TCP Optimizer A variant of the standard TCP algorithm just described, called CUBIC, is the default congestion control algorithm distributed with Linux. Here, retransmission is a mechanism used by protocols such as TCP to provide reliable communication. Congestion Control is also known as TCP Congestion control. One problem with the Tahoe algorithm is that when a segment is lost the sender side of the application may have to wait a long period of time for the timeout. The main TCP features are connection management, reliability, flow control and congestion control. Harjinder Kaur and Dr. Gurpreet Singh* CSE, GZSCCET, MRSPTU, Dabwali Road, Bathinda, Punjab, India, *Corresponding author . Access Control Tactics in Computer Networks. Historically, the D 3 algorithm came first, but we will start with D 2 TCP because it is closer in design to DCTCP and unlike D 3 does not impact the switches or make fundamental changes to TCP’s additive increase/multiplicative decrease (AIMD) scheme. Transmission Control Protocol (TCP) uses a network congestion-avoidance algorithm that includes various aspects of an additive increase/multiplicative decrease (AIMD) scheme, along with other schemes including slow start and congestion window (CWND), to achieve congestion avoidance. The TCP retransmission means resending the packets over the network that have been either lost or damaged. TCP refers to Transmission Control Protocol that uses a network congestion-avoidance algorithm. Previously, we assumed that only the receiver can dictate the sender’s window size. Congestion Control is also known as TCP Congestion control. Well-tuned networks can perform up to 10 times faster in some cases.

TCP Congestion Control Policy consists of three phases- Slow start phase, Congestion Avoidance Phase, Congestion Detection Phase. The TCP congestion control algorithm just described is often referred to as Tahoe. T5 sends a TCP SYN packet without IP DF and a window field of 31337 to a closed port. One problem with the Tahoe algorithm is that when a segment is lost the sender side of the application may have to wait a long period of time for the timeout. New Reno treats retransmission timeouts (RTO) and duplicate ACKs as packet loss just like the older Reno, Tahoe) algorithms, however it performs a fast retransmit and skips the slow start and enters "fast recovery". T6 sends a TCP ACK packet with IP DF and a window field of 32768 to a closed port. The TCP retransmission means resending the packets over the network that have been either lost or damaged. TCP tuning techniques adjust the network congestion avoidance parameters of Transmission Control Protocol (TCP) connections over high-bandwidth, high-latency networks.
