Abstract
Current assured forwarding (AF) service in differentiated services (DiffServ) networks can provide stable guarantees in throughput, but is lacking of efficient schemes in ensuring queuing delay and loss ratio. By analyzing the steady state operating point of RIO, this paper proposes two active queue management algorithms with adaptive control policy, namely ARIO-D and ARIO-L. These two algorithms can provide differentiated performance in, respectively, queuing delay and loss ratio, in addition to throughput guarantee. By deploying ARIO-D and ARIO-L, AF service can provide quantitative guarantees for multimedia traffic with multiple QoS metrics.
