present application and the corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to fall within the scope of the present application.
The application provides a deployment method of configuration information, which can be applied to a configuration platform. Referring to fig. 1, the method may include the following steps.
S1: and reading target configuration information, wherein part or all configuration items in the target configuration information are inherited from the inherited configuration information.
In this embodiment, the domain name configuration is illustrated in the CDN network, for example, when the configuration information is domain name configuration information, the configuration platform may deploy the domain name configuration information to the edge server according to the method, so that the edge server provides an acceleration service for each domain name according to the configuration information corresponding to each domain name. Corresponding configuration information can be deployed in the edge server aiming at different application scenes. For example, for a domain name resolution scenario, configuration information for performing domain name resolution may be deployed. For another example, for a resource scheduling scenario, configuration information for performing resource scheduling may be deployed. In the configuration information, a plurality of different configuration items may be included.
In this embodiment, the configuration items in the configuration information may be represented in different manners according to the functions to be implemented. For example, the configuration items may include matching conditions, filtering operators, available judgment operators, priority operators, selection operators, and the like. Wherein, the matching condition can be represented by M, the screening operator can be represented by C, the judging operator can be represented by A, the priority operator can be represented by P, and the selecting operator can be represented by S. The filtering operator, the judging operator, the priority operator and the selecting operator can be collectively called as an execution strategy, so that the matching condition and the execution strategy can form an MCAPS record, and a plurality of MCAPS records can be included in the configuration information.
Taking the scenario of domain name resolution as an example, for a target domain name, the configuration information may be as shown in fig. 2. In this configuration information, four MCAPS records may be included. Wherein the matching condition in each MCAPS record may comprise at least one of a geographical location (region), an autonomous domain (autonomous system, as), an operator (isppgroup). For example, in the first MCAPS record, the geographical location and the operator's restrictions may be included, while in the second through fourth MCAPS records, only the geographical location restrictions may be included. Of course, in practical applications, the MCAPS record may not include any constraint, in which case, the MCAPS record may serve any IP address field where the client is located or the IP address of the recursive server.
In practical applications, to simplify the deployment process of the configuration information, the configuration information to be deployed may be inherited from the inherited configuration information. Wherein part of the content or the whole content of the configuration item can be selectively inherited. For example, in an application scenario, in the configuration information of the edge server, the filtering operator may inherit from the inherited configuration information, while other configuration items may not inherit. This flexible inheritance approach makes it possible that only a portion of the same configuration items exist in the configuration information in the edge server as in the inherited configuration information.
In carrying out inheritance of the configuration information, in the configuration information of the edge server, an information identifier of the inherited configuration information may be carried, where the information identifier is used to characterize an identity of the inherited configuration information, for example, when the inherited configuration information is a domain name, the information identifier may be a domain name identifier. For example, most domain names may have basic configuration information, while some domain names may have adjustments to the basic configuration information for some particular regions. In view of this, a domain name final configuration information may be generated by inheritance.
Specifically, referring to fig. 3, when configuration information is set for a target domain name, the configuration information of the target domain name includes at least one domain name identifier of an inherited domain name; the domain name identification points to configuration information of the inherited domain name.
For example, in the configuration information of the target domain name, the following may be used: in this manner, xxx.com ", reference is made to inherited domain names. Where xxx.com is the domain name identity of the inherited domain name, parent may represent xxx.com as the inherited domain name. The actual configuration information of the inherited domain name can be queried upwards through the domain name identification of the inherited domain name. Of course, the configuration information of the inherited domain name may still include the domain name identifier of the inherited domain name of the previous level. By means of the layer-by-layer upward query mode, detailed configuration information can be queried finally. The domain name identifier may be an information identifier of inherited configuration information.
In practical applications, when setting configuration information for a target domain name, initial configuration information may be set first, and the domain name may select whether to inherit the configuration information from another domain name (inherited domain name). If the configuration information can be inherited from the inherited domain name, when the policy element is missing in the configuration information of a certain target domain name, the missing policy element can be inherited from the configuration information corresponding to the inherited domain name in the policy inheritance relationship. The policy element may be any element in MCAPS. When inheriting the missing policy element from the inherited domain name, a conflict may occur with other policy elements that exist themselves. In this case, the conflicting policy elements may be processed in a preset manner. For example, the filter operator C may collide, in which case, if the policy element inherited is a filter operator, the filter operator in the configuration information of the inherited domain name is reloaded (override) as the filter operator in the configuration information of the target domain name. Of course, depending on the application scenario, when the policy element is inherited, the methods of intersection (intersection), union (unit) and the like may be adopted, and are not limited to the heavy load method.
