Improvement of TCP Congestion Control in the Internet
Wei Li · Journal of Guangzhou Maritime College · 2003
With the rapid development of multimedia technology, it is time to improve curre nt Congestion Control. Rather than the traditional method, ABC (Appropriate Byte Counting) suggests basing the increase on the number of previously unacknowledg ed bytes each ACK(Acknowledgement) covers. This change improves the performanc e of TCP, as well as closes a security hole TCP receivers can use to induce the sender to increasing the sending rate too rapidly. Besides, increasing the TCP i nitial window to three packets (or 4380 bytes) helps to improve perceived perfor mance. To improve the performance, CM (congestion manager) is designed to allow application to easily adapt to network congestion and enable proper congestion c ontrol.
