HYBRID ACCESS NETWORK ARCHITECTURE FOR DATACENTER BASED ON ASYNCHRONOUS OPTICAL PACKET SWITCHING

摘要：

　　A hybrid interconnected access network architecture based on asynchronous optical-packet-switching(AOPS)technology is presented for application of the datacenter.AOPS is adopted for processing burst services and enhancing switching efficiencies,and the ring-mesh hybrid interconnection can improve the datacenter scalability with survivability function.Optical switching array and all-optical tunable delay lines(AOTDLs)are used to resolve contention,to reduce system time delay and packet loss ratio(PLR)as well as to enlarge throughput.Distributed control management alleviates the pressure of computing and storing.The simulation models for PLR and time delay in the datacenter are set up,which have been approved to be efficient in the asynchronous variant self-similar traffic.And the PLR increases with increasing traffic load while decreases with the larger buffer granularity and time delay increases with increasing traffic and the larger buffer granularity.
