TCP dynamics and congestion control on asymmetric lines∗
نویسندگان
چکیده
A growing number of network computers are connected to the Internet through asymmetric connections such as ADSL, CableNet, Satellite link and other broadband solutions. However, the asymmetric nature of such connections may have significant impact on the performance of TCP transmission as upstream bandwidth can be easily overloaded. In this situation TCP’s selfclocking mechanism may be misled when TCP ACK packets are delayed due to the congested upstream link that will result degradation in TCP throughput. Purpose of the present letter is to show the effect of asymmetric physical lines on TCP dynamics based on our empirical measurement results. Therefore, we addressed the evaluation of alternative TCP congestion control mechanisms as well.

TCP-Real: receiver-oriented congestion control
We introduce a receiver-oriented approach to congestion control, demonstrated by an experimental protocol, TCPReal. The protocol allows for a measurement-based transmission strategy, which complements the ‘‘blind’’ increase/ decrease window adjustments. Owing to its design, the protocol displays an inherent property to produce comprehensive dynamics in heterogeneous environments with wired or w...

Over the years, Transmission Control Protocol (TCP) in the Internet protocol (IP) suite has become the most widely used form of networking between computers. With the recent developments in high-speed networking and applications that use TCP, performance issues in TCP are of increasing interest and importance. The performance (e.g. throughput, number of dropped packets, etc.) during the start-u...
