Currently, in a network topology structure composed of a plurality of switch devices, configuration and management of the switch devices mainly depend on a network manager, and the network manager can configure and manage the switch devices (also called edge nodes) in the network topology in a machine-by-machine manual configuration mode, which has the disadvantages of huge task amount, low efficiency and high error rate. Moreover, after configuration is completed, node information and configuration information of the current node cannot be stored, and when abnormality occurs in the node, consistency verification cannot be performed, and meanwhile, centralized management cannot be performed on a plurality of switch devices in the network topology.
In order to solve the above problems, embodiments of the present application provide a processing system, a method, an apparatus, and a device for edge access, which implement flexible configuration and management of switch devices in a network topology. Specifically, the embodiment of the application provides a processing system for edge access, which comprises a network routing controller NRC, wherein the controller configures and manages switch equipment in network topology through various southbound protocols (such as NETCONF protocol or SSH protocol), thereby improving the degree of automation and reducing the difficulty of adjusting configuration information. Meanwhile, the processing system of the embodiment of the application also introduces MongoDB to store the switch equipment information and the configuration information, so that consistency verification of the switch equipment configuration can be realized, and normal operation of the switch equipment in the network topology is prevented from being influenced by network abnormality. In addition, the processing system provided by the embodiment of the application can adopt the design of a multi-stage controller to realize centralized management of a plurality of switch devices in different areas.

After the NRC finishes storing the information, the corresponding configuration is issued to the switch equipment connected with the NRC.
In addition, the NRC may receive static configuration information for the NRC for configuration initialization of the NRC. Likewise, the NRC will store static configuration information for the NRC into a database connected to the NRC.

In addition to the configuration request of the non-service resource, the global network routing controller may also receive the configuration request including the service resource information, which is not limited in any way in the embodiments of the present application.

The NRC in the embodiment of the application provides northbound interface service, can support a restful api interface and a kafka message queue interface, and is convenient for network management personnel to adjust and optimally configure a switch connected with the NRC. Specifically, the NRC may receive a configuration request through the northbound interface. Wherein the configuration information of the switch connected with the NRC in the configuration request comprises service resource information or non-service resource information. Wherein the service resource information includes network segment configuration information.

