Method for forwarding data of virtual network router in centralized mode

Abstract

The invention discloses a method for forwarding the data of a virtual network router in a centralized mode. According to the method for forwarding the data of the virtual network router in the centralized mode, control planes of virtual network router living examples and data planes of the virtual network router living examples are separated, the control planes operate inside the virtual network router living examples and are responsible for routing computation, the data planes are transferred into an inner core of the virtual network router, a data centralized forwarding engine is formed by the data planes of the network router living examples on the bottom layer of virtual network router equipment, forwarding tables of all the virtual network router living examples are organized and compressed into a shared forwarding table by the data centralized forwarding engine, and forwarding of data of all the living examples on a virtual router node is controlled according to the shared forwarding table. The method for forwarding the data of the virtual network router in the centralized mode has the advantages that cost for data forwarding of the virtual network router can be effectively reduced, link-speed forwarding performance of the virtual network router can be achieved, the number of the virtual network router living examples supported by the virtual network router can be increased, and virtual network data forwarding performance is improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and is especially applicable to data centers, cloud platforms and other next-generation new Internet networks supporting network virtualization, and in particular relates to a unified data forwarding method of a virtual network router. Background technique [0002] In recent years, there have been many new technological breakthroughs related to backbone network equipment in the Internet field, the most important of which is virtual network technology. A virtual network is a plurality of independently operating logical networks built on a public network hardware infrastructure after abstracting and dividing physical network resources using virtualization technology. As the core device of the virtual network, the virtual router is built on the traditional hardware routing device, uses software technology to reuse various resources of the hardware routing device, realizes the function simulatio...

Problems solved by technology

In this forwarding method, data packets need to go through multiple mappings from physical NICs to virtual NICs to enter the virtual router instance to complete the routing lookup. The forwarding delay is long, and the data planes of each instance will compete for CPU, cache, high-speed data Paths and other physical resources greatly reduce the routing lookup efficiency
