Embodiment 1

[0039] This embodiment adopts image 3 The IRF3 network structure diagram shown, such as image 3 As shown, port U1 and port U2 are both uplink inbound ports of PE, port information of port U1 is (M1, U1), port information of port U2 is (M2, U2); port U3 is downlink inbound port of CB1, port The information is (M3, U3); port U4 is the downlink ingress port of CB3, and the port information is (M4, U4); both CB1 and CB2 have MAC address entries (0-0-2, M2, U2), namely The user equipment with the MAC address 0-0-2 is connected to the port U2 of the PE; CB1 and CB2 are directly connected CBs of the PE respectively.

[0040] Assuming that the PE is a centralized PE, the downlink outbound port S1 of CB1 and the downlink outbound port S2 of CB2 are both enabled with the MOD mapping function in the outbound direction. In the following, CB1 sends downlink packets to port U2 of PE through port U3, and PE through port U2 Replying an uplink message to port U3 of CB1 is taken as an examp...

Embodiment 2

[0075] This embodiment still adopts the parameter settings of method embodiment 1. Method embodiment 1 is a centralized PE, and the centralized PE is proxy forwarding in the technical solution of the present invention, while the distributed PE is local forwarding in the technical solution of the present invention. Embodiment Taking distributed PE as an example to further illustrate the technical solution of the present invention, taking CB3 to send a downlink message to port U2 of PE through port U4, and PE to reply an uplink message to port U4 of CB3 through port U2 as an example to explain the technical solution of the present invention Be explained.

[0076] Such as Figure 5 Shown, is the flow chart of this embodiment, comprises the following steps:

[0077] Step 501: CB3 receives a downlink message through port U4, and sends it to CB2 through an IRF link.

[0078] In this step, the downlink message carries the source MAC address (0-0-4), the destination MAC address (0-0...

Abstract

The invention discloses a message processing method and equipment. The method is applied to a system including a CB and a PE. When a PE receives an uplink message carrying a destination MAC address, it Query the locally saved MAC address entry, determine the destination port information of the uplink message, and query the locally saved outbound port entry according to the determined destination port information, and determine the uplink outbound port of the uplink message; the determined destination port The information is carried in the uplink message and sent from the determined uplink outbound port to the CB directly connected to the determined uplink outbound port for forwarding. This processing method can ensure the shortest forwarding path so that as few CBs as possible participate in the Packet forwarding not only saves bandwidth resources between CBs, but also reduces the packet loss rate caused by CB failures.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message processing method and device. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of the third generation Intelligent Resilient Framework (Intelligent Resilient Framework3.0, IRF3) system, the IRF3 system includes a control bridge (Control Bridge, CB, such as figure 1 CB1 and CB2 shown) and port expansion equipment (Port Extender, PE, figure 1 Only one is shown in ), where the PEs can be distributed PEs or centralized PEs, and form port extension PEX links with CB1 and CB2 respectively, and form IRF links between CB1 and CB2. [0003] exist figure 1 Among them, the uplink egress port of PE is the port on the PE side of the PEX link, such as port P1 and port P2; The ports are ports on the CB side on the PEX link, such as port S1 and port S2, and the downlink inbound port of CB is the port on the CB side that receives down...
