The Research And Implementation Of Self-adaptive Backup Link Scheduling Technology Based On Network Connectivity Analysis

With the fast development of computer and communication technology,communication networks have become one of the most important infrastructure.The main issue of network technology is how to ensure network" s connectivity in various cases of failure.The goal of"self-adaptive backup link scheduling technology based on network connectivity analysis"(SAST)is to design an adaptive network connectivity enhancement technology,which is based on the current IP network architecture.On one hand,this technology can monitor the connectivity of network once the network topology changed;on the other hand,it can select appropriate strategy to establish backup connections automatically.In short,SAST can be used to improve network connectivity and ensure the normal operation of communication.SAST is developed on SSFNet simulation system and Hadoop cloud(?)ting platform.both simulation and platform test results prove the functionality and efficiency of SAST.This thesis mainly includes the following aspects:(1)We analyze the existing network connectivity processing technology in depth,and propese a new network connectivity enhancement technology---SAST.(2)The design and development of SAST on SSFNet simulation platform and Hadoop cloud computing platform are introduced in detail.(3)We carried out a set of simulation tests and analyzed the results.Simulation results verified the functionality and preformance of SAST.(4)A set of tests based on Hadoop cluster were implemented and the results were verified the applicability of SAST in experimental network.
