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： 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 traffic statistical analysis processing unit is provided in a network control apparatus so as to detect an abnormal traffic. When the abnormal traffic is detected, a filter is set to a packet transfer processing unit so as to stop transferring operation of the abnormal traffic. At the same time, abnormal condition sensing information is superimposed on a statistical information packet, and the resulting statistical information packet is transmitted to a traffic analyzing apparatus.

摘要： A cache memory contained in a processor features a high efficiency in spite of its small capacity.In the cache memory control circuit, it is detected whether the access operation of the processor is directed to a particular region of the memory, and when the data is to be read out from, or is to be written onto, the particular region, the data is copied onto the cache memory and when the data is to be read out from other regions, operation of the memory is executed immediately without waiting for the reference of cache memory.By assigning the particular region for the data that is to be used repeatedly, it is possible to provide a cache memory having good efficiency in spite of its small capacity. A representative example of such data is the data in a stack.

摘要： A packet information extraction circuit derives predetermined key information (for example, destination information or transmission source information) from a received packet. A HASH result computation circuit generates m (a plurality of) pseudo-random numbers (HASH results) of fixed length from the derived information. A cache table holds the key information and cumulative packet lengths within a predetermined time period by using the generated pseudo-random numbers as addresses. When a threshold value holding and comparing circuit senses that the cumulative packet length has exceeded a value held therein, it sends a notification signal to judgment means disposed in a packet exchange system. The key information items and the cumulative values of the packet lengths are stored in the cache table on the basis of the received packets in such a way that larger cumulative packet lengths are left behind, whereas smaller cumulative packet lengths are erased.
