Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The first embodiment:
as shown in fig. 1, a flowchart of steps of a method for managing and controlling network resource configuration in a first embodiment of the present invention is applied to a first control device, and the first control device is connected to a network management system NMS or a software defined network SDN controller included in a whole network, where an NMS or SDN controller connected to the first control device is a first control device, and another one of the NMS and the SDN controller, which is outside the first control device, is a second control device. Thus, when the first control device is connected with the NMS, the NMS is a first control device, and the SDN controller is a second control device; when the first control device is connected with the SDN controller, the SDN controller is a first control device, and the NMS is a second control device.
Specifically, the management and control method comprises the following steps:
in this step, specifically, the first control device is connected to the first control device, and the first control device can obtain the first resource requirement information sent by the first control device in real time. Specifically, assuming that the NMS connected to the first control device is a first control device and the SDN controller is a second control device, the first control device obtains first resource requirement information of the NMS at this time. In addition, the resource requirement information may be sent to the first control device when the NMS starts or opens a service.
And step 102, sending resource configuration information of available resources in the whole network resources to the first control equipment according to the first resource demand information.
In this step, specifically, when the first control device obtains the first resource requirement information of the first control device, the resource configuration information of the available resources in the entire network resources may be sent to the first control device according to the first resource requirement information.
In this way, the first control device only sends the resource configuration information of the available resources in the resources of the whole network to the first control device, so that the first control device can only check and access the resource configuration information of the available resources, and cannot check and access the resource configuration information of the unavailable resources, thereby avoiding the conflict with the resources managed by the second control device; in addition, because the first control device can only obtain the resource configuration information of the available resources, the first control device can only use the resource configuration information of the available resources to open the service, thereby ensuring that the service corresponding to the first control device and the configuration of each network device in the whole network are compatible, and ensuring that the first control device does not influence the opened services of other control devices when the configuration resources are adjusted.
The first control device in this embodiment is connected to an NMS or SDN controller included in the entire network, wherein the NMS or SDN controller connected with the first control device can be used as a first control device, the other one of the NMS or SDN controller except the first control device can be used as a second control device, thus, the first control device sends the resource configuration information of the available resources in the whole network resources to the first control equipment according to the first resource demand information of the first control equipment, so that the first control device can only acquire the resource configuration information of the available resources, but cannot acquire the resource configuration information of the unavailable resources in the whole network resources, so that the first control device can only manage resources using the resource configuration information of available resources, the interference on the unavailable resources can not be carried out, so that the conflict between the first control equipment and the resources managed by the second control equipment when the resources are managed by the first control equipment is avoided; in addition, because the first control device can only obtain the resource configuration information of the available resources, the first control device can only open the service by using the resource configuration information of the available resources, and the service corresponding to the NMS and the SDN controller and the configuration of each device in the network are both ensured.
Further, when the resource configuration information of the available resources in the entire network resources is sent to the first control device according to the first resource demand information, the following method may be included:
the first method is as follows:
further, when the resource configuration information of the available resources in the entire network resources is sent to the first control device according to the first resource requirement information, the resource configuration information of the pre-divided resources in the entire network resources may be sent to the first control device according to the first resource requirement information, where the available resources of the first control device include the pre-divided resources. Of course, specifically, the pre-divided resource is a resource pre-divided to the first control device, and the resource pre-divided to the first control device is not overlapped with the resource pre-divided to the second control device. Specifically, the first control device may be provided in the first control apparatus, or may be provided outside the first control apparatus.
In the first embodiment, the whole network resources include resources pre-partitioned to the first control device and resources pre-partitioned to the second control device, and the resources pre-partitioned to the first control device are not overlapped with the resources pre-partitioned to the second control device, that is, the whole network resources are pre-partitioned into resources available to the first control device and resources available to the second control device, and the first control device can only view and access the available resources pre-partitioned to the first control device, but cannot view and access the available resources pre-partitioned to the second control device. Therefore, the management resources of the first control device can not conflict with the management resources of the second control device, and the service corresponding to the first control device and the configuration of each network device in the network can be ensured to be compatible.
This is explained in detail below with reference to fig. 2.
Fig. 2 is a schematic diagram illustrating relationships between NMS and SDN controllers and resources on the whole network in the first mode. It is assumed that the NMS connected to the first control device is a first control device and the SDN controller is a second control device. At the moment, the first control device divides available resources for the NMS, the second control device divides available resources for the SDN controller, and the available resources divided to the NMS in advance are not overlapped with the available resources divided to the SDN controller in advance. Specifically, for example, if fei-0/1 ports of an a device in the whole network are available resources pre-partitioned to the NMS, fei-0/1 ports of the a device are not visible on the SDN controller, that is, the SDN controller cannot view and access the fei-0/1 ports. For example, a tunnel-id in the whole network is an available resource pre-divided to the NMS in 10000-. Of course, when pre-partitioning the resources available to the NMS, it may be checked whether the services already existing on the NMS correspond to the pre-partitioned resources available to the NMS, and if not, the resources available to the NMS may be re-partitioned so that the services already existing on the NMS correspond to the pre-partitioned resources available to the NMS.
