VLAN (Virtual Local Area Network) distribution method for different terminal services

Abstract

The invention discloses a VLAN (Virtual Local Area Network) distribution method for different terminal services, belonging to the field of communication; the method comprises the following steps: (1) in a PON (Passive Optical Network) plus EOC (Ethernet Over Cable)/LAN (Local Area Network) environment, starting a QinQ at a PON port of an OLT (Optical Line Terminal) device and ending the QinQ at the port of a BRAS (Broadband Remote Access Server), namely deploying an internal layer VLAN below the PON of the OLT, simultaneously arranging an external layer VLAN at the PON, and transparently passing the external layer VLAN above the PON; (2) from the OLT to a network end-point, deploying a service VLAN; (3) planning continuous thirty internal layer VLANs for one building node; and (4) planning one service VLAN for continuous eight building nodes. By combining with technological methods such as QinQ and the like in VLAN planning to carry out reasonable extension on VLAN resources to meet use requirements of the services: through taking the external layer VLAN of the QinQ as a sub-front end identifier or an access device identifier for planning and taking the internal layer VLAN as a user or service identifier for planning, the problems of conflict, waste and the like of resource use occurred in a bidirectional access network are effectively solved, and the requirements on precise recognition and safety isolation of the services are realized. According to the VLAN distribution method for the different terminal services disclosed by the invention, the implementation steps are simple, so the method is easy for promotion and use.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a VLAN allocation method for different terminal services. Background technique [0002] EOC is a technology for IP data transmission using cables in a hybrid network combining radio and television optical fibers and coaxial cables; the PON system includes components such as OLT (optical cable terminal equipment), optical splitters, and ONU (optical network units). Applied to one-kilometer access after the group; PUPSPV is a VLAN allocation method, which refers to the use of different VLANs for different users and different services. Users and services can be more accurately distinguished and refined according to VLAN tags. achieve accurate control. [0003] With the continuous expansion of the construction scale of the two-way access network, the scientific planning and rational deployment of network logic resources become particularly important. The current VLAN planning ...

AI Technical Summary

Problems solved by technology

The current VLAN planning and deployment mode is mostly PUPSPV+PSPV mode, which is prone to conflicts and waste of resources in the two-way access network.
