Abstract:The link load balancing technique is proved in theory to be able to improve system availability greatly.Then the paper presents a dynamic link load balancing algorithm which can avoid the failure path.This new algorithm obtain the length of link waiting queue and response time,which helps distribute all the data traffic loads on multiple links and increase the link bandwidth usage.In addition,the availability of the current links can be managed on real time，and the current disconnected link can be shielded and the mean time to failure(MTTF)can be extended,therefore system availability greatly improves.Finally,the simulation results verify the effectiveness of this algorithm.