The second method comprises the following steps:
further, when the resource configuration information of the available resources in the whole network resources is sent to the first control device according to the first resource demand information, the resource configuration information of the resources occupied by the second control device in the whole network resources, which is sent by the second control device, can also be received, and the second control device is connected with the second control device; then according to the first resource demand information and the received resource configuration information of the resources occupied by the second control equipment in the whole network resources, sending the resource configuration information of the resources not occupied by the second control equipment to the first control equipment; wherein the available resources of the first control device include unoccupied resources of the second control device.
In the second embodiment, the second control device is connected to the second control device, and the first control device and the second control device can communicate with each other. Of course, the second control device may be provided in the second control apparatus or may be provided outside the second control apparatus. In this way, the first control device obtains the resource configuration information of the unoccupied resource of the second control device according to the received resource configuration information of the resource occupied by the second control device in the whole network resource, and sends the resource configuration information of the unoccupied resource of the second control device to the first control device. According to the method, through the communication between the first control device and the second control device, the unoccupied resources of the second control device are used as the available resources of the first control device, the utilization rate of the resources in the whole network can be improved, and the waste of the resources in the whole network is reduced. In addition, resources which are not occupied by the second control equipment are used as available resources of the first control equipment, so that the resource range of the available resources which can be selected by the first control equipment when the service is opened is increased, and the success rate of opening the service is improved. In addition, the first control device can only receive the resource configuration information of the unoccupied resource of the second control device, so that the first control device can only perform resource management on the unoccupied resource of the second control device, and cannot check and access the occupied resource of the second control device, thereby avoiding the conflict between the first control device and the occupied resource of the second control device when managing the resource, and the first control device can not delete or modify and adjust the service which has been opened by the second control device by mistake when opening the service, thereby ensuring that the service corresponding to the first control device and the second control device and the configuration of each device in the network have the same function.
Specifically, when receiving resource configuration information of resources occupied by the second control device in the whole network resources, which is sent by the second control device, the first control device may first divide the first control device and the second control device into a main control device and a standby control device. Preferably, the main control device and the standby control device may be distinguished according to the start time of the first control device and the start time of the second control device, where when the start time of the first control device is earlier than the start time of the second control device, the first control device is the main control device, and at this time, the first control device may receive resource configuration information of resources occupied by the second control device in the whole network resources, which is sent by the second control device in real time; when the starting time of the first control device is later than the starting time of the second control device, the first control device is a standby control device, and at this time, the first control device may first send an inquiry message for inquiring resource configuration information of resources occupied by the second control device in the entire network resources to the second control device, and then receive the resource configuration information of the resources occupied by the second control device in the entire network resources, which is sent by the second control device according to the inquiry message.
This is explained in detail below with reference to fig. 3.
Fig. 3 is a schematic diagram illustrating the relationship between the NMS and SDN controllers and the resources of the whole network in the second mode. It is assumed that an NMS connected to a first control apparatus is a first control device, an SDN controller connected to a second control apparatus is a second control device, and communication is enabled between the first control apparatus and the second control apparatus. When the starting time of the first control device is earlier than that of the second control device, the first control device is a main control device, and the second control device is a standby control device. Specifically, when the SDN controller opens a service, that is, when there is a resource demand, the second control device sends, to the first control device, a query message for querying resource configuration information of resources occupied by the NMS in the resources of the entire network, so as to obtain the resource configuration information of the resources not occupied by the NMS, and use the resources not occupied by the NMS as available resources of the SDN controller. Of course, when the SDN controller opens the service, the second control device may also send, according to the resource configuration information required for service opening, a query message for querying whether the NMS occupies the resource configuration required for service opening to the first control device, and receive a feedback message for querying whether the resource configuration required for service opening, which is fed back by the first control device, is an available resource. At this time, if the resources required by service provisioning are configured as available resources, service provisioning can be performed; if the resource configuration required by the service fulfillment is unavailable, an error is reported, namely the service cannot be fulfilled because the resource cannot be acquired. Therefore, when the SDN controller opens the service, the service can be opened by using the available resources of the SDN controller, and at the moment, if the SDN controller fails to open the service, the occupied resources when the service is opened need to be released, so that the proportion of the unoccupied resources in the resources of the whole network is increased, and the utilization rate of the resources of the whole network is improved.
The third method comprises the following steps:
further, in this mode three, the first control apparatus may be further connected to the second control device, and at this time, when sending resource configuration information of available resources in the entire network resources to the first control device according to the first resource demand information, may receive resource configuration information of resources occupied by the second control device in the entire network resources, which is reported in real time by the second control device, and then send resource configuration information of resources not occupied by the second control device to the first control device according to the first resource demand information and the received resource configuration information of resources occupied by the second control device in the entire network resources; wherein the available resources of the first control device include unoccupied resources of the second control device.
