At present, 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 huge task load, low efficiency and high error rate. Moreover, after configuration is completed, node information and configuration information of the current node cannot be stored, when the node is abnormal, consistency check 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 foregoing problems, embodiments of the present application provide a system, a method, an apparatus, and a device for processing edge access, so as to implement flexible configuration and management of switch devices in a network topology. Specifically, an embodiment of the present application provides a processing system for edge access, where the system includes a network routing controller NRC, and the controller configures and manages switch devices in a network topology through multiple southbound protocols (for example, NETCONF protocol or SSH protocol), so as to improve an automation degree and reduce difficulty in adjusting configuration information. Meanwhile, MongoDB is introduced into the processing system of the embodiment of the application to store the switch equipment information and the configuration information, so that consistency verification of switch equipment configuration can be realized, and normal operation of the switch equipment in network topology is prevented from being influenced by network abnormity. In addition, the processing system provided by the embodiment of the application can adopt the design of a multi-level controller to realize the centralized management of a plurality of switch devices in different areas.

The configuration request received by the NRC comprises the following two types: the first is to receive non-service resource information, such as switch information, etc., for performing configuration initialization on a switch device connected to the NRC. And secondly, receiving service resource information, such as network segment configuration information and the like, for adapting to the service. For NRC, whether it is non-traffic resource information or traffic resource information, the NRC stores the information in a database connected to the NRC. And after the NRC finishes information storage, issuing corresponding configuration 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. Similarly, the NRC may store the static configuration information for the NRC in a database connected to the NRC.

For any one of the regional control systems, the regional control system includes a network routing controller NRC, a database connected to the NRC, and at least one switch device connected to a southbound interface of the NRC.
The global network routing controller shown in fig. 2 primarily receives a configuration request including non-traffic resource information as the only entry to the global switch management. The registration and deletion of the switch are both handled by the global network routing controller, which, after receiving the registration and deletion requests, persists the data in a database (such as the global database shown in fig. 2) connected to the global network routing controller, and then sends a kafka message to the NRC in the zone control system of each zone. 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 this embodiment of the present application.
It should be noted that, the NRC provided in the embodiment of the present application is a network routing controller based on SDN technology.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a flowchart of a processing method for edge access according to an embodiment of the present application, where the processing method for edge access according to the embodiment is applicable to the NRC shown in fig. 1 or the NRC AZ shown in fig. 2, as shown in fig. 3, the processing method includes the following steps:
The NRC in the embodiment of the present application provides a northbound interface service, and may support a restful api interface and a kafka message queue interface, so that a network manager may conveniently adjust and optimally configure a switch connected to the NRC. In particular, the NRC may receive the configuration request through a northbound interface. The configuration information of the switch connected with the NRC in the configuration request comprises service resource information or non-service resource information. The service resource information comprises network segment configuration information. The non-service resource information comprises switch information, and the switch information comprises basic information such as management IP, management port, AZ information and the like of the switch.
In one possible implementation, receiving the configuration request includes: and receiving a configuration request which is sent by the global network routing controller and comprises non-service resource information through a northbound interface, wherein the configuration information comprises the non-service resource information. Exemplarily, as shown in fig. 3, NRC AZ in AZ1 of zone a receives, through a northbound interface, a configuration request including non-service resource information sent by NRC Global (Global network routing controller) through a kafka message queue interface.
In another possible implementation, receiving the configuration request includes: and receiving an input configuration request comprising service resource information through a northbound interface, wherein the configuration information comprises the service resource information. Exemplarily, as shown in fig. 3, NRC AZ in AZ1 of area a directly receives a configuration request including service resource information sent by another device (user side) through a northbound interface.
And 102, storing the configuration information into a database connected with the NRC according to the configuration request.
The NRC in the embodiments of the present application also provides persistent storage services, including functions of initializing a database connected to the NRC, creating or deleting collections, adding/deleting/querying documents, and the like. Specifically, the NRC is connected to the database, and after receiving the configuration request, first stores the configuration information in the configuration request to the database connected to the NRC. In addition, the database connected to the NRC is used to store records of the user's operations on the switch.
Alternatively, the database connected to the NRC may be a database based on distributed file storage, such as MONGODB.
The embodiment of the application introduces the database to store the resource information of the switch, and can realize centralized management of resources and consistency check of configuration.
And 103, configuring the connected switches according to the configuration information.
