Description
Technical Field
The invention relates to the technical field of data network center equipment management, in particular to a method for managing network equipment based on a NETCONF proxy server.
Background
Under the wave of the national vigorous development of new capital construction, the data center construction becomes the development key project of the new capital construction. With the large-scale deployment of data centers, large data center cluster plans to accommodate even more than 100 million servers.
Most of the existing management schemes for data center Network devices adopt NETCONF/YANG, NETCONF (Network Configuration Protocol) selects an XML language readable by human and machine in a data transmission format, and YANG (yet antenna Next generation) is a data modeling language for defining data transmitted through Network management protocols such as NETCONF and restcon. YANG is a modular language that represents data structures in an XML tree format with many data types built in. Additional application-specific data types may be derived from the built-in data types.
RESTCONF is another IETF standard, which implements NETCONF functions on the basis of RESTful interfaces, and RESTCONF supports XML or JSON as codes and YANG as data modeling language, and because of the rapid development of the internet and the widespread application of RESTful interfaces, the management of network devices is more and more inclined to adopt the scheme of RESTCONF/YANG.
With the development of technology, RESTCONF/YANG is adopted by more and more manufacturers to manage network devices, for example, the current popular network operating system of an open source switch, namely, the network operating system, SONIC, only supports RESTCONF/YANG management devices, but does not support NETCONF/YANG. However, some of the traditional equipment manufacturers, such as Huaye, Zhongxing, Sharp, etc., choose to use the old NETCONF/YANG to manage the equipment. Therefore, a network operating system is required to maintain two sets of RESTCONF/NETCONF systems at a server side at the same time, so that the complexity of the system is greatly increased, and the development and maintenance difficulty of a network management system is improved.

According to the embodiment of the invention, the method for managing the network equipment based on the NETCONF proxy server is provided, which comprises the following steps:
establishing a NETCONF transmission method SSH and an XML transmission format;
establishing a NETCONF proxy server, and sending information in an XML transmission format to the NETCONF proxy server through SSH;
converting the XML transmission format message into a JSON transmission format message through a message conversion mechanism in the NETCONF proxy server, mapping a NETCONF control method contained in the NETCONF proxy server to an RESTCONF control method, and then sending the JSON transmission format message to an REST server of the network equipment through an HTTP transmission method;
and the REST server analyzes the message in the JSON transmission format, and sends control information of the message in the SON transmission format to the network equipment to realize the control and management of the network equipment.
Further, if the user needs to send the RESTCONF management information, the RESTCONF management information is sent to the REST server through an HTTP transmission method.
Further, the RESTCONF management information is sent to the REST server through an HTTP transmission method without passing through a NETCONF proxy server.
Further, the network device includes: switch, router.
Furthermore, a standard Restful protocol and a Yang modeling language are adopted to analyze messages in the JSON transmission format.
Furthermore, a Yang modeling language and a NETCONF equipment management protocol are adopted to establish a NETCONF transmission method SSH and an XML transmission format.
Further, the XML transmission format includes network device node information and a network device management method.
Further, the message conversion mechanism is a message conversion mechanism from NETCONF to RESTCONF.
According to the method for managing the network equipment based on the NETCONF proxy server, the invention simultaneously supports two sets of RESTCONF/NETCONF network equipment management schemes on the aspect of ensuring the consistency of the interface, greatly reduces the complexity of the equipment server and improves the stability of the system, and has important significance in practical application.
