Abstract

The invention provides a method for multiple broadcasting and repeating on the Intel IXP2400 network processor, which belongs to computer network communication field, the method includes: the receiving model receives the message from the outer port, which is transmitted to the enclosing model (EM) after being processed by the processor model, the enclosing model (EM) searches the multi-broadcast adjoined enclosing table (DMAT) according to the index of multiple broadcast (MID), the table is a chain table, each item stores a export message enclosing format information, then sends a multi-broadcast message head buffer, the message head content is stored in the buffer, forms the multi-broadcast message head META, the META is looped at front of the message SOP META, forms a message chain table, the message is transmitted to the queue managing model (QM), the transmitting dispatching model (TXS) dispatches the package to the transmitting model (TX), then the message is transmitted by the transmitting model. The invention amends the message head only, the body is not duplicated, and the repeating efficiency is high.

Description

Technical field

[0001] The invention belongs to the field of computer network communication, and in particular relates to a method for realizing multicast forwarding on an Intel IXP2400 network processor. Background technique

[0002] Referring to Figure 1, at present, the message processing flow of the Intel IXP2400 network processor is as follows: the receiving module (RX) receives the message from the external port, and then sends it to the processing module (PM), and sends it to the second floor after the processing module is processed The encapsulation module (EM) sends the queue management module (QM) after encapsulation, and then sends the scheduling module (TXS) scheduling packet to the sending module (TX), and finally the sending module sends the message. The queue management module and the sending scheduling module are based on packet management and scheduling, and each processing only schedules one message to the sending module (TX), and the sending module sends t...
