Problems solved by technology

[0004] In view of the aforementioned traditional stacked network devices, the workload of the main unit is too large, resulting in poor quality and speed of network information transmission. The processing method of the Spanning Tree Protocol, in order to use the Rapid Spanning Tree Protocol to evenly distribute the work of executing the Spanning Tree Protocol and its related calculations to each slave unit, so as to effectively share the workload of the master unit, thereby improving the stacking network The network transmission performance of the system greatly improves the quality and speed of network information transmission

Embodiment Construction

[0035] The Rapid Spanning Tree Protocol referred to in the present invention, that is, IEEE802.1W, is a modified version based on the IEEE802.1D and IEEE802.1t Spanning Tree Protocols. When processing the STP, each unit of the STP can complete necessary changes according to the Rapid STP, and enable each unit to have the ability of rapid reconfiguration (reconfiguration). Traditionally, the Spanning Treepriority vector (Spanning Treepriority vector) defined in the Spanning Tree Protocol is a kind of information that can be transmitted between different STP bridges (bridges), and the information includes configuration messages such as , BPDU packet... etc., to assign (assign) the role (Port role) that should be played to each port (Ports) on each bridge. Therefore, each extension tree priority vector is basically the same It should contain the following components:

[0036] (1) The bridge identifier of the Root Bridge, called the Root Bridge ID (hereinafter referred to as Root...

Abstract

The present invention is a method in which each unit can be processed according to the rapid expanding tree protocol in a stacked network device. The bridge processing program quickly selects the port with the best tree root priority on the stacked network device, so that the port can perform the work of the expansion tree protocol and related calculations. In this way, the traditional stacked network can be The expansion tree protocol and related computing work that must be completed by the master unit in the road device are distributed to each slave unit to effectively share the workload of the master unit, thereby improving the network transmission performance of the stacked network system, and greatly improving the network performance. The quality and speed of road information transmission.

Description

technical field [0001] The invention is a method that can make each unit process according to the rapid expansion tree protocol in the stacked network device. Background technique [0002] In recent years, due to the vigorous development of the Internet world, various network devices have been continuously developed and widely used in life and work environments by all walks of life. This development trend not only accelerates the flow of information The speed and efficiency of the system also bring great convenience to people's life and work. Among the many network systems, the Stacking network system or the Chassis Layer 2 (Layer 2) / Layer 3 (Layer 3) network switching devices are the most popular in the market. Such network devices have not only been widely used in all walks of life, but may become the mainstream of future network system development. The network switching devices used in this kind of stacked network system are based on the expansion tree protocol. Constru...
