摘要： A packet communication system of the present invention has first mode, second mode and third mode to apply to input packets. The first mode is a mode that decides priority of the packet by at least one of the address information and the application information, the second mode is a mode that decides priority of the packet by the DS value, the third mode is a mode that decides rewrite the DS value by at least one of the address information and the application information. A control unit of the packet communication system switches a mode to apply an input packet of the first mode, the second mode and the third mode based on the packet header information of the input packet.

摘要： A network relaying apparatus and method for routing and transferring packets at high speed. A transfer engine stores the packets received through a network interface in a packet buffer, and stores the header information in a header RAM. A search engine searches the transfer control information including the transfer destination information and the action information in accordance with the header information, and writes it in the header RAM. The transfer engine produces an output packet based on the information stored in the packet buffer and the header RAM and outputs it to the transfer destination. A switch switches the output packet to the routing process of the destination. The transfer engine executes the receiving process and the transmission process, and the search engine executes the input search process and the output search process. Each of these processes is executed by pipelining control using a required table independently.

摘要： When a packet arrives at a shaping unit 500, a discard control unit 510 judges whether to “store” or “discard” the arrived packet. Packets judged to be “stored” are stored into a packet storage FIFO buffer 520 and sent out within a transmission bandwidth greater than the total sum of user-by-user minimum bandwidths. A bandwidth check unit 600 checks bandwidth per user and judges packets that fall within the bandwidth to be high priority packets and packets that fall outside the bandwidth to be low priority packets. If a large quantity of packets are stored into the packet storage FIFO buffer 520, the discard control unit 510 determines that low priority packets are exclusively “discarded,” thus securing high priority packets from being discarded. Thereby, the shaping unit 500 ensures proper packet transmission within user-specific minimum bandwidth.
摘要翻译：当分组到达整形单元500时，丢弃控制单元510判断是否“存储”或“丢弃”到达的分组。被判断为“存储”的包被存储在分组存储FIFO缓冲器520中，并且在大于每个用户最小带宽的总和的传输带宽内发送。带宽检查单元600检查每个用户的带宽，并将落入带宽内的分组判断为高优先级分组，并将落在带宽以外的分组作为低优先级分组。如果大量的分组被存储到分组存储FIFO缓冲器520中，则丢弃控制单元510确定低优先级分组被专门“丢弃”，从而确保高优先级分组被丢弃。因此，整形单元500确保在用户特定的最小带宽内的适当的分组传输。
