Problems solved by technology

[0004] However, the above-mentioned process of forming an IRF stack is cumbersome. Each VNF device needs to be restarted after the stack interface is set and the stack member number is configured, and the user selects a physical server, which is prone to uneven selection of physical servers, which in turn leads to unbalanced load

Abstract

The embodiment of the invention discloses an establishment method and an establishment device of a virtual network function VNF device. A VNF manager determines which physical sever is going to be equipped with the VFM device according to load conditions of the managed physical server and a preset load balancing algorithm, then establishes the VNF device in the physical server and stores a recognizable stack configuration command of the VNF device into a preset position, so the VNF device is allowed to read and execute the stack configuration command from the preset position when being started on the physical server, thereby finishing configuration of the VNF device, collecting topology information and participating a role campaign to form IRF stacks. In the whole process, the VNF device is free from restarting, so restarting frequency of the VNF device is reduced and occurrence of unbalanced condition of server load is avoided.

Description

technical field [0001] The invention relates to the technical field of virtualization, in particular to a method and device for creating a virtual network function (VNF) device. Background technique [0002] Intelligent Resilient Framework IRF (Intelligent Resilient Framework) is to connect multiple devices together through stack ports and virtualize them into a "combined device". The user manages this "combined device" to manage all devices in the stack. All individual devices in an IRF stack are called member devices. Each member device and neighboring member devices exchange IRF Hello packets to collect the topology of the entire IRF. Each member device locally records its known topology information. When a member device starts up, it only records its own otherid2ology information. When the state of the IRF port becomes up, the member device will periodically send the known topology information from the IRF port in the up state; after receiving the information, the ne...