In one embodiment, if the missing policy element does not exist in the configuration information corresponding to the inherited domain name, the missing policy element may be inherited from a global default rule. By means of the step-by-step upward inheritance mode, it can be ensured that all required policy elements can be obtained from the configuration information of the domain name.
After inheriting the content of the configuration item from the inherited configuration information to form new configuration information, if some personalized settings need to be performed on the new configuration information, the corresponding configuration item can be directly added or modified in the new configuration information, and the inherited configuration information is not affected in the process, so that the customization and personalized configuration of the configuration information are increased. In addition, if the content in the inherited configuration information is changed, for example, some configuration items in the inherited configuration information are optimized, and the changed content is inherited into new configuration information, then the changed content in the new configuration information is changed accordingly, so if a plurality of configuration information with inherited relationships are required to be uniformly changed, only the content of the inherited configuration information is required to be changed, the changed content can be effective for the configuration items in other configuration information with inherited relationships according to the inherited relationships, the configuration information of inheritors is not required to be changed one by one, the complexity of configuration information deployment is simplified, and the deployment efficiency is improved.
S3: respectively generating color block identifiers corresponding to each configuration item in the target configuration information, and displaying the corresponding color block identifiers at the configuration items in the target configuration information; for any target configuration item in the target configuration information, if the color block identifier of the target configuration item is consistent with the color block identifier at the corresponding position in the inherited configuration information, the target configuration item in the target configuration information is characterized to be completely inherited from the inherited configuration information.
In this embodiment, in order to identify whether the content of the configuration item in the target configuration information is consistent with the content of the configuration item in the inherited configuration information, the color patch identifications corresponding to the configuration items in the target configuration information may be generated respectively, and similarly, the color patch identifications corresponding to the configuration items in the inherited configuration information may be generated respectively in the same manner.
Specifically, each configuration item corresponds to an actual configuration string, and the configuration string can define information such as functions adopted by the configuration item, parameters corresponding to the configuration item, and the like. The configuration string may be converted to a corresponding hash string by a hashing algorithm. For example, the MD5 value of the configuration string may be calculated. After the hash character string is obtained, the hash character string can be divided into a specified number of fields, and each field is respectively converted into different components in the color block identifier so as to form the color block identifier corresponding to the configuration item.
For example, a hash string may be represented as 6efc736f308149 eedb2 bc1f8c230042, which may be divided into six fields, respectively: 6efc73, 6f3081, 49eeda, b2bc1f, 8c2300, and 42, which can be converted into different components in the color patch identification, respectively.
In practical applications, the color block mark may be represented in the manner shown in fig. 4, and in the color block mark, the following six components may be included:
a background color of the first region;
a background color of the second region;
a first text filled in the first area and a second text filled in the second area;
the color of the first text;
the color of the second text;
line color for defining the outer contour of the first and second regions.
In fig. 4, the left rectangle may be a first region, the right rectangle may be a second region, the background color of the first region may be determined by 6efc73, and the color of the first text within the first region may be determined by 6f 3081. The background color of the second region may be determined by 49eeda and the color of the second text within the second region may be determined by b2bc1 f. The line color of the outer contour line (thicker rectangular line) can be determined by 8c 2300. The first text may be 4 and the second text may be 2.
Thus, in the manner described above, the hash string may ultimately be characterized by the color patch identification. For each configuration item, the representation may be made in this way. In addition, for the whole configuration information, a color block identifier of the whole configuration information can be generated in such a way that the whole color block identifier is generated for the target configuration information, and if the whole color block identifier of the target configuration information is consistent with the whole color block identifier of the inherited configuration information, the target configuration information is characterized to be completely inherited from the inherited configuration information.
Subsequently, by comparing the color block identifiers of the configuration items one by one, whether the contents of the two configuration items are consistent can be determined. And if the color block identification of the target configuration item is consistent with the color block identification at the corresponding position in the inherited configuration information, the target configuration item in the target configuration information is characterized to be completely inherited from the inherited configuration information. Correspondingly, if any component in the color block identifier of the target configuration item is inconsistent with the corresponding component of the color block identifier of the corresponding configuration item in the inherited configuration information, the target configuration item in the target configuration information is characterized as being different from the corresponding configuration item inherited from the inherited configuration information.
