METHOD FOR ALLOCATING NETWORK RESOURCES IN VIRTUAL NETWORK FUNCTION, COMPOSER AND MANAGER

摘要

A method for allocating network resources in a virtual network function (VNF), a composer and a manager. The method comprises: receiving network service availability identifier (NSAI) information, which is sent by an OSS or a BSS and used for indicating a network service (NS) standby resource; acquiring performance abnormality data of a VNF that has an abnormality; and when it is determined that the VNF has an overload performance or an excessively low performance, according to NS subscription resource information, standby resource information and the performance abnormality data, making a corresponding network service reserved resource handling policy, and sending same to a virtual network function manager and a virtualized infrastructure manager. The embodiments of the present invention can achieve the dynamic adjustment of an NS available resource after an NS is generated and ensure the availability and continuity of the NS.
