Description
Technical Field
The invention relates to the technical field of task processing, in particular to a task merging method and device based on an OpenStack DHCP Agent and a computer readable storage medium.
Background
The DHCP Agent is a component of a network module (Openstack Neutron) of a cloud platform open source framework, is used for realizing a DHCP function in a local area network, and serves as a DHCP server. The DHCP Agent runs on a network node in a service fashion and provides DHCP functionality for each network by starting a dnsmasq process for that network.
The DHCP Agent will receive some tasks: such as creation, update, deletion, etc. of a network, subnet, or port. These tasks may involve operations such as creating a dnsmasq process, changing a configuration file for the dnsmasq process, restarting a configuration file for the dnsmasq process, and so on. DHCP Agents restarting the configuration file for dnsemasq in the process flow is a relatively time consuming operation.
At present, Openstack DHCP Agent processing tasks adopt first-come first-processed logic, and some coverable tasks are not distinguished. For example, the update of the network, the subnet and the port can be completely processed according to the final update result. However, based on the current first-come first-processed logic, the configuration file of dnsmasq needs to be restarted every time of updating, which results in unnecessary time-consuming operations being performed for many times. For some tasks with conflicts, for example, port updates, which may involve the same network, a thread lock is used with the network ID as a key to avoid operating the same dnsemasq process, which causes other port updates in the same network to be in a blocked state.
Therefore, how to reduce useless operations and improve the concurrent processing capacity of tasks is a problem to be solved by the technical personnel in the field.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a task merging method based on an OpenStack DHCP Agent according to an embodiment of the present invention is described in detail. Fig. 1 is a flowchart of a task merging method based on an OpenStack DHCP Agent according to an embodiment of the present invention, where the method includes:
s101: a task is received.
Tasks based on the OpenStack DHCP Agent include task types including a network type, a subnet type, and a port type. In the embodiment of the present invention, two different service processing logics may be set for the type of the received task.
S102: and when the resource type of the task is the network or subnet type, adding or covering the task in the task library according to the network identifier recorded in the task library.
For the tasks of the network or the subnet type under the same network, the operation is performed on the configuration file corresponding to the network, so that only the latest task can be reserved in the task library, and unnecessary task processing is reduced.
In an embodiment of the invention, a python ordered dictionary may be used as a task library. The python ordered dictionary ensures the sequence of each task and realizes the ordered execution of each task.
The received tasks of the network or subnet type include tasks of creating, updating or deleting operation of the network or subnet, and the processing of the tasks should be processed according to the final state of the network or subnet, i.e. the latter task can override the former task.
For example, according to the time sequence, the received first task is to update the network, the received second task is also to update the network, and finally the received second task is to be in the final state of the network.
Because the tasks in the same network correspond to the same configuration file, the tasks in the network or subnet type in the same network can be covered, and the tasks in different networks can not execute the covering. In the embodiment of the invention, different networks can be distinguished according to the network identifiers.
S103: and when the resource type of the task is the port type, performing primary addition, secondary addition or secondary covering operation on the task in the task library according to the primary network identifier and the secondary port identifier recorded in the task library.
There are often multiple ports contained in the same network, and each port may have its corresponding task. In view of the fact that tasks corresponding to different ports in the same network all involve restarting of configuration files, and the restarting of the configuration files takes a long time, in the embodiment of the present invention, tasks corresponding to different ports in the same network can be merged, so that the number of times of restarting the configuration files is reduced.
The primary network identification is used for distinguishing the network to which the port belongs, and the secondary port identification is used for distinguishing different ports.
For ease of introduction, a task whose resource type is a port type may be referred to as a port task.
In the embodiment of the present invention, when the network identifier to which the port task belongs does not exist in the task library, the network identifier and the port task thereof need to be added in the task library, and the adding operation may be referred to as primary adding. When the network identifier to which the port task belongs exists in the task library but the port identifier does not exist, the port task needs to be added under the network identifier in the task library, and the adding operation can be called secondary adding. When the network identifier to which the port task belongs exists in the task library and the port identifier exists, it is indicated that the task corresponding to the port is recorded in the task library, and for the port task corresponding to the same port, the covering operation of the port task can be executed, and the covering operation of the port task can be called secondary covering operation.
In practical applications, a corresponding network ID is set for each network, and in the embodiment of the present invention, the network ID may be used as a network identifier for distinguishing different networks. Fig. 2 is a flowchart illustrating a task process for executing a network or subnet type according to a network ID, the process flow includes:
s201: and when the resource type of the task is the network or subnet type, judging whether the network ID of the task exists in the task library.
The processing capacity of the server is limited, and when a large number of received tasks are available, the server cannot process all the tasks at the same time, so that unprocessed tasks need to be cached first.
Each task has its own network, and the task can carry its own network ID, and when the network ID exists in the task library, it indicates that the task under the network has been recorded in the task library. For the network or subnet type task in the same network, the latest task may be used as the final state, and in order to improve the processing efficiency of the task, S202 may be executed at this time.
If the network ID does not exist in the task library, it indicates that the task under the network is not recorded in the task library, and at this time, the task may be recorded in the task library, that is, S203 is executed.
S202: and covering the resource information of the task with the original resource information corresponding to the network ID.
In the embodiment of the present invention, a key-value (key-value) mode may be used to record the task, where the key is the network ID and the value is the resource information. The resource information refers to specific task information to be executed.
When the network ID which is the same as the network ID carried by the received task exists in the task library, the resource information of the received task can be covered by the original resource information which is the original resource information corresponding to the network ID in the task library, and when the server executes the task in the task library, only the task which is recorded latest at present needs to be executed, so that unnecessary tasks executed by the server are reduced, and the task processing efficiency of the server is effectively improved.
