摘要: We consider a network providing Differentiated Services (DiffServ) which allow service providers to offer different levels of Quality Service (QoS) traffic streams. focus on loss and first show that only trivial bounds could be obtained by means traditional competitive analysis. Then we introduce new approach for estimating an online policy called loss-bounded In analysis the is bounded optimal offline plus constant fraction benefit policy. relate throughput-competitive derive tight upper lower various settings DiffServ parameters using model. believe important technique can complement insight interesting results.
