摘要： A multiplex router device, having a multiplex configuration, is instrumental in reducing internal and external traffic flows for a routing protocol process that occurs at a time of system switchover. A data base integration module, in a route calculation unit in the active mode, stores network link-state information collected by a routing protocol packet transmission-reception module in a link-state data base, and at the same time sends the information to a route calculation unit, but does not send routing protocol information collected. In the route calculation unit in the standby mode, a data base integration module that received the network link-state information stores its contents into its own link-state data base. When a failure occurs in the route calculation unit in the active mode, the route calculation unit performs the routing protocol process by using the stored link-state data base.

摘要： A multicast communication device receives data packets multicast for receiving terminals which terminals do not support multicast communication and that are requesting multicast data packets. The multicast communication device then forwards the data packets to the receiving terminals. Communication from the receiving terminal accessing the sending terminal sending data packets to obtain information is monitored. Based on the access contents, a join group request is issued for the group address used by the multicast delivery. The multicast communication device stores service information such as the address of the sending terminal and the destination address of data packets sent by the sending terminal. If the service to be accessed by the receiving terminal is present, multicast delivery of data packets is requested. The multicast communication device forwards received multicast data packets to the receiving terminal.

摘要： For continuing multicast data transfer according to path control information after being switched from an active status to a standby status, it is necessary that the standby status hold the same path control information as the active status. However, a synchronization of the path control information thereof is not guaranteed. To solve the above-mentioned problem, this invention provides a data transfer apparatus coupled to a network, including a plurality of interfaces for transmitting and receiving data, in which the data transfer apparatus is configured to: create transfer destination information for correlating a destination of the data with the interfaces for transmitting the data to be transmitted to the destination; and transmit, upon reception of multicast data via one of the interfaces before being judged that the transfer destination information has been created, the multicast data from at least one of the interfaces irrespective of the transfer destination information.

摘要： In a network relay router 10, a multicast routing protocol processing module 11A sequentially sends a join request message (CP1) to a router 30a functioning as a rendezvous point via an interface 101, based on the settings of a multicast group address or destination address and a sender VRF name. The network relay router 10 receives a multicast packet (DP1) from the router 30a via the interface 101 and acquires a sender address or source address of a transmission device SE from the received multicast packet. The network relay router 10 sends a join request message (CP2) via an interface 102 on the side of the transmission device SE and receives a multicast packet via the interface 102. This establishes an optimum multicast route (MR) between the transmission device SE and the network relay router 10.
