Efficient Bandwidth Estimation Management for VOIP Concurrent Multipath Transfer
Concurrent multipath transfer distributes incoming traffic simultaneously between several paths to maximize network resource utilization and to improve quality of service. Voices over IP real time application is more sensitive to delay and requires bandwidth guarantee. In this paper, efficient bandwidth estimation management for VoIP concurrent multipath transfer is proposed. The proposed technique estimates the bandwidth of each path from a group and selects multiple paths from SCTP multi-homing association to transmit VoIP traffic with assured bandwidth guarantees. Simulation results are reported using Ns2 network simulator to show the efficiency of the proposed system.
