Abstract
Stream Control Transmission Protocol (SCTP) is a newly general-purpose transport layer protocol, which contains advantages of both TCP and UDP, providing some new features such as multi-streaming and multi-homing. PR-SCTP is an extension to enable the partial reliable service in SCTP. In this thesis, we propose a new multi-layer transport architecture which combines multi-streaming of SCTP, partial reliable service of PR-SCTP and scalable audio coding technique to still maintain reliable audio data transmission even under poor network conditions. Two different reliability definition schemes, k_XMIT and Timed, are also used to evaluate the performance of this proposed architecture. Finally, we implement it on the NS-2 network simulator and it is proved by simulation results that Timed reliability scheme can guarantee more robust real-time data transmission and get more reliable quality at the receiver side. The most important advantage of this approach is that it causes nearly no delay during a transmission session. So it can be a practical solution for real-time applications.
