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 router in a backup path in an MPLS network adopting a label stack method aims to achieve the same quality-guarantee control as the one performed in a current path. In a packet transfer device accommodating first and second output lines, when the first line has a fault, upon a first packet being received, communication quality information in a header of the first packet is copied. A first header containing the copied priority information and a new label is added to the first packet, and the first packet is outputted to a second output line. When a second packet is received, communication quality information in a header of the second packet is copied, a second header containing the copied priority information and the new label is added to the second packet, and the second packet is outputted to the second output line.

摘要： A network switching device includes multiple ports, multiple switching processors, and a table manager. The switching processors respectively have an address table, a output port specification module, an update requirement determination module, and a table update module. The output port specification module refers to a destination address in received data and the address table and specifies a output port for sending the data among the multiple ports. The update requirement determination module determines requirement for update of the address table with regard to a source address in the data. The table manager has an update detail acquisition module and an update request module. Upon determination of the requirement for update of the address table, the update detail acquisition module obtains an update detail of the address table from one of the switching processors. The update request module sends an update request to the switching processors, based on the update detail.

摘要： In the case of a “distributed” integrated network node (architecture), a specific judgment process cannot be executed in any routing and transferring unit. The routing and transferring unit has been required to share such judgment process related information with an enhanced processing unit or with other routing and transferring units. Thus the manufacturing cost has increased when using an enhanced processing unit and the processing speed has been lowered unavoidably when cooperation is required among routing and transferring units. Those have been conventional problems. Furthermore, if any flow is disposed during a transfer from a packet transferring unit provided in a routing and transferring unit to a processing unit, the packet is disposed regardless of the packet priority. This has also been another conventional problem. According to the present invention, however, it is ruled that a packet related to a specific judgment process is always transmitted to a specific routing and transferring unit from a line interface unit. And if a flow is inputted and it is over the transferring capacity between a line interface unit and a routing and transferring unit, the line interface unit analyzes the packet header and determines the type, transport priority, and disposal priority of the packet.

摘要： A router comprising a priority level distinguishing means for distinguishing the priority level of a packet by referring to the information contained in the header of the packet, a routing table where an output path comprising one or more output lines can be mapped to each level of priority, an output path determining unit that searches the routing table and determines an output path to be used for sending out packets, and a preferential delivery controller that executes delivery control in accordance with the priority level for each output line corresponding to the output path. In response to a fault state in a preferred output line, the router can reroute high priority packets over an alternative output line while maintaining priority. The router may also calculate a distribution ratio to determine the optimal load for each output line for a given packet priority.

To comply with such a request, a discard information analyzer of apparatus administrator, for instance, analyzes the number of discard packets, the number of receiving packets or the number of transmitting packets counted by a bandwidth monitor of packet receiver or a bandwidth controller of packet transmitter and in accordance with the result of analysis, automatically sets, in an OUT side flow controller or In side flow controller, information for identifying a flow subject to flow control. Further, the OUT side flow controller or IN side flow controller picks flow statistic information from packets belonging to the object flow by using the set flow identification information.
