Performance Enhancement in Concurrent Multipath Transfer using Limited –Receive Buffer

M. Subramaniam, Dr. D. Manjula

Abstract


The performance of Concurrent Multipath Transfer using SCTP Multihoming (CMT) having limited-receive buffer (lim_rbuf) is analyzed. The CMT performance is studied, when a sender having limited buffer by means of receiver buffer lim_rbuf-bifurcation pattern. This is demonstrated using simulation that if three paths are used for CMT, the lower quality (i.e., higher loss rate) path degrades overall throughput of a lim_rbuf -constrained CMT association by blocking the lim_rbuf. It is substantiated that a wise buffer lim_rbuf-bifurcation pattern along with recently contrived retransmission policy can relieve some of the throughput degradation by reducing the rbuf-blocking problem. Here CMT performance is studied and discussed only in asymmetric path delays using lim_rbuf- bifurcation pattern and constrained rbuf values of 128KB, 256KB, 512KB and 1024KB. While lim_rbuf blocking can be minimized by choice of rbuf-bifurcation pattern along with recently contrived retransmission policy improves the performance of rbuf-blocking problem - a facility that is operable to only the transport layer.
