Mesh network differential upgrading method and system based on PON network

By using a differential upgrade method based on PON networks, differential patch packages are generated and forward error correction coding is performed. Combined with P2P fragmented set transmission and topology-aware scheduling, the problems of large data volume and easy interruption in the firmware upgrade process in Mesh networks are solved, and efficient and reliable collaborative upgrade results are achieved.

AI Technical Summary

Technical Problem

Traditional Mesh network firmware upgrade methods suffer from problems such as large firmware package size, easy interruption of the upgrade process leading to network paralysis, and lack of efficient collaborative upgrade solutions.

Method used

A differential upgrade method based on PON network is adopted to generate differential patch packages and perform forward error correction coding. Through P2P fragmented set transmission and topology-aware scheduling strategy, intelligent node selection and error correction processing from AP are realized to ensure the efficiency and reliability of the upgrade process.

Benefits of technology

Significantly reduces the amount of data transmitted, lowers network bandwidth usage and user costs, improves upgrade success rate, reduces server pressure, ensures smooth upgrade process and anti-interference capabilities, and achieves efficient collaborative upgrades.

Abstract

The invention relates to the technical field of communication, can be applied to fiber to room (FTTR), enterprise-level fiber to room (FTTR-B) and broadband fusion terminal products, and provides a Mesh network differential upgrading method and a Mesh network differential upgrading system based on a passive optical network (PON). The method comprises the following steps: after an upgrade server receives an upgrade request, comparing new and old firmware versions, and generating a difference service pack; the upgrade server executes forward error correction coding on the differential service pack; taking the coded patch fragment set as a P2P fragment set, and uploading the P2P fragment set to a distribution network as an initial seed to wait for downloading by a main AP; the master AP downloads a complete P2P fragment set from the distribution network to become a super seed in the Mesh network so as to track the downloading progress of all slave APs in the Mesh network and an owned fragment list in real time; the slave AP requests the required P2P fragments from the optimal downloading node; and performing error correction processing on the received P2P fragment until a complete and errorless P2P fragment is obtained so as to complete firmware upgrading.