For example, fig. 5 and 6 show color block identifiers of a corresponding configuration item filter operator (candidate), an available judgment operator (available), and a priority operator (priority) in the inherited configuration information and the target configuration information, respectively, and by comparing color block identifiers of respective operators of the same configuration item in the inherited configuration information and the target configuration information, it can be judged that the filter operator of the target configuration information is not completely inherited from the inherited configuration information, that is, the configuration item "filter operator" of the target configuration information is different from the configuration item "filter operator" of the inherited configuration information, and the configuration item "available judgment operator" of the target configuration information "and the priority operator" are all completely inherited from the configuration item corresponding to the inherited configuration information.
In one embodiment, the configuration string of the configuration item is typically represented in JSON format, which typically includes multiple sets of key-value pairs. Since the arrangement order of the key value pairs in the configuration string is not explicitly specified, the calculated hash strings may be different due to the different arrangement order of the key value pairs. For example, the configuration string of the inherited configuration information is { "a":20, "b":30}, and the configuration string of the target configuration information is { "b":30, "a":20}, which are identical in practice, except that the calculated hash strings are different due to the different arrangement order of key value pairs, and thus the generated color patch identifications are also different.
In view of this, in the present embodiment, it is necessary to format the configuration string before calculating the hash string, and unify the arrangement order of key value pairs therein. Specifically, the arrangement order of keys may be set in advance. For example, the keys may be arranged in an order from a to z, and then for the configuration string { "b":30, "a":20}, as described above, the configuration string { "a":20, "b":30}, may be ordered in the order of the pre-specified keys to generate a formatted configuration string { "a":20 }. By the ordering mode, configuration character strings with consistent contents can be ensured, and after formatting is carried out, the calculated hash character strings are consistent, so that misjudgment is avoided.
It can be seen that a plurality of different configuration items can be included in the configuration information, and in order to measure whether each configuration item is the same, the characteristics of the configuration items can be visually represented by adopting a color block identification mode. Specifically, the color block identifier of the configuration item can be displayed at the configuration item, so that whether the configuration item is consistent in the target configuration information and the inherited configuration information can be quickly identified by comparing the color block identifiers of the same configuration item in the target configuration information and the inherited configuration information. In the deployment process of the configuration information, the comparison of the configuration information is converted into the comparison of the color block identifiers, so that the deployment process of the configuration information can be greatly simplified, the update efficiency of the configuration information is further improved, and the edge server can be ensured to provide services stably.
Based on the inheritance mode of the configuration information and the characterization mode of the color block identification, whether the configuration items with identical contents exist in the two configuration information can be rapidly determined under the condition of simplifying the configuration information deployment difficulty, so that an efficient basis is provided for subsequent configuration information updating.
In a specific application example, the configuration information of the accelerated domain name may be deployed in the edge server in the manner described above, and domain name resolution may be performed based on the deployed configuration information.
In this embodiment, the domain name resolution server may configure corresponding configuration information for the target domain name according to the foregoing manner, so that after receiving the domain name resolution request, the domain name resolution server may identify the configuration information corresponding to the domain name to be resolved according to the domain name to be resolved included in the domain name resolution request. In the configuration information, each constraint within the matching condition may correspond to a set of IP addresses. For example, for a defined condition of a geographic location, it is the set of individual IP addresses that are located within the geographic location that corresponds. One or more limiting conditions in the matching conditions can correspond to one or more IP address sets, and the IP address set corresponding to the intersection of the limiting conditions can be used as the IP address set limited by the matching conditions. For example, in fig. 7, the set of IP addresses in the shaded portion of fig. 7 can be obtained from the intersection of three constraints, geographic location, autonomous domain, and operator.
The set of IP addresses defined by the matching condition may be used as a reference basis for whether the matching condition is applicable to the current domain name resolution request. Specifically, if the domain name resolution request includes an IP address field where the client is located, and the IP address field where the client is located in the IP address set defined by the matching condition, then the matching condition is indicated to be applicable to the current domain name resolution request. For another example, if the IP address of the recursive server is in the set of IP addresses defined by the matching condition, the matching condition is also indicated to be applicable to the current domain name resolution request, provided that the domain name resolution request does not carry the IP address segment where the client is located, but carries the IP address of the recursive server in the domain name resolution process.
