ABSTRACT:
Real-time hardware primitives are added to packet switches to provide efficient support for inward multicasting. The lookup table used for routing is extended by adding additional opcode and operand fields into the routing table and by including ALU circuitry to process these fields and corresponding fields in the arriving cells. Memory word widths can be extended with minimal additional chip count and the ALU can be a small addition in a header processing VLSI, thereby giving only a modest increase in complexity. By including real-time processing in the switch it is possible to solve the ACK implosion problem associated with high-speed reliable multicasting transport protocols. By keeping the primitives as general as possible, other applications can benefit as well from these real-time primitives.