In the third embodiment, the first control device is connected to the first control device and the second control device at the same time, and both the first control device and the second control device can communicate with the first control device. In this way, the first control device can directly acquire the resource configuration information of the resources occupied by the second control device in the whole network resources, so as to acquire the resource configuration information of the resources not occupied by the second control device. According to the method, the whole network resources are uniformly managed through the first control device, and when the first control device has a resource demand, the resource configuration information of the resources which are not occupied by the second control device in the whole network resources is sent to the first control device, so that the convenience of whole network resource management is improved. In addition, the first control device sends the resource configuration information of the resources which are not occupied by the second control equipment in the resources of the whole network to the first control equipment, so that the resource range of available resources which can be selected by the first control equipment when the service is opened is increased, and the success rate of opening the service is improved. In addition, the first control device can only receive the resource configuration information of the resources not occupied by the second control device, so that the conflict between the first control device and the resources occupied by the second control device when the resources are managed is avoided, the service opened by the second control device cannot be deleted or modified and adjusted by mistake when the service is opened by the first control device, and the service corresponding to the first control device and the second control device and the configuration of each device in the network are ensured to be both.
This is explained in detail below with reference to fig. 4.
Fig. 4 is a schematic diagram illustrating relationships between NMS and SDN controllers and resources on the whole network in the third embodiment.
Assuming that the NMS is a first control device, the SDN controller is a second control device, the first control device is simultaneously connected with the NMS and the SDN controller, and both the NMS and the SDN controller can communicate with the first control device. Specifically, when a service (e.g., an L2VPN service such as mspw) is provisioned through an SDN controller, the SDN controller may send first resource requirement information to a first control device, and then receive resource configuration information of resources that are not occupied by NMS and sent by the first control device according to the first resource requirement information, that is, resource configuration information of resources available to the SDN controller, at this time, if the resources available to the SDN controller include resources required to provision the service, service provisioning may be performed, and if the service provisioning fails at this time, the resources required to provision the service need to be released; if the available resources of the SDN controller do not include the resources required for opening the service, the service cannot be opened. In addition, specifically, the first control device is used as a core device for managing resources of the entire network, and reliability of the first control device (supporting a high-availability cluster), such as supporting a main standby device, needs to be ensured. When the first control device is restarted, the data stored in the first control device needs to be restored, and the data needs to be fished and refreshed from the first control device and the second control device.
In this embodiment, through the above three ways, resource configuration information of available resources in the entire network resources is sent to the first control device, so that the first control device can only manage the resources by using the resource configuration information of the available resources, and cannot interfere with unavailable resources, so that the first control device does not conflict with resources managed or occupied by other control devices when managing the resources; in addition, because the first control device can only obtain the resource configuration information of the available resources, the first control device can only open the service by using the resource configuration information of the available resources, and the service corresponding to the NMS and the SDN controller and the configuration of each device in the network are both ensured.
Second embodiment:
fig. 5 is a flowchart illustrating a method for managing and controlling network resource allocation according to a second embodiment of the present invention. In this embodiment, the first control apparatus is further connected to a second control device, and the management and control method includes:
In this step, specifically, the first control device is further connected to the second control device, and the first control device can obtain the second resource demand information of the second control device in real time. Specifically, when the second control device starts or opens the service, the second control device may send the second resource requirement information to the first control device. For example, as shown in fig. 4, assuming that the NMS is a first control device and the SDN controller is a second control device, the first control device is connected to the SDN controller while being connected to the NMS. When the SDN controller starts or opens the service, the first control device acquires second resource demand information of the SDN controller.
In this step, specifically, when the first control device obtains the second resource requirement information of the second control device, the resource configuration information of the available resources in the entire network resources may be sent to the second control device according to the second resource requirement information.
In this way, the first control device sends the resource configuration information of the available resources in the whole network resources to the second control device according to the second resource demand information of the second control device, so that the second control device can only acquire the resource configuration information of the available resources, but cannot acquire the resource configuration information of the unavailable resources in the whole network resources, so that the second control device can only manage the resources by using the resource configuration information of the available resources, but cannot interfere with the unavailable resources, and the conflict between the second control device and the resources managed by the first control device when managing the resources is avoided; in addition, since the second control device can only obtain the resource configuration information of the available resources, the second control device can only open the service by using the resource configuration information of the available resources, thereby ensuring that the service corresponding to the NMS and the SDN controller and the configuration of each device in the network are both provided.
Specifically, when sending resource configuration information of available resources in the whole network resources to the second control device according to the second resource demand information, the resource configuration information of resources occupied by the first control device in the whole network resources, which is reported in real time by the first control device, may be received; then according to the second resource demand information and the received resource configuration information of the resources occupied by the first control equipment in the whole network resources, sending the resource configuration information of the resources not occupied by the first control equipment to the second control equipment; wherein the available resources of the second control device include unoccupied resources of the first control device.
In this way, the first control device can directly acquire the resource configuration information of the resources occupied by the first control device in the whole network resources, so as to acquire the resource configuration information of the resources not occupied by the first control device. In the embodiment, the whole network resources are uniformly managed through the first control device, and when the second control device has a resource demand, the resource configuration information of the resources which are not occupied by the first control device in the whole network resources is sent to the second control device, so that the convenience of the whole network resource management is improved.
