摘要： A multi-layer class identifying communication apparatus, includes an input interface connected to input communication lines; a switch circuit; and an output interface connected to output communication lines. The input interface comprises an allocating section which determines a class identifier indicative of one of classes to which an IP packet belongs, from header data of the IP packet received through one of the input communication lines, and allocates an IP-QOS (Internet-Protocol-Quality-of-Service) code to the IP packet. The switch circuit selects one of the output communication lines based on a destination address of the IP packet, such that the IP packet is outputted from the output interface to the selected output communication output interface.

摘要： An application monitor apparatus is provided that enables feedback to be sent to a transmitting terminal without relay processing of application data in the application layer. A packet transmission decision unit outputs to an application monitor unit and a packet transmitting unit only packets for which transmission is authorized by both the application monitor unit and the packet transmitting unit. When monitoring processing of the application monitor unit is slower than the rate of receiving packets at a packet receiving unit, the packet transmission decision unit sends feedback to the packet receiving unit to delay the transmission of packets.

摘要： A packet switch scheduling apparatus in a packet communication apparatus is disclosed. Output schedulers select respective input lines, which are to be connected to a crossbar switch, for respective output lines. If previously selected input lines overlap each other, input schedulers select respective output lines for respective input lines, and output canceling information to those output schedulers which correspond to overlapping output lines that have not been selected. When the output schedulers are supplied with the canceling information, the output schedulers increments the value of request counters for the input lines corresponding to the input schedulers which have output the canceling information.
