摘要： An edge router measures a traffic volume inputted into a network, and the measurement result is notified to a network management server. If the network management server judges that the notified traffic volume is “smaller” than a capacity of a second core router, it will direct a first core router to shift to a power saving mode. The first core router notifies the edge router of the shift to the power saving mode, and the edge router updates a routing table so that the packet to the first core router may be bypassed to the second core router. The first core router shifts to the power saving mode that does not perform packet transfer, and reduction in electric power is realized.

摘要： A master node transmits a probe packet for checking a condition of a network in a ring in both directions thereof to detect the occurrence of a fault on the ring. A slave node increments a hop count included in the received probe packet, transmits it to an adjacent node configuring the ring, and transmits a hop count report packet to the master node. The master node detects a fault on the ring based upon a fact that the master node does not receive the probe packet transmitted by itself. Further, the master node detects the occurrence of multiple faults and the recovery of at least one of the multiple faults based upon the sum of maximum values of hop counts in the hop count report packets received from both directions of the ring and transmits a packet for prompting the update of the database for packet transfer.

摘要： A high quality network is provided that eliminates the sorting time for sorting through registering look-up conditions, such as source and destination MAC addresses, in a content addressable memory, by generating a routing or flow control look-up key, and then selectively activating some of the physical banks in the content addressable memory with the look-up key during look-up for the look-up conditions. The look-up key is generated by extracting a part or all of the data contained in a packet header.

摘要： A high quality network is provided by not generating a sorting time when registering look-up conditions in a content addressable memory, and the physical banks activated during look-up of the look-up conditions are limited. The power consumption in a content addressable memory for routing and content addressable memory for flow control can be reduced by a hash function unit for routing for limiting the physical banks to be made active in a content addressable memory for routing which uses a routing look-up key or routing look-up data as input elements, and a routing register which stores values showing one or more physical bank numbers for converting hash values which may have discrepancies, and a hash function unit for flow control for limiting the physical banks to be made active in a content addressable memory for flow control which uses a flow control look-up key or flow control look-up data as input elements, and a flow control register which stores values showing one or more physical bank numbers for converting hash values which may have discrepancies.
