A method of multi-data service comprehensive networking based on vlan division and application

Abstract

The invention relates to the technical field of comprehensive networking, and discloses a method for comprehensive networking of multi-data services based on VLAN division. It specifically includes the following process: Step 1. Dynamically divide the ports for simultaneous communication into the same virtual local area network inside the router, and separate the different data for simultaneous communication; Step 2. Assign ports to corresponding virtual local area networks on the Layer 2 switch local area network. The technical scheme of the present invention not only adopts the multicast VLAN division in the router, but also divides the port VLAN inside the switch, and isolates the AP port in the later stage. Not only the scheme is simple, the cost is saved, the bandwidth is used reasonably, and Effectively reduce and control the impact and impact of broadcasting. During the operation of the entire network, even if there is a device failure, it will not affect the entire network, and can realize the effective distribution of various data services.

Description

technical field [0001] The invention relates to the technical field of comprehensive networking, in particular to a multi-data service comprehensive networking method based on VLAN division. Background technique [0002] Broadcasting plays a very important role in the network, such as discovering new devices, adjusting network paths, leasing IP addresses, etc. Many network protocols use broadcasting, such as. However, as the number of computers in the network increases, the number of broadcast packets will also increase sharply. When the number of broadcast packets accounts for 30% of the total communication, the transmission efficiency of the network will drop significantly. Therefore, when the number of computers in the local area network reaches a certain number (usually limited to 150~200), the network is usually separated by dividing VLANs, and a large broadcast domain is divided into several small broadcast domains. In order to reduce the damage that broadcasting may ...

[0014] Second, if you want to divide two or more VLANs on a switch, then the switch must also support the VLAN division function

Although different manufacturers implement the same international standards and protocols, they also adopt a large number of unique protocols and technologies (such as Cisco's ISL). Therefore, when implementing VLAN relay between switches, many difficulties will be encountered and many inexplicable problems will arise. communication failure
