Fairness and delay/loss study of an end-to-end bandwidth regulation scheme

The variety and heterogeneity of different approaches for Quality of Service (QoS) support on different protocol layers result in the need of a solution with end-to-end overview and regulation of dataflows in a network. Previously we proposed the concept of ROBIN (regulation of bandwidth in intra-networks) to regulate the sending bandwidth of data flows in heterogeneous campus networks by determining bottlenecks and possible rate limitations with a global knowledge of the network state based on the end-to-end operation of the mechanism. This paper presents latest results of a simulation-based performance analysis studying the throughput fairness of an enhanced version of ROBIN and evaluating the impact of the bandwidth regulation on delays and packet losses in the network.
