Method and switch apparatus for managing packet of Ethernet stacking system

Abstract

The invention discloses a method for managing messages in an Ethernet stacking system, comprising the following steps: firstly, the number of ports of various target devices to which the messages are sent is respectively calculated according to the target device number and the port number in the messages; secondly, judgment is made whether the target devices to which the messages are sent are primary devices or secondary devices and message information is filled into message formats according to the difference of the target devices; when the primary devices sent the messages to a plurality of ports of the same secondary device and the same local area network number, the message formats are filled by means of compressing partial message information and the messages are packaged; thirdly, transmission of the messages is started; and fourthly, the messages are received by the target devices and transmitted to the ports. By adoption of the method and a device for managing the messages, when a plurality of messages with the same content are sent by the primary devices, the information transmission time and the information amount between the primary devices and the secondary devices are reduced and the bandwidth utilization rate and the network reliability are improved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for managing messages in an Ethernet stacking system and a switch device. Background technique [0002] Ethernet stacking is a commonly used method to expand ports at present. The biggest advantage of stacking technology is that it provides simplified local management, that is, a group of switch devices can be managed as one object. A stacking system usually consists of a master device and multiple slave devices. Each device includes a management unit and a switching unit. The master device and slave devices are connected through relatively high-speed ports. The master device is responsible for the management of the entire system and the operation of the protocol. . [0003] The most common networking topologies of a stack system are chain and ring. The ring topology can be transformed into a chain topology. Take the chain stacking system as an example, such as fi...

Problems solved by technology

However, it does not fundamentally solve the problem of management channel congestion that is easily caused when the master device sends a large number of identical packets to the port.
