Modified RTO Mechanism based on TCP/IP in Heterogeneous networks
Jiang Jian-gu · Microcomputer Information · 2009
TCP/IP is the prevalent, reliable transport control protocol. It is designed for wired network. However, when it is used in heterogeneous networks, TCP performance will degrade, especially for timing mechanism. In order to improve the TCP performance in heterogeneous networks, this paper proposes a modified TCP timing mechanism and its performance are investigated through simulations. Comparing with tradition timing mechanism, spurious timeout will be avoided; the retransmit probability will be decreased. In addition, the improved timing mechanism is obtained through a little modification at the sender side, so it can be easily developed.
