Abstract

The port bundling method for distributed network exchange system includes the following steps: increasing one self-defined port field 'main port' to the port bundling list of network exchange system and marking the bundling group logically with the main port; substituting the source port of the up message from the sending port to the port bundling group with port expressed in the main port field and sending the substituted message to opposite end via the network plate of the network exchange system; and sending the responding message from the opposite end to the port expressed in the main port field. The method performs flux balance of port bundling via several data stream marking modes to realize the homogeneous distribution of flux and the back-up to various services. In addition, the two-layer translating in MAC learning to 'main port' mode can avoid the MAC learning address vibration problem effectively.

Description

technical field

[0001] The invention relates to network communication technology, in particular to a method for realizing port binding in a distributed system using a network processor. Background technique

[0002] In network communication, the port bundling function is an important function of switches and routers. It can aggregate multiple Ethernet links into a logical link, thereby providing wider link bandwidth.

[0003] In the case of port bundling, when a packet is sent through the bundled port, the system needs to select a port from the bundled group, and the result of the selection should meet the following two requirements: (1) the same flow (specific source and specific destination) application-specific data packets) should be sent from the same port, so as to ensure the order of the same flow data frame (this is necessary in the case of a LAN with a layer 2 switch, because the LAN communication program generally does not consider data frame disorder of). (2) Th...
