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

Abstract

The invention discloses a message forwarding method and device based on extended OMCI under FTTR networking, and relates to the technical field of FTTR networking. The method comprises the following steps: carrying out expansion setting on an existing OMCI protocol to enable the existing OMCI 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 OMCI protocol; the main gateway generates an OMCI 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 OMCI message routing forwarding table, and forwards the message out. According to the method, the problem of on-demand communication of the sub-gateway based on the OMCI 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 present invention relates to the technical field of FTTR networking, specifically a message forwarding method and device based on extended OMCI under FTTR networking. Background technique [0002] FTTR (Fiber to The Room, fiber to the room) is a new coverage mode for home and SOHO office networks in the Gigabit era. It is the basis for FTTB (Fiber to the building in the 10 Mbit era) and FTTH (Fiber to the home in the 100 Mbit era). On the Internet, the optical fiber layout is further extended to every room or office, so that every room or office can reach Gigabit optical fiber network speed, realizing a new networking solution with full Wi-Fi 6 Gigabit coverage in the whole house. [0003] At present, the FTTR network can use GPON (Gigabit Passive Optical Network) optical fiber networking, with multiple sub-gateways connected to one main gateway, and the FTTR network continues to use the traditional GPON OMCI (ONU Management and Control Interface o...

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.
