The linkage polymer method realizes linkage polymer and load even through terminal property list, Trunk list, mapping list and message transfer process.

Description

Technical field [0001] The present invention relates to a combination technology of communication equipment, in particular to a stacking technology of Ethernet equipment. Background technique [0002] Currently, fixed port switches (such as 24 10 / 100M ports or 48 10 / 100M port switches) have been widely used at the edge of the network and in enterprises due to their simple configuration and low cost. However, as network traffic and its distribution are undergoing significant changes, in the past client-to-server access (such as web access from browsers to the Internet) dominated network traffic, but today’s traffic model is becoming diversified, such as voice The instant communication with the image has caused a sharp increase in client-to-client access, and the traffic between edge switches is increasing. As the network scale continues to increase, the scalability of fixed-port switches is greatly challenged. Device stacking technology solves this problem. Connecting several swit...

Problems solved by technology

The following algorithms are used: loop detection algorithm, which uses the polling method to evenly distribute the traffic to each port, but its disadvantage is that a small amount of data packet timing may be confused at the receiving end; adaptive algorithm, the maximum possible The traffic is evenly distributed to each port, and the calculation amount is relatively large; the static algorithm can ensure that each data packet can correctly reach the designated port, but it lacks flexibility and the speed is relatively slow

[0011] In practical applications, the above solutions have the following problems: in the existing daisy chain stacking mode, one GE or two GEs are generally used as stacking ports, and the stacking link has only one GE bandwidth. For a long time, congestion and packet loss are prone to occur; if the stacking port adopts a special design to accelerate to 2G or 2.5G, the design will be more difficult, and it will easily cause waste of switching bandwidth; the existing star stacking mode requires a dedicated high-speed switching Center, expensive, not enough redundancy, not enough reliability

[0012] The main reason for this situation is that the existing daisy chain stacking mode can only use a single port as a stacking port; while the existing star stacking mode must use a high-speed switching center
