ABSTRACT:
An end point controller includes two of ingress/egress port pairs. A first one of the ingress/egress ports is adapted to send and receive one of a pair of types of information packets and a second one of the ingress/egress ports is adapted to send and receive the other one of the pair of types of information packets. A controller is coupled to the two port pairs for coupling one of ingress/egress ports to an input/output port selectively in accordance with the type of the information packet on the ingress/egress ports and the availability of the end point controller to a network. One of the egress ports is directly coupled to the output port to the network if the information packet is at such port and the end point controller has been granted access to the network while other information at the pair of egress ports is buffered prior to being coupled to the output. In like fashion, the input port from the network is directly coupled to one of the ingress ports if the information packet is of the type of information packet destined for such ingress port, said port being available to transmit the packet.
