Problems solved by technology

[0004] The purpose of the present invention is to solve the disadvantages that the setting of VLAN in the existing VLAN access method depends on the configuration of the administrator, and the maintenance workload is large for the change of the network connection and the change of the VLAN setting. Switches with ingress function can automatically join VLANs by identifying the vid (VLAN Identifier) ​​in the 802.1Q protocol identifier Tag carried by the data packets, and can flexibly switch between different VLAN groups as needed to meet the networking requirements. Reduce manual configuration, and have better adaptability to network connection changes, VLAN setting changes, etc.

Embodiment Construction

[0020] Adaptive VLAN technology is realized on the basis of existing VLAN technology. By adding this function to the switch, the switch can flexibly join any currently existing VLAN according to the VLAN attribute (the value of vid in the VLAN Tag label) of the data packet received by the port, and can join in different time periods as needed Different VLAN groups can be switched freely.

[0021] The specific implementation steps are described as follows:

[0022] figure 1 It is a schematic diagram of the switching equipment system framework. The whole system is divided into five layers of modules. The underlying hardware includes CPU and switching chips. The second layer is the embedded operating system (RTOS), which provides the operating platform for the system software. The third layer is the driver module. Read and write hardware chip registers, VLAN tables and other functions. The fourth layer is the protocol and functional modules, which realize the protocols and rela...

Abstract

This invention relates to Ethernet cut-over net virtual LAN cut-over technology including port and 802.1 Q protocol to realize VLAN automatic joining and flexible switch via VLAN ID in virtual LAN tag. This invented method is to set up adaptive VLAN submodule in the equipment soft exchange protocol and function module in which the adaptive VLANN submodule can be distributed into following tasks: interrupting detection task, main process task, ageing process task. Since VLAN ID in tag is applied for automatic joining, cancel ageing, switch in the Ethernet exchange equipment, this method reduces network management manual arrangement need in ordinary VLAN.

Description

technical field [0001] The invention relates to a virtual local area network access technology of an Ethernet access network. It is a virtual local area network access technology that replaces cumbersome network management configuration with real-time software automatic configuration, has good adaptability to network changes, and does not require complicated network management configuration. Background technique [0002] Virtual local area network VLAN (Vitrual Local Area Network) is a new technology developed in the field of computer and communication in recent years, and it shows great effect and potential in improving network performance and manageability. But its most attractive advantages are its flexibility and effective control over broadcast domains, and the ability to securely isolate groups of users. [0003] There are many ways to divide VLANs, and the more commonly used method on Layer 2 devices is based on the mixed method of port port and 802.1Q protocol. The...
