However, in contrast with conventional TCP, which cannot distinguish between random errors and congestion loss, TCP-Westwood performance is also not sensitive to random errors.
Enhancing TCP to reliably handle loss, minimize errors, manage congestion and go fast in very high-speed environments are ongoing areas of research and standards development.
The service, founded by CEO Kolton Andrus, who designed Netflix's failure injection service and worked with CTO Matthew Fornaciari while at Amazon, is designed to throw a monkey wrench into any application, simulating faults like storage errors, database congestion and sudden spikes in latency.
This research program has produced a myriad of specific algorithms and protocols to solve such problems as error recovery, congestion control, routing, multicast, and quality-of service.
Second, by referring to power and bandwidth limited access scenarios, we develop a traffic analysis of the underlying IP-over-wireless pipes that allows us to analyze the effects of both fading-induced errors and congestion-induced packet's losses on the end-to-end performance of the proposed scheduler.
As described in Section 2, TCP uses the RTT estimates to compute its retransmission time-out (RTO) timer [3], which is one of the main timers involved in TCP's error and congestion control.
The results of the quantitative evaluation of the model are presented in Fig. 3. Shown is the relative error of congestion for each section of road for a simulation run without any traffic jam avoidance.
Overall, the results show that the proposed scheme has a number of key advantages compared to conventional TCP, including a more efficient treatment of frequent transmission losses, a faster reaction to corruption losses, and the ability to distinguish between congestion errors and transmission errors and to take appropriate remedial action.
The ATCP [27] is a sender-side solution that addresses the problems of route failure, high bit error rate and congestion.
TCP bases its error, flow, and congestion control functions on the estimated RTT instead of relying on feedback from the network.
