TCP-friendly layered multicast protocol for multimedia streaming

Abstract

Layered multicast protocol (LMP) is designed to support simultaneous and real-time multimedia content distribution to large number ofdisparate receivers across the heterogeneous Internet. However, the current layered multicast protocols (LMPs) use the techniques that do not correctly model TCP behaviour, which results in the protocols can't fairly compete with TCP. TCP-friendly layered multicast protocol (TjLMP) is designed to solve the problems with the current LMPs. It use the techniques that closely model TCP behaviour, i.e. scalable RTT estimation and 2-step loss event rate filtering. The techniques enable TjLMP to compete with TCP and get fair amount ofbandwidth share. TjLMP is evaluated using ns2 simulation and the results are compared with the other LMPs.

Telemetry Data Acquisition and Analysis in Integrated Baseband System Based on TCP/IP Protocol

“…The TCP fits into alayered protocol architecture just above a basic Internet Protocol which provides a way for the TCP to send and receive variable-length segments of information enclosed in internet datagram "envelopes" [3]. The internet datagram provides a means for addressing source and destination TCPs in different networks.…”
