Networks often evolve to provide a host with multiple access points to the Internet. In this paper, we propose a transport layer load distribution mechanism utilizing the multiple network interfaces simultaneously. We specifically propose an extension of Stream Control Transmission Protocol (SCTP)¡¡to have load sharing over multiple network interfaces. We named the particular service provided by the proposed load sharing mechanism to be LS (Load Sharing)¡¡mode service. LS mode service is based on the following four key elements: (i) the separation of flow control and congestion control, (¥¢) congestion window based striping, (¥£) redundant packet retransmission for fast packet loss recovery, (¥¤) a novel mechanism to keep track of the receiver window size with the SACKs even if they arrive out-of-order. Through simulations, it is shown that the proposed LS mode service can aggregate the bandwidth of multiple paths almost ideally despite of the disparity in their bandwidth. When a path with a delay of 100% greater is utilized as the second path, the throughput is enhanced about 20%.
