By analyzing the steady state throughput of TCP flows in differentiated service (DiffServ)
networks, we show that current DiffServ networks are biased in favor of those flows that have …

We propose an adaptive token bucket algorithm for achieving proportional sharing of
bandwidth among aggregate flows in differentiated service (DiffServ) networks. By observing …

The assured forwarding per hop behavior standardized by the IETF Differentiated Services
working group provides four class-based differentiated IP services. In this service, however …

This letter proposes a Markov chain based model for dynamic bandwidth allocation in
DiffServ networks. At a time-slot, the proposed Markov chain is used to predict the bandwidth …

We present a simple packet level model to show how marking at the DiffServ boundary node
and scheduling and discarding inside a DiffServ node affect the division of bandwidth …

There are two cruxes of issues identified in differentiated services (diffserv) networks: One is
TCP dynamics over Assured Services, and the other is the interaction of TCP and UDP flows …

It is a challenging issue to provide guaranteed QoS for diverse network applications while
still obtaining high network utilization in DiffServ networks. As a promising approach to …

In this paper, a comprehensive analytical model to predict the bandwidth achieved by
aggregates of TCP flows in a DiffServ network is presented. The model predicts achieved …

The current DiffServ proposal suffers from an unfair distribution of excess network bandwidth
among aggregates and also between TCP and UDP flows. To alleviate this problem, in this …

The differentiated services (DiffServ) architecture has been proposed as a scalable solution
for delivering end-to-end quality of service (QoS) guarantees over the Internet. While the …
