Van Jacobson TCPIP Header Compression is a data compression protocol described in RFC 1144 , specifically designed by Van Jacobson to improve Internet protocol suite TCPIP performance over slow serial links. Van Jacobson compression reduces the normal 40 byte TCPIP packet headers down to 3 4 bytes for the average case. It does this by saving the state of TCP connections at both ends of a link, and only sending the differences in the header fields that change. This makes a very big difference for interactive performance on low speed links, although it will not do anything about the processing delay inherent to most dialup modems. Van Jacobson Header Compression also VJ compression, or just Header Compression is an option in most versions of Point to Point Protocol PPP .

IPstack T TCP Transactional Transmission Control Protocol TCP is a variant of the TCP protocol. It is an experimental TCP extension for efficient transaction oriented request response service. It was developed to fill the gap between TCP and User Datagram Protocol UDP , by Bob Braden in 1994. Its definition can be found in RFC 1644 that obsoletes RFC 1379 . This protocol is faster than TCP and delivery reliability is comparable to that of TCP.

Principles of operation H TCP is a Packet loss loss based algorithm, using additive increase multiplicative decrease AIMD to control TCP s congestion window. It is one of many TCP congestion avoidance algorithms which seeks to increase the aggressiveness of TCP on high bandwidth delay product BDP paths, while maintaining TCP friendliness for small BDP paths. H TCP increases its aggressiveness in particular, the rate of additive increase as the time since the previous loss increases. This avoids the problem encountered by HSTCP and BIC TCP of making flows more aggressive if their windows are already large. Thus, new flows can be expected to converge to fairness faster under HTCP than HSTCP and BIC TCP. Strengths and weaknesses A side effect of increasing the rate of increase as the time since the last packet loss increases, is that flows which happen not to lose a packet when other ... more details

TCP Westwood TCPW , is a sender side only modification to TCP New Reno that is intended to better handle large bandwidth delay product paths large pipes , with potential packet loss due to transmission or other errors leaky pipes , and with dynamic load dynamic pipes . TCP Westwood relies on mining the ACK stream for information to help it better set the congestion control parameters Slow Start Threshold ssthresh , and Congestion Window cwin . In TCP Westwood, an Eligible Rate is estimated and used by the sender to update ssthresh and cwin upon loss indication, or during its Agile Probing phase, a proposed modification to the well known Slow Start phase. In addition, a scheme called Persistent Non Congestion Detection PNCD has been devised to detect persistent lack of congestion and induce an Agile Probing phase to expeditiously utilize large dynamic bandwidth. The resultant performance gains in efficiency, without undue sacrifice of fairness, friendliness, and stability have been reported in numerous papers that can be found on http www.cs.ucla.edu NRL hpi tcpw The TCP WESTWOOD Home Page . Significant efficiency gains can be obtained for large leaky dynamic pipes, while maintaining fairness.

unreferenced date April 2012 CUBIC is an implementation of Transmission Control Protocol TCP with an optimized Network congestion avoidance congestion control algorithm for high speed networks with high latency LFN Long fat network Long Fat Networks . It is a less aggressive and more systematic derivative of BIC TCP , in which the window is a cubic function of time since the last congestion event, with the inflection point set to the window prior to the event. Being a cubic function, there are two components to window growth. The first is a concave portion where the window quickly ramps up to the window size before the last congestion event. Next is the convex growth where CUBIC probes for more bandwidth, slowly at first then very rapidly. CUBIC spends a lot of time at a plateau between the concave and convex growth region which allows the network to stabilize before CUBIC begins looking for more bandwidth. Another major difference between CUBIC and standard TCP flavors is that it does not rely on the receipt of ACKs to increase the window size. CUBIC s window size is dependent only on the last congestion event. With standard TCP, flows with very short Round trip delay time RTT s will receive ACKs faster and therefore have their congestion windows grow faster than other flows with longer RTTs. CUBIC allows for more fairness between flows since the window growth is independent of RTT. CUBIC TCP is implemented and used by default in Linux kernels 2.6.19 and above.
