Abstract:
1. A transmission apparatus for use in a communication network comprising: a receive frame processing part for receiving a data frame including a priority packet to be processed by priority and a non-priority packet having a lower processing priority than said priority packet and performing receipt processing of the receive data frame; a receive packet sorting part for sorting a receive packet included in the received data frame into said priority packet and said non-priority packet by inspecting a communication protocol header provided in a protocol layer constituting said receive packet, and separately outputting said priority packet and said non-priority packet in parallel, a priority packet processing part for processing said sorted priority packet; and a non-priority packet processing part for processing said sorted non-priority packet; wherein said priority packet and said non-priority packet sorted by said receive packet sorting part are transferred in parallel to said priority packet processing part and said non-priority packet processing part, respectively; wherein said priority packet processing part and said non-priority packet processing part are independently separated from each other, and wherein said processing of said sorted priority packet and said processing of said sorted non-priority packet are performed concurrently, and wherein said priority packet sorted by said receive packet sorting part is subject to termination processing of said protocol layer with said communication protocol header being removed and the resultant priority data is transferred to said priority packet processing part, whereas said non-priority packet is transferred to said non-priority packet processing part without removing said communication protocol header.
