Collaborative congestion control in parallel TCP flows
IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005We suggest a new congestion control scheme in parallel TCP flows and compare it with single-flow based congestion control approaches in the Internet. When a node opens multiple connections that are going to the same or nearby destinations, we can assume that there is a significant correlation of congestion events among the flows.

TCP-Real: receiver-oriented congestion control
Computer Networks, 2002We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCP-Real. The protocol allows for a measurement-based transmission strategy, which complements the "blind" increase/ decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in ...

Reproducible measurements of TCP BBR congestion control
Computer Communications, 2019Abstract The complexity of evaluating TCP congestion control has increased considerably since its initial development in the 1980s. Several congestion control algorithms following different approaches have been proposed to match the requirements of modern computer networks.

TCP congestion control algorithm for heterogeneous Internet
Journal of Network and Computer Applications, 2016The available bandwidth, round trip time (RTT) and packet loss rate can vary over many orders of magnitude, which characterizes the heterogeneity of the Internet. To cope with the heterogeneity in Internet congestion control, we propose a new TCP protocol known as INVS that contains three key components: (1) INVS employs an exponential-function-based ...

Congestion control on spurious tcp retransmission timeouts
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004Spurious TCP retransmission timeouts are a considerable problem degrading the TCP efficiency in communication over mobile 2.5G and 3G networks. They cause several unnecessary retransmissions and diminish TCP throughput. F-RTO algorithm can be used to detect spurious TCP RTOs, thus making it possible to avoid unnecessary retransmissions in such ...

On a fair congestion control scheme for TCP Vegas
IEEE Communications Letters, 2005TCP Vegas is the congestion avoidance algorithm and utilizes the bandwidth more efficiently than TCP Reno. However, it does not guarantee the fair sharing of the bandwidth among the active connections with different round-trip times. In this paper, we proposed a new TCP Vegas to provide the fairness among connections and stabilize the queue length at ...

Stability of TCP-Like Congestion Control Algorithm
2009 Second International Symposium on Computational Intelligence and Design, 2009A delayed network congestion control algorithm is a complicated dynamical nonlinear feedback system. A class of delayed TCP congestion control algorithms, TCP Vegas congestion control schemes with general description, is analyzed. The delayed systems with discrete-time are discussed, and many criteria on the stability are obtained.

Congestion Control for Mixed TCP and UDP Traffic
IEICE Transactions on Communications, 2005In this letter, we propose a protocol sensitive random early detection algorithm for active queue management to improve fairness between TCP and UDP flows and to reduce delay time with small overheads. The algorithm classifies the packets into responsive and unresponsive flows, and applies the RED algorithm individually to each classified group.

A report on recent developments in TCP congestion control
IEEE Communications Magazine, 2001This article discusses several changes to TCP's congestion control, either proposed or in progress. The changes to TCP include a limited transmit mechanism for transmitting new packets upon receipt of one or two duplicate acknowledgments, and a SACK-based mechanism for detecting and responding to unnecessary fast retransmits or retransmit timeouts ...

Comments on "congestion control in TCP/IP internetworks"
ACM SIGCOMM Computer Communication Review, 1985The article "Congestion control in IP/TCP Internetworks" by John Nagle is an excellent illustration of problems inherent in Arpanet and Milnet technology. The article describes a series of congestion related performance difficulties in a TCP/IP network at Ford Aerospace, and suggested some "cures".What in fact the article describes is what appear to be
