Power fiber-to-the-home bandwidth distribution method and device

Abstract

The invention provides a power optical fiber to the home bandwidth distribution method and device, belonging to the technical field of electric power. The method includes: in the current polling period, based on the dynamic bandwidth scheduling flow table, matching the different service requests of each ONU with the flow table items one by one, so as to obtain the priority of each ONU service request and the bandwidth required for allocating bandwidth. Preset algorithm: according to the priority order of each ONU service request and the preset algorithm required by each ONU service request, bandwidth is allocated to each ONU service request in turn. Because the traditional single DBA algorithm is not used, but based on the analysis of the power fiber-to-the-home business requirements, different DBA algorithms are used for different services, and a business priority strategy for the comprehensive scheduling of user power and Internet services is proposed. , to achieve bandwidth allocation, thereby ensuring priority scheduling of high-priority services and ensuring real-time performance.

Description

technical field [0001] The present invention relates to the field of electric power technology, and more specifically, relates to a method and device for allocating power fiber-to-the-home bandwidth. Background technique [0002] Power fiber-to-the-home refers to the use of optical fiber composite low-voltage cables to lay optical fibers along with low-voltage power lines in the low-voltage communication access network to realize meter-to-home, and cooperate with passive optical network technology to carry power information collection and intelligent power two-way interaction. Triple play" and other services. Promoting the development of power fiber-to-the-home projects and coordinating the deployment of network infrastructure that deeply integrates power grids and communication networks has far-reaching significance for improving the energy Internet information communication system, realizing co-cable transmission, and co-construction and sharing. [0003] The main functio...