In the configuration information, each piece of MCAPS record may have a certain arrangement sequence, and when judging a matching condition applicable to the domain name resolution request, it may sequentially judge whether the IP address of the recursive server or the IP address field where the client is located in the IP address set defined by the current matching condition according to the arrangement sequence. If the matching condition is located, the current matching condition can be used as a target matching condition matched with the domain name resolution request.
For example, in fig. 2, the domain name resolution request carries the IP address of the recursive server, which is located in the Xiamen and which is served by the telecommunications. Thus, the domain name resolution request hits the first MCAPS record, and the matching condition in the first MCAPS record is the matching condition for the adaptation.
In this embodiment, after determining the target matching condition adapted to the domain name resolution request, a corresponding resource node may be allocated to the domain name resolution request according to the target execution policy bound to the target matching condition.
Specifically, the target execution policy may include four operators, such as CAPS, where each operator may undergo respective processing, so as to finally obtain which resource node should be fed back to the domain name resolution request.
Wherein, the filtering operator C (candidate) can generate a candidate list according to the matching condition, and the candidate list comprises candidate resource nodes determined from a resource node pool. A plurality of defined conditions in the matching conditions may be passed to the screening operator by an expression. In this expression, two kinds of arithmetic logic of "or" and "may be included. Different arithmetic logic may be represented in different forms. For example, a particular expression may be expressed as:
[[“sr:as.xm”,“sr:as.tw”],[“app:cs”]]
where sr: as.xm may define the geographical location "Xiamen" and sr: as.tw may define the geographical location "taiwan", the two geographical locations being located in the same bracket, and the bracket being the bracket of the innermost layer, the selection relationship between the two geographical locations may be "or". app:cs denotes a cache server. It can be seen that the innermost brackets define the geographic location and server type, respectively, and that the brackets in the two groups may be in an "and" relationship. That is, by the above expression, it is necessary to screen out the cache server located in Xiamen or Taiwan.
In this embodiment, each resource node may have a tag (tag) corresponding to itself, where the tag may represent a geographic location where the resource node is located, an operator supported by the resource node, a server type corresponding to the resource node, and so on. By comparing the above expression with the labels of the respective resource nodes, resource nodes conforming to the above expression can be screened out.
In practical applications, the expression may also have more forms, for example, a "no" expression may be adopted. By marking the condition with a label of "" to "", it can be shown that other resource nodes except the resource node defined by the condition can be used as the resource node for providing service. For example, an expression with a "-" label may be expressed as:
[[“～sr:as.cn.fj.xm”,“sr:as.cn.fj”],[“app:cs”]]
the expression represents a cache server (app: cs) of other fowls provinces (cn.fj) except for the Xiamen (cn.fj.xm).
It can be seen that, based on the screening operator, a candidate list can be generated in which candidate resource nodes determined from a pool of resource nodes can be included. The candidate list obtained in the above example includes resource nodes of cache servers in Xiamen or Taiwan.
In this embodiment, after determining candidate resource nodes based on the filtering operator, whether each candidate resource node is Available may be determined according to the Available determining operator a (Available). In particular, the availability judgment operator may identify producers associated with a candidate resource node and, in the event that each of the producers is available, judge that the candidate resource node is available. The producer associated with the candidate resource node may refer to a router/switch connected to the candidate resource node, a machine room where the candidate resource node is located, an access point cluster where the candidate resource node is located, and so on. To ensure availability of a candidate resource node, it may be determined that the candidate resource node is available when both of these associated producers are available.
In this embodiment, after determining available candidate resource nodes, the Priority of each candidate resource node may be determined according to a Priority operator P (Priority), so that one of the available candidate resource nodes is allocated to the domain name resolution request based on the determined Priority.
In practical applications, the domain name resolution request may carry an IP address field where the client is located, or may not carry an IP address field where the client is located, but carries an IP address of a recursive server that is in communication with the client. Based on different IP addresses, clusters of different candidate resource nodes may be obtained. For example, for a domain name resolution request carrying an IP address of a client, an available candidate resource node may be obtained through accurate node probing, or a matching candidate resource node may be obtained only through identification of a geographic location. The manner of accurate node detection can be recorded as PROBE, and the manner of geographic location based identification can be recorded as GEO. Thus, two different node screening modes, namely ECS-PROBE and ECS-GEO, can be provided for the IP address field (marked as ECS) where the client is located. Similarly, for the IP address of the recursive server (denoted as LIP), there are two different node screening approaches, LIP-PROBE and LIP-GEO. In general, the accuracy of the resource nodes obtained based on the client IP address and the accurate probing method is obviously higher, so the priority of the four node screening methods from high to low can be expressed as: ECS-PROBE > LIP-PROBE > ECS-GEO > LIP-GEO.
