Method, device and system of HELLO message interaction on the basis of NETCONF (The Network Configuration Protocol)

Abstract

One embodiment of the present invention discloses a method, device and system of HELLO message interaction on the basis of NETCONF (The Network Configuration Protocol). The method provided by the invention comprises: a server is configured to allow itself capacity information, first identification information distributed for establishment of a link with a client and second identification information for the representation of the change state of service module information of the server to be carried in a first HELLO message, and the server is configured to sent the first HELLO message to the client; the server is configured to receive an acquisition request sent by the client; and the server is configured to send itself service module information to the client according to the acquisition request.

Description

technical field [0001] The invention relates to network configuration management technology, in particular to a method, device and system for HELLO message interaction based on NETCONF protocol. Background technique [0002] The Network Configuration Protocol (NETCONF, TheNetworkConfigurationProtocol) is a protocol that provides configuration management of network data devices, and uses Extensible Markup Language (XML) to transfer data and protocol information. According to the NETCONF protocol, when the client and server establish a connection, both parties need to send HELLO messages to each other; moreover, the HELLO message sent by the server to the client includes not only the capabilities supported by the server itself, but also Information about all business modules supported by the server should be included. [0003] However, with the development of network technology, many large-scale server-side network devices currently support a very fine division of business mo...

Problems solved by technology

[0003] However, with the development of network technology, many large-scale server-side network devices currently support a very fine division of business modules, resulting in a large number of business modules supported by network devices. Usually, server-side network devices can support hundreds or thousands of Business modules; correspondingly, too many business modules will also increase the number of related information of the business modules; therefore, the length of the HELLO message used by the server to establish a link with the client will be very large

[0004] When the length of the HELLO packet exceeds the maximum packet length supported by the client device, it will cause the server to fail to send the HELLO packet, which will lead to the failure of establishing a link between the client and the server through the NETCONF protocol. The problem that the success rate of establishing a link with the server through the NETCONF protocol is low
