Problems solved by technology

Traditional loopback processing usually uses internal physical ports, which have only port attributes and no service attributes. Therefore, after the loopback, when entering the chip for internal processing again, the service attributes are lost and can only be processed according to the report. Find and forward the text in the chip for editing

Abstract

The invention discloses a method and device for achieving multistage message editing service control on the basis of a logic port. When a message reenters a chip to be subjected to loopback treatment, service identification is performed by carrying a chip internal logic port, namely the messages is forwarded from a chip physical entry to the internal logic port by means of lookup. The number of the logic port is carried when the loopback is performed and the message participates in lookup control by means of the logic port when loopback forwarding is carried out. The method and the device can be used for mutual forwarding of MPLS and VPN, the processing of IP tunnel, NVGRE, VXLAN messages, achieve access control, flow control, and forwarding requirements in a service level so as to flexibly control a network behavior and simplifies the implement of the multistage message editing of the message in a communication system.

Description

technical field [0001] The invention relates to a multi-level message editing service control technology, in particular to a method and device for realizing multi-level message editing service control based on logical ports. Background technique [0002] With the development of the network, it is necessary for one network to pass through another network, such as the fast-growing NVGRE (Network Virtualization GRE), VXLAN (Virtual Extensible Local Area Network) and other emerging large-scale two-layer services, as well as the traditional VPN (Virtual private network) mutual conversion, that is, L2VPN to L3VPN, L3VPN to L2VPN, these services require switching equipment for multi-level loopback editing. [0003] When network forwarding requires multiple editing of packets, for example, when switching between VPNs, L2VPN to L3VPN, or L3VPN to L2VPN, or rerouting after VXLAN encapsulation, due to the limitation of the forwarding chip itself or to achieve flexibility, the packet E...
