Congestion Avoidance with Normalized Interval of Time (CANIT) [46] Non-linear neural network congestion control based on genetic algorithm for TCP/IP networks [47] D-TCP [48] NexGen D-TCP [49] Copa [50] TCP New Reno was the most commonly implemented algorithm, [citation needed] SACK support is very common [citation needed] and is an extension ...
TCP Vegas is a TCP congestion avoidance algorithm that emphasizes packet delay, rather than packet loss, as a signal to help determine the rate at which to send packets. It was developed at the University of Arizona by Lawrence Brakmo and Larry L. Peterson and introduced in 1994.
FAST TCP (also written FastTCP) is a TCP congestion avoidance algorithm especially targeted at long-distance, high latency links, developed at the Netlab, California Institute of Technology and now being commercialized by FastSoft. FastSoft was acquired by Akamai Technologies in 2012. [1]
CUBIC is a network congestion avoidance algorithm for TCP which can achieve high bandwidth connections over networks more quickly and reliably in the face of high latency than earlier algorithms. It helps optimize long fat networks .
Networks use congestion control and congestion avoidance techniques to try to avoid collapse. These include: exponential backoff in protocols such as CSMA/CA in 802.11 and the similar CSMA/CD in the original Ethernet , window reduction in TCP , and fair queueing in devices such as routers and network switches .
When congestion is detected, the transmitter decreases the transmission rate by a multiplicative factor; for example, cut the congestion window in half after loss. The result is a saw-tooth behavior that represents the process of bandwidth probing.
In 2001, RFC 3168 was written to describe Explicit Congestion Notification (ECN), a congestion avoidance signaling mechanism. The original TCP congestion avoidance algorithm was known as TCP Tahoe, but many alternative algorithms have since been proposed (including TCP Reno, TCP Vegas, FAST TCP, TCP New Reno, and TCP Hybla).
DECbit is a TCP congestion control technique implemented in routers to avoid congestion.Its utility is to predict possible congestion and prevent it. When a router wants to signal congestion to the sender, it adds a bit in the header of packets sent.
