Abstract

The disclosure provides a method, device and system for updating a YANG model file library, and relates to the field of software-defined networks. The method includes: when the content of the YANG model file library corresponding to the virtual slice instance changes, the network device re-determines the module-set-id value corresponding to the YANG model file library; sends the YANG model file library update message to the corresponding virtual slice instance The client, so that the client judges whether to update the YANG model file library according to the YANG model file library update message, wherein the YANG model file library update message includes a virtual slice instance identifier and a module-set-id value. This disclosure enables the client corresponding to each virtual slice instance to update the corresponding YANG model file library in a timely and on-demand manner, avoiding unnecessary global updates and improving operation and maintenance efficiency.

Description

technical field [0001] The present disclosure relates to the field of software-defined networks, and in particular to a method, device and system for updating a YANG model file library. Background technique [0002] In software-defined networking, the Netconf network management protocol is a mainstream management protocol. The Netconf protocol itself standardizes and defines data links, message formats, etc., but does not provide clear regulations on specific network device modeling methods. ; YANG modeling language is an advanced network equipment modeling language, and its corresponding YANG model is the mainstream data model format adopted by the Netconf network management protocol. [0003] In terms of specific implementation, the Netconf-based management model consists of two parts, namely the Netconf server (managed network device) and the Netconf client (network administrator). Its specific architecture is as follows: figure 1 As shown, in the specific implementation...