S203: and adding the network ID and the resource information of the task into the task library.
When the network ID identical to the network ID carried by the received task does not exist in the task library, it is indicated that the task library does not have the task corresponding to the network ID, and at this time, the received task needs to be added to the task library. Taking the key-value pair as an example, it is necessary to record the network ID of the task as a key and the resource information of the task as a value in the task library.
By recording the tasks in the task library in a key value pair mode, whether the tasks which belong to the same network as the newly received tasks exist can be quickly inquired from the task library, and the inquiring and recording efficiency of the tasks is further improved.
In the embodiment of the present invention, the network ID may be used as the primary network identifier, and the port ID may be used as the secondary port identifier. Fig. 3 is a flowchart illustrating a process of performing a port task according to a network ID and a port ID, the process flow including:
s301: and when the resource type of the task is the port type, judging whether the network ID of the task exists in the primary task library.
In the embodiment of the present invention, in order to distinguish different ports and networks to which the ports belong, the task library may be divided into two levels, namely a primary task library and a secondary task library. The primary task library records the network to which the port belongs, and the secondary task library records the port ID and the port information of the port.
When a new task is received, if the network ID identical to the network ID of the task does not exist in the primary task library, it is indicated that the task of the network to which the port belongs is not recorded in the primary task library, and at this time, the newly received task needs to be added to the task library, that is, S302 is executed.
When a new task is received, if a network ID identical to the network ID of the task exists in the primary task library, it indicates that a task of the network to which the port belongs is recorded in the primary task library, and at this time, it is necessary to further determine whether a task of the port exists, that is, to execute S303.
S302: and adding the resource information of the network ID of the task to the primary task library, and adding the port ID and the port information of the task to the secondary task library.
When adding a port task in a task library, firstly, a network ID of the port task needs to be added as a key in a primary task library, and a port ID and port information of the port task need to be added in a secondary task library. The secondary task library is the value of the network ID. The port information refers to specific port task information required to be executed.
S303: and judging whether the port ID of the task exists in the secondary task library.
When the network ID identical to the network ID of the task exists in the primary task library, it is necessary to further determine whether a port ID identical to the port ID of the task exists in the secondary task library.
When the port ID of the task does not exist in the secondary task library, that is, the port ID identical to the port ID of the task does not exist in the secondary task library, it is indicated that the task of the port is not recorded in the secondary task library, and at this time, the port task needs to be added in the secondary task library, that is, S304 is executed.
When the port ID of the task exists in the secondary task library, that is, the port ID identical to the port ID of the task exists in the secondary task library, it indicates that the task of the port is recorded in the secondary task library, and the task of the same port can be processed in an overlay manner, that is, S305 is executed.
S304: and adding the port ID and the port information of the task to a secondary task library.
Taking the key value pair mode to record the task as an example, when the port ID of the task does not exist in the secondary task library, the port ID is taken as a key, the port information is taken as a value in the secondary task library, and the port task is recorded.
S305: and covering the port information of the task with the original port information corresponding to the port ID in the secondary task library.
When the port ID which is the same as the port ID carried by the received task exists in the task library, namely the port ID of the task exists in the secondary task library, the port information of the received task can be covered by the port information which is originally corresponding to the port ID in the secondary task library, namely the original port information, and when the server executes the task in the task library, only the port task which is recorded at the latest currently needs to be executed, so that unnecessary tasks executed by the server are reduced, and the task processing efficiency of the server is effectively improved.
According to the technical scheme, the task is received; and when the resource type of the task is the network or subnet type, adding or covering the task in the task library according to the network identifier recorded in the task library. For the tasks of the network or the subnet type under the same network, the operation is performed on the configuration file corresponding to the network, so that only the latest task can be reserved in the task library, and unnecessary task processing is reduced. And when the resource type of the task is the port type, performing primary addition, secondary addition or secondary covering operation on the task in the task library according to the primary network identifier and the secondary port identifier recorded in the task library. The second-level covering operation is covering processing executed for tasks of the same port, the second-level adding operation is merging processing executed for tasks of different ports under the same network, and the first-level adding operation is adding new port tasks into a first-level task library. The operation of all ports in the same network finally needs to restart the configuration file, so that the port tasks in the same network effectively reduce the times of restarting the configuration file by executing secondary addition and secondary coverage, and improve the processing speed and the concurrent processing capacity of the tasks.
In practical application, the recording task and the processing task can be regarded as two parallel processing flows, when the number of tasks required to be processed currently exceeds the processing capacity of the server, the tasks to be processed are put into the task library, and the subsequent server can read the tasks from the task library for processing.
When storing port tasks, a primary task library and a secondary task library are divided, so that when reading the tasks, a server needs to acquire a configuration file corresponding to a network ID according to the network ID recorded in the primary task library; reading all port information recorded in a secondary task library to which the network ID belongs, modifying the configuration file according to all the port information, and restarting the modified configuration file.
The port information records the operation to be executed on the corresponding port, and in the embodiment of the invention, all port tasks in the same network can be merged, and at the moment, the restarting of the configuration file is only needed to be executed once.
For example, 10 pieces of port information are recorded in the secondary task library to which one network ID belongs, at this time, the relevant information in the configuration file may be modified according to the operation mode recorded in each piece of port information, and finally, the modified configuration file is restarted, and for 10 port tasks in the same network, the restart operation of the configuration file is only needed to be performed once. Compared with the prior art that 10 port tasks need to execute 10 times of restarting of the configuration file, the concurrent processing capacity of the tasks is increased and the processing time of the tasks is greatly shortened by carrying out the merging processing on the port tasks.
