    Abstract

    This paper proposes two cell dispatching algorithms for the input-queuing space-memory-memory (IQ-SMM) Closnetwork to reduce out-of-sequence (OOS) for multicast traffic. The frequent connection pattern change of DSRR results in a severe OOS problem. Based on the principle of DSRR, MFDSRR is able to reduce OOS but still suffers from it under high traffic load. MFRR maintains the connection pattern separately for each input and can eliminate the in-packet OOS and thus significantly reduces the reassembly buffer size and delay.
