Abstract

The invention provides a message forwarding method and a message forwarding device. The method comprises the steps: removing the RPR packaging of a first RPR message when an RPR processing chip receives the first RPR message, so as to obtain a first Ethernet message; the RPR processing chip adds a first RPR label into the first Ethernet message, and sends the first Ethernet message with the firstRPR label to the switching chip through an internal Ethernet port; when the switch chip does not record a first MAC table entry matched with the source MAC address of the first Ethernet message, determining a first virtual port corresponding to the first station identifier according to the first station identifier, and stripping the first RPR label; and the switching chip generates the first MAC table entry and forwards the first Ethernet message from which the first RPR label is stripped. By applying the embodiment of the invention, the processing of the RPR processing chip can be simplified,and the performance and resources of the RPR processing chip can be saved.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] RPR (Resilient Packet Ring, Resilient Packet Ring) is a new type of MAC (Media Access Control) protocol that can run on SONET (Synchronous Optical Network) / SDH (Synchronous Digital Hierarchy) , DWDM (Dense Wavelength Division Multiplexing) and Ethernet, provide flexible and efficient networking solutions for broadband IP metropolitan area network operators. [0003] At present, the Ethernet switch supporting RPR function (can be called RPR switch) mainly connects an RPR processing chip under the switch chip (it can be FPGA (Field Programmable Gate Array, field programmable gate array) or dedicated RPR processing chip) To achieve this, the switching chip and the RPR processing chip are connected through an internal Ethernet port, and data forwarding includes two levels: basic Ethernet forwarding ...
