A Dynamic Granularity Control Algorithm for Avoiding TCP Deadlocks over Congested ATM Networks

Dynamic Analysis of Congested TCP Networks

The objective of this paper is to study the small-signal stability of congested TCP networks. The starting point for this analysis is a fluid model describing the interaction of TCP-controlled traffic with congested routers. Assuming integral action in the active queue management scheme, we compute the network’s equilibrium point about which we determine the network’s small-signal dynamics. Spe...

Buffer reservation for TCP over ATM networks

Transmission Control Protocol (TCP) has already been a widely used protocol in many networks. Recent studies show that the performance of TCP over ATM networks is severely degraded. In this paper, we propose to apply the buffer reservation technique on TCP traffic over ATM networks. While the ATM block transfer (ABT) method (Boyer, 1992) is to reserve bandwidth for bursts of cells, our proposed...

End-to-End TCP Congestion Control over ATM Networks

It is well documented that the eeective throughput of TCP can suuer on plain ATM networks. Several research eeorts have aimed at developing additions to ATM networks like Early Packet Discard that avoid TCP throughput degradation. This paper instead investigates improvements to TCP that allow it to perform well on ATM networks without switch-level enhancements, thus avoiding additional complexi...

Dynamics of TCP in congested ATM multiplexers

In this paper we investigate the dynamic behavior of multiplexer queues for TCP traac in simple ATM networks. Our results are based on theoretical investigations which are proved by simulations. We propose a cell based queue length evaluation for TCP traac over ATM using service c ategorie UBR. In case of cell losses at the ATM multiplexer we estimate packet loss probabilities and discuss the i...
