The chaotic nature of TCP congestion control
Proceedings IEEE INFOCOM 2000. Conference on Computer Communications. Nineteenth Annual Joint Conference of the IEEE Computer and Communications Societies (Cat. No.00CH37064), 2002In this paper we demonstrate how TCP congestion control can show chaotic behavior. We demonstrate the major features of chaotic systems in TCP/IP networks with examples. These features include unpredictability, extreme sensitivity to initial conditions and odd periodicity.

A robust controller for the TCP congestion window
2008 IEEE Symposium on Computers and Communications, 2008In this paper a robust active queue management (AQM) for TCP flows is designed. We synthesized a robust controller by using the Hinfin control based on weight method. This was done by defining two weights W1(s) and W2(s); the first taking account of the desired performances and the second insuring the robustness of the controller to the model ...

Extending TCP congestion control to multicast
Computer Networks, 2007This paper proposes a new single-rate multicast congestion control scheme named PGMTCC, which has been implemented and investigated in PGM. The primary idea of PGMTCC is to extend Sack TCP congestion control mechanism to multicast in order to make multicast perform almost the same as Sack TCP under all kinds of network conditions. To achieve this goal,

Scalable TCP congestion control
Proceedings IEEE INFOCOM 2000. Conference on Computer Communications. Nineteenth Annual Joint Conference of the IEEE Computer and Communications Societies (Cat. No.00CH37064), 2002The packet losses imposed by IP networks can cause long and erratic recovery delays, since senders must often use conservative loss detection and retransmission mechanisms. This paper proposes a model to explain and predict loss rates for TCP traffic. Based on that model, the paper describes a new router buffering algorithm, flow-proportional queuing ...

TCP Inigo: Ambidextrous Congestion Control
2016 25th International Conference on Computer Communication and Networks (ICCCN), 2016No one likes waiting in traffic, whether on a road or on a computer network. Stuttering audio, slow interactive feedback, and untimely pauses in video annoy everyone and cost businesses sales and productivity. An ideal network should (1) minimize latency, (2) maximize bandwidth, (3) share resources according to a desired policy, (4) enable incremental ...

Congestion control in IP/TCP internetworks
ACM SIGCOMM Computer Communication Review, 1984Congestion control is a recognized problem in complex networks. We have discovered that the Department of Defense's Internet Protocol (IP), a pure datagram protocol, and Transmission Control Protocol (TCP), a transport layer protocol, when used together, are subject to unusual congestion problems caused by interactions between the transport and ...

Fuzzy TCP: Optimizing TCP Congestion Control
2006 Asia-Pacific Conference on Communications, 2006Efficient implementation of TCP for the Internet requires a precise determination of congestion window by the source TCP agent. This paper proposes a fuzzy implementation of TCP (Fuzzy TCP), instead of current slow-start/congestion avoidance approach for efficiently determining size of the congestion window at each time a new acknowledgement receives ...

Some Improvements of TCP Congestion Control
2003Many TCP enhanced versions, such as NewReno, SACK, FACK, and Rate-Halving, were proposed to estimate the more accurate number of the outstanding packets during fast recovery phase. In this paper, we focus on the modifications in slow-start and congestion avoidance phases.
