摘要： A network relay apparatus which conducts data transfer by using a plurality of network LSIS includes a transfer engine unit having at least two network LSIs and a central control unit which controls the operation state of the network relay apparatus. The transfer engine unit includes the network LSIs capable of changing over at least one of a clock and an operation which differ every function block, a load judgment unit for judging a load laid upon each of function blocks in the network LSI, and a frequency voltage control unit for individually changing over at least one of the clock and operation voltage supplied to each function block on the basis of the load judged by the load judgment unit.

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.
摘要翻译：主节点在其两个方向上发送用于检查环中的网络的状况的探测分组，以检测环上的故障的发生。从节点增加收到的探测报文中包含的跳数，将其发送给配置环的相邻节点，并向主节点发送跳数报告报文。主节点基于主节点未接收到自身发送的探测分组的事实，检测到环上的故障。此外，主节点基于从环的两个方向接收到的跳数计数报告分组中的跳数的最大值的总和，检测多个故障的发生和多个故障中的至少一个的恢复，并且发送用于提示更新数据包以进行数据包传输。
