Landmark separation message forwarding method and device, switching chip and storage medium

Abstract

The invention discloses a landmark separation message forwarding method and device, a switch chip and a storage medium. The landmark separation message forwarding method comprises the steps that S1, asystem is initialized, and a message is received; s2, acquiring a message entry port, and querying a port enable bit of a landmark separation register; s3, analyzing the Ethernet type of the Ethernetmessage; s4, judging a port enable bit value of the landmark separation register; s5, judging whether the type of the Ethernet message is equal to the Ethernet type of the standard separation messageregister or not, if not, forwarding the message according to a traditional message, and if yes, entering the step S6; and S6, separating the message and forwarding the message according to the standard. According to the invention, a user can flexibly configure the support of the landmark separation message according to the specific usage scenario of the switch chip, so that the adaptability of the ASIC chip is enhanced; the matching range of the recognition length can be 1-128bit, so that the expansibility is high; in addition, the ASIC chip supports the traditional message and the standard separation message at the same time, so that the additional cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of message forwarding, and in particular relates to a message forwarding method, equipment, switching chip and storage medium for separated targets. Background technique

[0002] The network architecture of separation of landmarks is based on the existing Internet to solve the problems of mobility, security and routing stability caused by the "ambiguity" of IP addresses, that is, the dual attributes of identity and address. At present, the ASIC (Application Specific Integrated Circuit) Ethernet switching chip realizes the forwarding of traditional IP packets, and two schemes can be adopted for the forwarding of new types of packets with separated targets. The upper-layer protocol software performs addressing and forwarding, and the second is to develop FPGA (Field-Programmable Gate Array) to perform special forwarding processing for such messages.
