Problems solved by technology

However, this solution cannot judge the traffic of the current NFV gateway. Even if the CPU of the current NFV gateway is found to be busy and the new NFV gateway is copied, the load balancing LB cannot be used with the NFV gateway, so there is no way to transfer some tenants of the current NFV gateway. of network traffic migrated to the new NFV gateway

Abstract

The application provides a gateway adjustment method and device, which are applied to a server. The server comprises a plurality of network function virtualization (NFV) gateways; when the flow of a current NFV gateway exceeds a flow migration threshold, an NFV gateway is newly added in the server; and the flow of the current NFV gateway is migrated to a newly added NFV gateway. Dynamic adjustmentof the number of the NFV gateways in the server is realized, and smooth migration of flow is realized; in addition, through flow migration, the situation that when the flow is in the previous NFV gateway, because the flow on the NFV gateway is too much, messages cannot be processed in time, and consequently the messages are lost is avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a gateway adjustment method and device. Background technique [0002] At present, the ability of cloud computing is getting stronger and stronger. The routers used as gateways can now be completely replaced by gateways in the form of Network Functions Virtualization (NFV), referred to as NFV gateways. However, since the NFV gateway also exists in the server in the form of a virtual machine, the NFV gateway and the user virtual machine need to share the hardware resources of the server. If the number of NFV gateways is too large, the hardware resources available to the user virtual machine will be too few; if the number of NFV gateways is too small, the network resources of the user virtual machine may be insufficient, which will cause the user virtual machine to freeze. Therefore, how to dynamically adjust the number of NFV gateways in the server is a questi...
