Method, system, device and storage medium for controlling packet forwarding based on multi-level flow table

Abstract

The invention relates to the field of communication technology, and discloses a method, system, device and storage medium for controlling message forwarding based on a multi-level flow table, which are used to simplify the message forwarding process and improve message flow forwarding efficiency. The method includes: matching the first packet received by the user with the first packet flow entry of the IP packet through the transponder, and uploading the first packet to the SDN controller when the matching is successful to learn the first packet flow entry of the first packet. address information of a message; learn the first message reported by the forwarder through the SDN controller, generate the message forwarding flow entry corresponding to the user, and forward the message The flow entry is sent to the forwarder, wherein the first message and the second message are different messages; the second message received from the user and the message are forwarded by the forwarder The flow entry is matched, and the second packet is forwarded when the match is successful.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, system, device and storage medium for controlling message forwarding based on a multi-level flow table. Background technique [0002] In the network function virtualization networking scenario, the BRAS (Broadband Remote Access Server, Broadband Remote Access Server) device serves as the portal for users to experience various Internet services. It has complex functions and a large number of devices, which is the key to the IT transformation of the entire IP bearer network. However, with the surge in the number of home broadband users and the rapid development of new services such as 4K HD and the Internet of Things, traditional BRAS equipment is also faced with a series of operations such as low resource utilization, complex management, operation and maintenance, and slow launch of new services. problem. To this end, SDN (Software Defined Network,...
