Message forwarding method and device based on extended OAM under FTTR networking

Abstract

The invention discloses a message forwarding method and device based on extended OAM under FTTR networking, and relates to the technical field of FTTR networking. The method comprises the following steps: performing extension setting on an existing OAM protocol to enable the existing OAM protocol to support a message subscription type and have a function of identifying a message; when a certain sub-gateway pays attention to a certain message, a subscription message is sent to the main gateway through the expanded OAM protocol; the main gateway generates an OAM (Operation Administration and Maintenance) message routing forwarding table according to the subscription message, wherein the table is used for recording an association relationship between the subscriber and the subscribed message; when a certain sub-gateway generates a message, sending a published message to the main gateway; and the main gateway finds out all subscribers needing to be forwarded according to the OAM message routing forwarding table, and forwards the message out. According to the method, the problem of on-demand communication of the sub-gateways based on OAM in the FTTR networking environment can be solved, the forwarding quantity of the main gateway can be reduced to a certain extent, the forwarding efficiency is improved, and the actual application requirement is met.

Description

technical field [0001] The invention relates to the technical field of FTTR networking, in particular to a message forwarding method and device based on extended OAM under FTTR networking. Background technique [0002] FTTR (Fiber to The Room) is a new coverage model for home and SOHO office networks in the Gigabit era. Then, the optical fiber layout is further derived to each room or office, so that each room or office can reach the Gigabit fiber network speed, and realize a new networking solution with full Wi-Fi 6 Gigabit coverage in the whole house. [0003] At present, the FTTR network can use EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) fiber networking, a main gateway has multiple sub-gateways, and the FTTR network uses the traditional EPON OAM (Optical Network Unit Management Control Interface) Managed by the management agreement. However, because the OAM protocol is a master-slave protocol, it only supports the management between the m...

Problems solved by technology

[0005] Question 1. When the message A of the sub-gateway of the living room is generated, it is not clear which other sub-gateways should be sent to, and the on-demand forwarding of the message cannot be realized;

[0006] Question 2. The same message A is sent to different destinations (for example, to figure 1 In the master-bedroom sub-gateway and the guest-bedroom sub-gateway), message A needs to be sent repeatedly through the living room sub-gateway, and the sending efficiency is low; moreover, message A is transmitted many times in the network, and redundant information occupies bandwidth

[0007] Therefore, how to solve the problems of inability to quickly forward messages between multiple sub-gateways in an FTTR networking environment, low message forwarding efficiency, and large bandwidth occupation has become an urgent matter for those skilled in the art.
