“…According to [34], TCP Vegas is a congestion control algorithm that differs from traditional TCP variants like Reno by utilizing an explicit measurement of network congestion through the calculation of the round-trip time (RTT) variations. It operates on the principle that an increase in RTT indicates approaching congestion, allowing it to proactively adjust the transmission rate before packet loss occurs [35]. By employing this predictive approach, TCP Vegas aims to achieve better network utilization and reduced packet loss compared to reactive congestion control mechanisms.…”

TCP (Transmission Control Protocol), is a reliable connection oriented end-to-end protocol. It contains within itself, mechanisms for ensuring reliability by requiring the receiver to acknowledge the segments that it receives. The network is not perfect and a small percentage of packets are lost enroute, either due to network error or due to the fact that there is congestion in the network and the routers are dropping packets. TCP ensures reliability by starting a timer whenever it sends a segment. If it does not receive an acknowledgement from the receiver within the ‘time-out’ interval then it retransmits the segment. In this paper a review of various TCP is carried out. There are a number of TCP variants for application in the management of network efficiency in terms of network congestion and transmission efficiency. These variants include: - TCP Tahoe, TCP Reno, TCP New Reno, TCP Vegas, TCP SACK, TCP FACK, TCP Asym, TCP RBP, Full TCP and TCP CUBIC. Therefore, the main objective of this paper is to study the tcp types on the network performance variances. All have different features and advantages but with maximal throughput as main objective, which are termed as the clones of TCP, have been incorporated into TCP/IP protocol for handling congestion efficiently in different network scenarios.

“…The shortcomings of time-based and length-based techniques is avoided through a Time-Length-first approach. This method assembles a burst upon reaching either predefined Length or Time, whichever occurs sooner (13) . Extended-Timer-Based assembly algorithm and Fixed-Time-Min-Length assembly algorithm are the efficient versions of Time/Length hybrid approach (14,15) .…”

Background: Optical transport has emerged as a candidate solution to cope with the rising data transmission challenges of enormously evolving data. In Optical Burst Switching (OBS) networks, determining an adaptive burst size is a difficult task that must be performed efficiently during burst assembling. Methods: This research proposes a hybrid burst assembly algorithm that determines the optimal burst size during the burst creation time. The proposed algorithm uses the Transition Count Number (TCN) based method to maintain the optimal burst size when the incoming traffic is unpredictable. The efficiency of the proposed approach is investigated in terms of queuing delay, burst utilization, burst size, and burst size consistency. Findings: Three types of traffic variations (H = 0.5, H = 0.6, and H = 0.7) are imposed to evaluate the performance of the proposed burst assembly approach. As compared to the E-hybrid (time/length) strategy, the research outcomes demonstrate a 13.15% reduction in average queuing latency and a 21.26% improvement in average burst utilization. Novelty: A new burst assembly approach (hybrid burst assembly) has been proposed for OBS networks. Keywords: Burst assembly, Optical Burst Switching (OBS), burstification, burst consistency

“…Such extensions focus on the variables such as congestion window, throughput, packet loss, RTT and many others. TCP VEGAS [8] is one of the famous extensions of TCP with new congestion control strategy. To estimate the pace at which to transfer packets while keeping the congestion window normal and not overloaded, the TCP VEGAS congestion avoidance algorithm emphasizes packet delay as a signal rather than packet loss.…”

Mobile Ad hoc Networks (MANET) are a collection of mobiles and smart devices that communicate using wireless links. These types of networks are growing at the best speed and being used at a large scale than before ever because of their high availability and mobility. As the usage scale of MANET devices has been increasing, the challenges have also increased for example the proper delivery of data or information to every mobile node. Traditionally, transmission control protocol(TCP) is used for delivery but it does not fit in all scenarios due to some of its limitations such as network congestion and quick recovery in case of link failure. In this, a comparative analysis of TCP is performed with the stream control transmission protocol (SCTP) and a TCP variant called TCP VEGAS. A number of ad hoc Scenarios are proposed with varying numbers of mobile nodes,i.e 11,21, and 31. The results obtained indicate that SCTP outperforms TCP and VEGAS in throughput. The packet lifetime while using SCTP is also small i.e 0.19 seconds. The link utilization of SCTP is better than TCP and VEGAS. However, TCP increases its link utilization than VEGAS for the nodes in MANET of large delay.
