Abstract

The invention provides a method, device and system for updating a YANG model file library, and relates to the field of software defined networks. The method comprises the following steps: when the content of a YANG model file library corresponding to a virtual slice instance is changed, network equipment re-determines a model-set-id value corresponding to the YANG model file library; and a YANG model file library update message is sent to a client corresponding to the virtual slice instance, and the YANG model file library update message is sent to a client, so that the client judges whether to update the YANG model file library or not according to the YANG model file library update message, and the YANG model file library update message comprises a virtual slice instance identifier and amodel-set-id value. According to the method and the device, the client corresponding to each virtual slice instance can update the corresponding YANG model file library as required in time, unnecessary global update is avoided, and the operation and maintenance efficiency is improved.

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...
