| Popis: | 95 SCTP(Stream Control Transmission Protocol), a new fourth layer transport protocol, was proposed by the SIGTRAN Working Group of the IETF(Internet Engineering Task Force). The protocol is a connection-oriented and reliable transport service. It also supports multi-homing and multi-streaming mechanisms and can improve the transmission efficiency and enhance the security of traditional TCP. In this thesis we will focus on the congestion control for TCP (Transmission Control Protocol) (Tahoe, NewReno, SACK) and SCTP(SCTP, NewReno) and will compare the performance issue on delivery. We use the NS-2(Network Simulator-Version 2), a network simulation software, to simulate several scenarios of packet loss and congestion window size. The number of packets received, throughput and distribution of packet loss was simulated under two fourth layer transport protocol existing at the same time. The simulation results shows that the design of congestion control of SCTP is better than using TCP. The SCTP can not only reduce the probability of packet loss, but also improve the performance of delivery than TCP while face the suffering of multiple packet loss. |