The above priority is adopted for different candidate resource nodes, and the confidence level of different screening modes can be combined to comprehensively measure. That is, a screening manner of each of the candidate resource nodes may be determined and a confidence level of the screening manner may be identified to set a priority of the candidate resource node based on the confidence level and the screening manner.
Specifically, if the candidate resource node is obtained by screening based on the IP address field where the client is located and the current confidence level meets the preset condition, the candidate resource node may be classified into the first priority.
And if the candidate resource node is obtained based on the screening of the IP address of the recursion server and the current confidence coefficient meets the preset condition, the candidate resource node can be divided into a second priority.
When the two priorities are not satisfied, whether the candidate resource node is obtained by screening based on the IP address field where the client is located can be judged, if so, the candidate resource node can be classified into a third priority, and if the IP address field where the client is located has a corresponding geographic position label.
If the candidate resource node is obtained based on the filtering of the IP address of the recursive server, and the IP address of the recursive server has a corresponding geographic location tag, the candidate resource node may be classified into the fourth priority.
If none of the above cases belong, the candidate resource node may be classified as a fifth priority.
For different candidate resource nodes, the priority operator P may perform the above processing, so as to determine the priority of the candidate resource node.
In one embodiment, the confidence level of the above screening method may be determined by:
and aiming at the IP addresses defined by the screening mode, if the number of the effectively detected access points reaches a specified number threshold, judging that the screening mode is credible.
The meaning of effective detection may mean that the detection time of the access point is not expired, wherein the expiration time may be 6 hours, and may be flexibly set in practical application, for example, may be 24 hours. The number threshold may be flexibly set according to actual requirements, for example, may be set to 14.
In addition, for the IP address defined by the screening mode, if a specified number of access points exist, and the detection method of each access point is in a preset list, the screening mode is determined to be credible.
The specified number of access points may be the top three access points, and the probing methods in the preset list may be, for example, ICMP probing methods and UDP probing methods.
In addition, for the IP address defined by the screening mode, if the detection result is in a preset range, the screening mode is determined to be credible.
The detection result may be an RTT (Round-Trip Time) value, and the preset range may be, for example, 0 to 2000ms.
In practical application, when the above three conditions meet one of them, the screening mode may be considered as trusted, and of course, when all the above three conditions are met, the screening mode may be considered as trusted, which is not limited in the present application.
In this embodiment, after determining the priority of each candidate resource node by the priority operator P, the IP address of the target resource node fed back to the client may be determined by the selection operator S (selection). In practical application, the selection operator S may take the candidate resource node with the highest priority as the feedback target resource node, and if there are multiple candidate resource nodes with the highest priority, the candidate resource node with the best performance and the most idle may be screened out according to the load balancing policy. After the target resource node is determined, the domain name resolution device can feed back the IP address of the target resource node to the client, and the client can initiate resource access to the target resource node.
In one embodiment, the same domain name is considered, and may be configured according to different network types (e.g., IPv4 and IPv 6). The supported candidate resource nodes may also be different for different network types. In view of this, different configuration information may be generated for the domain name for different network types. After receiving the domain name resolution request for the domain name, the network type corresponding to the domain name resolution request can be judged, so that the corresponding configuration information can be selected for screening the resource nodes.
It should be noted that, in this embodiment, the configuration information deployed in the edge server is a combination of the matching condition and the execution policy, and is not an optional IP address deployed directly. Therefore, even if the optional IP address is changed, the configuration information in the edge server will not change as long as the matching conditions and execution policy for screening the IP address are not changed. Therefore, even if the resource nodes in the network change frequently, the configuration information of the edge server cannot change accordingly, so that the complexity of configuration management is greatly improved, and the scheduling flexibility is improved.
In this specific application example, configuration information may be configured for the domain name in advance, and the configuration information may include matching conditions and corresponding execution policies. The domain name resolution request can be compared with each matching condition, so that the matched target matching condition is determined. The target execution policy with the target matching condition bound may screen out the resource nodes that are suitable for the domain name resolution request from among the plurality of resource nodes. By providing the IP address of the resource node to the client that initiated the domain name resolution request, the domain name resolution process can be completed. Therefore, through the mode, the appropriate resource nodes can be automatically screened out based on the configuration information of the domain name.
