In this paper, we introduce a control theoretical analysis of the closed-loop congestion
control problem in packet networks. The control theoretical approach is used in a …

High-speed communication networks are characterized by large bandwidth-delay products.
This may have an adverse impact on the stability of closed-loop congestion control …

Research on congestion-control algorithms has traditionally focused more on performance
than on robustness of the closed-loop system to changes in network conditions. As the …

There is growing interest in designing high speed routers with small buffers that store only
tens of packets. Recent studies suggest that TCP NewReno, with the addition of a pacing …

The flow/congestion control scheme of TCP is based on the sliding window mechanism. As
we demonstrate in this paper, the performance of this and other similar end-to-end flow …

The occurrence of congestion severely degrades the performance, especially in high-speed
networks with long propagation delay relative to packet transmission time. This is because it …

We discuss congestion control algorithms, using network awareness as a criterion to
categorize different approaches. The first category (” the box is black”) consists of a group of …

Congestion control is a fundamental building block in packet switching networks such as the
Internet due to the fact that communication resources are shared. It has been shown that the …

The activity in building gigabit speed networks has led many researchers to re-examine the
issue of congestion control. We describe a rate-based hop-by-hop congestion control …

This paper presents a feedback control algorithm for ATM congestion control in which ABR
source rates are throttled according to VC queue levels at intermediate nodes along the …
