Packet stream redirection processing method for distributed network system

Abstract

The invention discloses a message flow redirection processing method of a distribution network system. The method comprises the following steps: a service board with relatively small MAC address table capacity is arranged as a CLIENT service board, and a service board with relatively large MAC address table capacity is correspondingly arranged as a SERVER service board; the CLIENT service board redirects the received message to the SERVER service board, and the SERVER service board carries out MAC agency operation to a message. The MAC address table on the entire distribution Ethernet switch is adopted to realize unicast two-layer forwarding through a low-price service board with relatively small MAC address table capacity, like a high-price service board with relatively large MAC addresstable capacity. Therefore, broadcast messages on a network and broadcast messages in a user network connected with a two-layer switch can be reduced, and the purposes of reducing the cost of the distribution Ethernet switch and improving the two-layer forwarding performance of the entire system can be achieved.

Description

technical field [0001] The invention relates to a message flow redirection processing method in the field of network communication, in particular to a message flow redirection processing method of a distributed network system in the field of network transmission. Background technique [0002] With the rapid development of the Internet, the Ethernet network has gradually become an indispensable tool in people's daily work and life. Therefore, the requirements for network stability and reliability are getting higher and higher. At the same time, various manufacturers are trying to reduce costs and improve The price / performance ratio of the product. With the improvement of ASIC (Application Specific Integrated Circuit) chip design technology, the Layer 2 and Layer 3 forwarding of Ethernet switches can basically be completed by integrated chips. [0003] In the prior art, the Layer 2 forwarding of the Ethernet Layer 2 and Layer 3 switches is carried out according to the destina...

Problems solved by technology

But on the other hand, since the capacity of each service board for storing the MAC address table is limited, and in order to achieve cost advantages, some service boards with smaller table entries will be selected, which will cause the MAC address table capacity is not the same

During the dynamic learning process of MAC addresses, the service board with a small MAC address table will soon reach the upper limit of capacity, resulting in many MAC addresses that cannot be learned, resulting in the occurrence of A large number of broadcast packets will seriously affect the Layer 2 forwarding performance and network bandwidth
