In optical burst switching(OBS) networks,to efficiently resolve the often occurring burst contention,one scheme,adaptive multi-reachability routing with load balancing(AMR-LB),is proposed,which consists of on-demand multi-reachability routing and network-wide adaptive load distribution.Firstly,the scheme decided the on-demand multi-reachability paths for every traffic flow according to its input load and current network traffic loading status.Then,it adaptively adjusted the distribution proporti...
