Abstract

The invention provides a message forwarding method and apparatus. The method comprises the following steps: receiving a downlink data message, and when the destination MAC address of the downlink datamessage is an MAC address of an ESGW device, de-packaging the downlink data message into a downlink IP data message; matching an ARP table entry of an IP address of a target user terminal according to a target IP address of the downlink IP data message, and obtaining a session identifier of the target user terminal; determining a length field of a PPPOE header via a microcode, and obtaining a pre-stored fixed value field of the PPPOE header from a data storage area; packaging the downlink IP data message into a downlink PPPOE data message according to the session identifier of the target userterminal, the length field of the PPPOE header and the fixed value field of the PPPOE header, and forwarding the downlink PPPOE data message through an outlet port of the ARP table entry of the IP address of the target user terminal. By application of the message forwarding method and apparatus provided by the embodiment of the invention, the PPPOE package of three-layer forwarding messages of agateway device can be implemented.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding method and device. Background technique [0002] With the development of SDN (Software Defined Network, software-defined network) technology and NFV (Network Function Virtualization, network function virtualization) technology, building a comprehensive multi-service access edge to achieve multi-service integration is the future MAN, access A focus of network access transformation. As the core of the access edge: BRAS (Broadband Remote Access Server, broadband remote access server) equipment is a key point in the transformation of the integrated multi-service access edge. One of the schemes for BRAS to carry out comprehensive multi-service access edge transformation is to realize the virtualization of BRAS. [0003] However, practice has found that in the existing BRAS virtualization implementation scheme, the gateway device cannot implement PP...