The NRC in the embodiment of the present application further provides a configuration generation service, a configuration delivery service, and a static configuration loading service. The configuration generation service mainly combines and generates a bottom-layer basic configuration set according to service resources, such as interface, Vrf and other specific routing configurations in the switch. The configuration issuing service can use SSH protocol or NETCONF protocol to perform configuration issuing. The static configuration loading service mainly adjusts the running state of the controller, and the adjusted parameters comprise the thread number, the queue number, the user name, the password and the like of the NRC.
In a possible implementation manner, 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 the southbound interface.
The NRC in the embodiment of the present application further provides a switch offline operation service, including functions such as consistency check after the switch is online, switch offline notification, and the like, and mainly senses a connection state of the switch connected to the NRC through a southbound interface of the NRC.
The method for processing edge access provided by the embodiment of the application is applied to NRC, and configures one or more switches connected with NRC by receiving a configuration request comprising configuration information of the switches connected with NRC, storing the configuration information into a database connected with NRC according to the configuration request, and generating a configuration command executable by the switches 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 obviously 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 static configuration parameters of the NRC, and configuring the NRC according to the static configuration parameters. Wherein, the static configuration parameters of NRC at least comprise the following parameters: number of threads, number of queues, 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 the switch is configured, the operation record of the switch is stored in the database. I.e. when the NRC issues the actual configuration (i.e. the switch executable configuration commands) 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 processing method for edge access further includes a consistency check method for 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 according to an embodiment of the present disclosure, and as shown in fig. 4, the processing method according to the embodiment of the present disclosure includes the following steps:
The NRC of the embodiment of the present application provides a data model and a common class definition service, including a configuration definition class of a switch, a datastoreore processing class, and the like. Specifically, when the NRC detects that the switch is online through the southbound interface, all resources of the switch are acquired from the database, and the first configuration object is generated according to all the acquired resources.
Specifically, the NRC obtains the real-time configuration information from the switch in a file form, and generates the second configuration object by parsing according to the real-time configuration information.
In this embodiment, the first configuration object and the second configuration object are java classes, such as Vrf class and Bgp class, which abstract the switch configuration, except that 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 may cause the configuration information on the switch to be changed under the condition that the NRC is not aware, for example, the switch is abnormal due to power failure and restart of the switch and irregular operation, and once the configuration information issued to the switch in advance is lost or tampered, the subsequent configuration will also be failed to be issued, which affects the normal operation of the switch. In order to avoid the above situation, the NRC according to the embodiment of the present application needs to obtain the configuration information of the switch from the database and the switch, respectively, and perform the configuration object comparison.
The first configuration object and the second configuration object are inconsistent including a lack, redundancy, or error of the configuration objects. Illustratively, the first configuration object includes 5 configuration records and the second configuration object includes 6 configuration records, each of which includes a target object and a next hop object. As can be seen, 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. Illustratively, the first configuration object and the second configuration object each include 5 configuration records, however, the next hop object in 1 corresponding configuration record 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 it is necessary to adjust the corresponding configuration of the current switch according to the next hop object of the 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 not consistent, an alarm or a prompt message may be further sent to a terminal of a network manager, so that the network manager reconfigures the switch through the NRC.
Optionally, in some embodiments, a detection cycle for performing consistency check may be further set for NRC, so as to implement periodic inspection, timely troubleshoot the switch failure, reduce difficulty in configuration adjustment, and improve stability of the regional control system.
The method for processing edge access provided by the embodiment of the application is applied to NRC, when the south interface detects that a switch is online, the resources of the switch are obtained from a database to generate a first configuration object, meanwhile, real-time configuration information in the switch is obtained, the real-time configuration information is analyzed to generate a second configuration object, and the switch is reconfigured according to the resources in the database when the first configuration object and the second configuration object are not consistent through comparison. The consistency check of the online switch in the area control system is realized in the processing process, when the configuration of the switch is found to be abnormal, the configuration information in the switch is timely adjusted, and the configuration flexibility is high.
In the embodiment of the present application, functional modules of the processing apparatus (i.e., NRC) may be divided according to the method embodiments, 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 module can be realized in a form of hardware or a form of a software functional module. It should be noted that, in the embodiment of the present application, the division of the module is schematic, and is only one logic function division, and there may be another division manner in actual implementation. The following description will be given by taking an example in which each functional module is divided by using a corresponding function.
