I-TCP: Indirect TCP for mobile hosts

by Ajay Bakre, B. R. Badrinath , 1995
"... Abstract — IP-based solutions to accommodate mobile hosts within existing internetworks do not address the distinctive features of wireless mobile computing. IP-based transport protocols thus suffer from poor performance when a mobile host communicates with a host on the fixed network. This is cause ..."
Abstract - Cited by 614 (7 self) - Add to MetaCart
. This is caused by frequent disruptions in network layer connectivity due to — i) mobility and ii) unreliable nature of the wireless link. We describe the design and implementation of I-TCP, which is an indirect transport layer protocol for mobile hosts. I-TCP utilizes the resources of Mobility Support Routers

A comparison of mechanisms for improving TCP performance over wireless links

by Hari Balakrishnan, Venkata N. Padmanabhan, Srinivasan Seshan, Randy H. Katz - IEEE/ACM TRANSACTIONS ON NETWORKING , 1997
"... Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit errors and handoffs. TCP responds to all losses by i ..."

The Performance of TCP/IP for Networks with High Bandwidth-Delay Products and Random Loss.

by Member, IEEE T V Lakshman , Senior Member, IEEE Upamanyu Madhow - IEEE/ACM Trans. Networking, , 1997
"... Abstract-This paper examines the performance of TCP/IP, the Internet data transport protocol, over wide-area networks (WANs) in which data traffic could coexist with real-time traffic such as voice and video. Specifically, we attempt to develop a basic understanding, using analysis and simulation, ..."

Improving TCP/IP performance over wireless networks

by Hari Balakrishnan, Srinivasan Seshan, Elan Amir, Randy H. Katz - IN PROCEEDINGS, 1ST ACM CONF. ON MOBILE COMPUTING AND NETWORKING , 1995
"... TCP is a reliable transport protocol tuned to perform well in traditional networks made up of links with low bit-error rates. Networks with higher bit-error rates, such as those with wireless links and mobile hosts, violate many of the assumptions made by TCP, causing degraded end-to-end performance ..."

Equation-based congestion control for unicast applications

by Sally Floyd , Mark Handley , Jitendra Padhye , Jörg Widmer - SIGCOMM '00 , 2000
"... This paper proposes a mechanism for equation-based congestion control for unicast traffic. Most best-effort traffic in the current Internet is well-served by the dominant transport protocol, TCP. However, traffic such as best-effort unicast streaming multimedia could find use for a TCP-friendly cong ..."

Random Early Detection Gateways for Congestion Avoidance.

by Sally Floyd , Van Jacobson - IEEELACM Transactions on Networking, , 1993
"... Abstract-This paper presents Random Early Detection (RED) gateways for congestion avoidance in packet-switched networks. The gateway detects incipient congestion by computing the average queue size. The gateway could notify connections of congestion either by dropping packets arriving at the gatewa ..."
Abstract - Cited by 2716 (31 self) - Add to MetaCart
-speed ne!works with connections with large delay bandwidth products. gateways are likely to be designed with correspondingly large maximum queues to acccomodate transient congestion. In the current Internet, the TCP transport protocol detects congestion only after a packet has been dropped al the gateway

A Proposal to add Explicit Congestion Notification (ECN) to IP

by K. Ramakrishnan, S. Floyd , 1999
"... This note describes a proposed addition of ECN (Explicit Congestion Notification) to IP. TCP is currently the dominant transport protocol used in the Internet. We begin by describing TCP's use of packet drops as an indication of congestion. Next we argue that with the addition of active queue m ..."

An Analysis of TCP Processing Overhead

by David D. Clark, Van Jacobson, John Romkey, Howard Salwen - IEEE Communications Magazine , 1989
"... networks, have been getting faster, perceived throughput at the application has not always increased accordingly. Various performance bottlenecks have been encountered, each of which has to be analyzed and corrected. One aspect of networking often suspected of contributing to low throughput is the t ..."
Abstract - Cited by 348 (0 self) - Add to MetaCart
preliminary examination suggested to us that other aspects of networking may be a more serious source of overhead. To test this proposition, a detailed study was made of a popular transport protocol, Transmission Control Protocol (TCP) [I]. This paper provides results of that
