Abstract:
1. An end point controller for a packet switching network, such network being coupled to a node through the packet switching network, such node being adapted to transmit independently to the network two different types of information packets, and to receive such two different types of information packets from the network, such end point controller comprising: a pair of egress ports, a first one of the pair of egress ports being adapted to receive one of the pair of types of information packets and a second one of the pair of egress ports being adapted to receive the other one of the pair of types of information packets; an I/O output port connected to the network for transmitting the information packets to the network; a low latency buffer; a store and forward buffer; a multiplexer having: a first input connected to the first one of the pair of egress ports for passing information packets at the first one of the pair of egress ports to the first input through a path through the low latency buffer; a second input connected to the second one of the pair of egress ports for passing information packets at the second one of the pair of egress ports to the second input through the store and forward buffer; and a third input connected to the first one of the pair of egress ports for passing information packets at the first one of the pair of egress ports to the third input through a path by-passing the low latency buffer; wherein information packets at the first one of the pair of egress ports are coupled to the multiplexer through both the path by-passing the low latency path and the path through the low latency buffer; and a controller coupled to the pair of egress ports for coupling a selected one of the inputs to the I/O port, such one of the inputs being selected in accordance the type of the information packets on the pair of egress ports and the availability of the end point controller to the network, the third one of the multiplexer inputs being selected if an information packet received for transmission by the end point controller is on the first one of the pair of egress inputs and the end point controller has been granted access to the network.
