Method and system for automatically distributing VLAN (virtual local area network)

Abstract

The invention discloses a method and a system for automatically distributing a VLAN (virtual local area network). The method comprises the steps of: receiving a VLAN resource request sent by a terminal by a head end device, and sending the VLAN resource request to a VLAN resource distribution server; receiving the VLAN resource request sent by the head end device by a VLAN resource distribution server, searching a VLAN resource pool corresponding to the head end device, distributing VLAN resources according to the VLAN resource request and a configured strategy and sending VLAN configuration; and sending the VLAN configuration sent by the VLAN resource distribution server to the terminal by the head end device, and applying the VLAN configuration by the terminal. In the invention, the head end device receives the VLAN resource request sent by the terminal, and sends the VLAN resource request to the VLAN resource distribution server; and the VLAN resource distribution server distributes the VLAN resources according to the configured strategy, thereby realizing the automatic configuration of a terminal VLAN label.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a method and system for automatic VLAN assignment. Background technique [0002] EOC (Ethernet Over Cable, Ethernet cable) is a kind of IP (Internet Protocol, Internet Protocol) data transmission using Cable in HFC (Hybrid Fiber-Coaxial, a hybrid network combining optical fiber and coaxial cable) Technology is generally divided into two parts: head end and terminal. [0003] EPON (Ethernet Passive Optical Network, passive optical network) system includes OLT (Optical Line Terminal, optical cable terminal equipment), optical splitter, ONU (Optical Network Unit, optical network unit) and other components, and is widely used in last-mile access. [0004] PUPSPV (Per-User Per-Service Per-Vlan, Per-User Per-Service Per-Vlan) is a VLAN (Visual Local Area Network, virtual local area network) allocation method, which refers to the use of different VLANs for different users and different ser...

AI Technical Summary

Problems solved by technology

In the prior art, the above two label configuration methods are all completed by manual configuration. Since the location of the aggregation switch is relatively high, the number of the entire network is not too large, and the number of OLT interfaces of each aggregation switch is not too many, so the external Layer VLAN tag configuration is not very large

However, the number of head-end devices is huge, and the workload of configuring VLANs for different user terminals on each head-end device is very heavy, and the error rate during manual configuration is also high.