In one possible implementation, receiving the configuration request includes: and receiving a configuration request comprising non-business resource information sent by the global network routing controller through the northbound interface, wherein the configuration information comprises the non-business resource information. Illustratively, as shown in fig. 3, NRC AZ in AZ1 of zone a receives a configuration request including non-service resource information, which is sent by NRC Global (Global network routing controller) through a kafka message queue interface, through a northbound interface.
In another possible implementation, receiving the configuration request includes: and receiving an input configuration request comprising service resource information through the northbound interface, wherein the configuration information comprises the service resource information. As shown in fig. 3, the NRC AZ in AZ1 of the region a directly receives a configuration request including service resource information sent by other devices (clients) through a northbound interface.
And 102, storing configuration information into a database connected with the NRC according to the configuration request.
The NRC in the embodiment of the present application also provides a persistent storage service including functions of initializing a database connected to the NRC, creating or deleting a collection, adding/deleting/querying a document, and the like. Specifically, the NRC is connected to the database, and after receiving the configuration request, the NRC first stores configuration information in the configuration request to the database connected to the NRC. In addition, a database connected to the NRC is used to store a record of the operation of the exchange by the user.
Alternatively, the database connected to the NRC may be a database based on a distributed file store, such as a monodb.
According to the embodiment of the application, the database is introduced to store the resource information of the switch, so that centralized management of resources and consistency verification of configuration can be realized.
And 103, configuring the connected switch according to the configuration information.
The NRC in the embodiment of the present application also provides a configuration generation, configuration issuing service, and static configuration loading service. Wherein the configuration generation service combines and generates an underlying basic configuration set, such as specific routing configurations of interfaces interface, vrf in the switch, primarily from the traffic resources. The configuration issuing service may use SSH protocol or netcon f protocol for configuration issuing. The static configuration loading service mainly adjusts the running state of the controller, and the adjusted parameters comprise the number of threads, the number of queues, the user name, the password and the like of the NRC.
In one possible implementation, the configuration information includes service resource information or non-service resource information, and step 103 specifically includes: and converting the configuration information in the received configuration request into a configuration command executable by the switch, and issuing the configuration command executable by the switch to the switch connected with the NRC through a southbound interface.
The NRC in the embodiment of the present application further provides an on-line and off-line operation service of the switch, including functions of consistency check after the switch is on-line, switch off-line notification, and the like, and mainly senses a connection state of the switch connected with the NRC through a southbound interface of the NRC.
The processing method of edge access, provided by the embodiment of the application, is applied to NRC, and is used for configuring one or more switches connected with NRC by receiving a configuration request comprising configuration information of the switch connected with NRC, storing the configuration information to a database connected with NRC according to the configuration request, and generating a configuration command executable by the switch according to the configuration information. The processing method realizes centralized configuration and management of the switch connected with the NRC, reduces the difficulty of configuration adjustment of the switch, and remarkably improves the configuration efficiency.
Optionally, on the basis of the foregoing embodiment, the method for processing edge access further includes the following steps: and receiving a static configuration parameter of the NRC, and configuring the NRC according to the static configuration parameter. Wherein, the static configuration parameters of the NRC at least comprise the following parameters: thread number, queue number, user name and password, etc.
Optionally, on the basis of the foregoing embodiment, the method for processing edge access further includes the following steps: when configuring the switch, the operation record of the switch is stored in a database. I.e. when the NRC issues an actual configuration (i.e. a configuration command executable by the switch) to the switch, the NRC needs to store the actual configuration in a database connected to the NRC.
Optionally, on the basis of the foregoing embodiment, the method for processing edge access further includes a method for checking consistency of the switch. The consistency check scheme is described in detail below with reference to fig. 4.
Fig. 4 is a flowchart of a processing method for edge access provided in the embodiment of the present application, and as shown in fig. 4, the processing method provided in the embodiment of the present application includes the following steps:
The NRC of the embodiments of the present application provides a data model and common class definition services, including configuration definition classes of switches, dataStore processing classes, and the like. Specifically, when the NRC detects that the switch is on-line through the southbound interface, all resources of the switch are acquired from the database, and a first configuration object is generated according to all the acquired resources.
Specifically, the NRC obtains real-time configuration information from the switch in the form of a file, and parses and generates a second configuration object according to the real-time configuration information.
In the embodiment of the application, the first configuration object and the second configuration object are java classes, such as Vrf class, bgp class and the like, abstracted from the switch configuration, and only the first configuration object is abstracted from the switch configuration information stored in the database, and the second configuration object is abstracted from the current configuration information of the switch.
It can be understood that in the actual operation process, there are various factors that cause the configuration information on the switch to be changed under the condition that the NRC does not sense, for example, the switch is restarted when power is off, abnormal operation occurs to the switch due to irregular operation, and once the configuration information issued to the switch in advance is lost or tampered, the subsequent configuration will also be issued to fail, so that the normal operation of the switch is affected. In order to avoid the above situation, the NRC in the embodiment of the present application needs to obtain the configuration information of the switch from the database and the switch, respectively, to perform configuration object comparison.
The first configuration object and the second configuration object being inconsistent includes a missing, redundant, or erroneous configuration object. Illustratively, the first configuration object includes 5 configuration records, the second configuration object includes 6 configuration records, each configuration record including a target object and a next hop object. It can be seen that the current configuration of the switch is inconsistent with the switch configuration pre-stored in the database, and the switch needs to be reconfigured according to the first configuration object. For example, the first configuration object and the second configuration object each include 5 configuration records, however, the next-hop object in the corresponding 1 configuration records in the first configuration object and the second configuration object is different, which indicates that the configuration information of the current switch may be tampered, and the corresponding configuration of the current switch needs to be adjusted according to the next-hop object in the corresponding configuration record of the first configuration object.
Optionally, in some embodiments, when it is determined that the first configuration object and the second configuration object are inconsistent, an alarm or alert message may also be sent to the terminal of the network manager, so that the network manager reconfigures the switch through the NRC.
Optionally, in some embodiments, a detection period for performing consistency check may be set for NRC, so as to implement periodic inspection, timely inspect the fault of the switch, reduce difficulty of configuration adjustment, and improve stability of the regional control system.
The processing method for edge access, provided by the embodiment of the invention, is applied to NRC, when the switch is detected to be on line through a southbound interface, the resources of the switch are obtained from a database, a first configuration object is generated, meanwhile, the real-time configuration information in the switch is obtained, the real-time configuration information is analyzed, a second configuration object is generated, the first configuration object and the second configuration object are compared, and when the first configuration object and the second configuration object are inconsistent, the switch is reconfigured according to the resources in the database. The processing process realizes consistency verification of the online switch in the regional control system, and when the switch configuration is abnormal, configuration information in the switch is timely adjusted, so that the configuration flexibility is high.
The embodiment of the present application may divide functional modules of a processing apparatus (i.e., NRC) according to the above embodiment of the method, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated modules described above may be implemented either in hardware or in software functional modules. It should be noted that, in the embodiment of the present application, the division of the modules is schematic, which is merely a logic function division, and other division manners may be implemented in actual implementation.
