TRANSPORT LAYER LOAD BALANCING IN FCS NETWORKS

The Stream Control Transmission Protocol (SCTP) allows for end-to-end load balancing in FCS networks to be per- formed at the transport layer, through repeated changeover. We present a problem in the current SCTP (RFC2960) speci- cation that results in unnecessary retransmissions and ìTCP- unfriendlyî growth of the sender's congestion window during certain changeover conditions. We r st illustrate the problem using an example scenario. We then briey describe the pro- posed solutions for problem and our future direction.
