Fixed Point Of A TCP/RENO DiffServ Network With A Single Congested Link
White Papers The DiffServ network under consideration run TCP RENO, uses a multi-PI AQM for marking at the core and token bucket for coloring at the edges. Before proceeding with the fixed point problem, the paper describes a limitation of the current leaky...

Time-Driven Early Discard (TED) To Improve The Fairness Of TCP Congestion Control
White Papers TED is shown to improve fairness among TCP connections sharing congested links when the deadline is chosen proportional to their round trip time (RTT). TED is adaptive in limiting the throughput of only those connections that traverse congested links.

Experiences With Reducing TCP Performance Problems On ADSL
White Papers The uplink capacity of ADSL products in general does not result in ack compression unless the uplink is congested. For a single user ADSL installation this is manageable but for larger networks connected to the Internet by ADSL the rise of peer-to...

A Variable Structure Control Approach To Active Queue Management For TCP With ECN
White Papers It has been shown that the TCP connections through the congested routers can be modeled as a feedback dynamic system. By analyzing the robustness and performance of the control scheme for the nonlinear TCP/AQM model, the paper shows that the...

Dynamic Quality Adaptation Mechanisms For TCP-Friendly MPEG-4 Video Transfer
White Papers When a considerable amount of UDP traffic is injected into the Internet by distributed multimedia applications, the Internet is easily driven congested. Consequently, bandwidth available to TCP connections is oppressed and their performance...

A Rate-Based Congestion Control Scheme For Reliable Multicast Achieving TCP Fairness
White Papers So it is important to make a provision of congestion control for multicast and multicast session should share congested resources fairly with TCP session - which is called TCP fairness - in order to prevent multicast traffic from exclusively...

The Role Of Buffer Management In Controlling The Effects Of Congestion Over 10 GbE Links
White Papers DBP-sized buffers, together with RED congestion avoidance, can be used to optimize the utilization of congested links by TCP applications. This white paper describes the rationale for providing switch/routers with port buffers that are scaled to...

Stability Analysis Of Some Classes Of TCP/AQM Networks
White Papers Recently, in Misra et al.a fluid-flow model describing accurately the behavior of congested routers in TCP/AQM networks was introduced. The local stability analysis of some classes of nonlinear time-delay systems, encountered as fluid flow models...

Performance Comparison Of TFRC And TCP
White Papers In this report, the performance of TCP, TCP (a, b) and TFRC in a congested network environment are compared. TCP congestion control is the most widely used congestion control protocol and a very successful one.

Inferring Path Sharing Based On Flow Level TCP Measurements
White Papers The premise is that flows that temporally overlap on congested resources will have correlated throughputs. The paper proposes to use factor analysis to explore the correlation structure of flow class throughputs in order to hypothesize which flow...

Throughput Enhancement For Uploading TCP Flows In IEEE 802.11 Wireless LANs
White Papers They blindly assume that the number of competing stations at the MAC layer is increasing as there are more stations with TCP flows, which is not true under the congested network condition. This paper reanalyzes the relationship between MAC...

Issues In TCP Vegas
White Papers The paper has also shown that TCP Vegas could lead the network to a persistent congestion if connections start at different times when the network is congested. This paper has discussed a few issues of TCP Vegas.

Detecting Shared Congestion Of Flows Via End-to-End Measurement
White Papers However, in order for this cooperation to be effective, one must first identify the flows that are congested at the same set of resources. In this paper, we present techniques based on loss or delay observations at end-hosts to infer whether or not...
