A method for expanding the communication protocol of pon local area network group based on vxlan technology

Abstract

A method for expanding the communication protocol of a PON local area network group based on VXLAN technology. The virtual service interface created on the OLT port is responsible for assembling the communication protocol for expanding the PON local area network group based on VXLAN technology, and its content is carried in the TCP / UDP payload data segment. ;The Version field is agreed to be 0x1, and the Protocol field is agreed to the communication type of the payload; the Destination Vlanid and Source VlanId fields are agreed to be the TAG attribute of the L2 link data of the service data; the FLAG field is agreed to the TAG attribute of the L2 link data of the service data The operation flag allows the configuration of VLAN TAG; the TTL field is 1, and the value of the virtual service interface is set to zero after the communication forwarding is completed, and forwarding is prohibited when the agreed TTL is 0. The invention seamlessly realizes the cross-region and cross-network local area network group, and has strong compatibility.

Description

technical field [0001] The invention relates to the field of PON local area network scale expansion, in particular to a method for contracting a communication protocol for expanding a PON local area network group based on VXLAN technology. Background technique [0002] With the continuous popularization of my country's broadband strategy, the operation of FTTH access network has achieved large-scale commercial use in my country. Most of the business applications of FTTH LAN are limited to the scale and structure of the local network. Cross-regional and cross-network FTTH local area networks are still There are bottlenecks in development. [0003] The promotion of SDN business and virtualization business demand has put forward higher requirements for cross-regional and cross-network LAN business. The natural L2 layer network forwarding characteristics of PON can best match the expansion needs of this new type of business. And it can minimize the possible technical and plannin...
