摘要： A data relay device includes a plurality of transmission ports that constitutes a logical port, and stores therein a MAC learning table and a CoS distribution table. The data relay device reads a MAC address and a CoS value from a frame, and reads a logical-port ID corresponding to the MAC address from the MAC learning table. The data relay device reads a transmission-port ID corresponding to the logical-port ID and the CoS value from the CoS distribution table, and outputs the frame to a transmission port indicated by the transmission-port ID. On the transmission port, the frame is stored in a transmission queue corresponding to the CoS value, and the frame is transmitted at a shaping rate assigned to the transmission queue.

摘要： In a data transmission method and apparatus which can perform a switchover of all of the main lines without requiring much construction cost, a transmission apparatus sets, upon frame transmission or reception, combinations of a plurality of main lines with virtual paths established so as to include at least a part of a bandwidth of the main lines in one or more protection lines as redundant configurations. Upon frame transmission, the apparatus copies frames received in the main lines, assigns identifiers of the redundant configurations to the copied frames, and transmits the copied frames to the virtual paths of the redundant configurations. Upon frame reception, the apparatus determines whether the main lines or the virtual paths forming the redundant configurations are valid, deletes the identifiers of the redundant configurations assigned to frames received from the protection lines, and determines whether the frames from which the identifiers have been deleted should be respectively discarded or transferred depending on validity or invalidity of the main lines.

摘要： A transfer system for bundle transfer, in which the amount of route information and the number of times advertisement is performed are reduced, and maintenance and management are made to be highly efficient to implement improved transfer quality. A path setting section specifies a path between nodes for a receiving side as a bundled link which can have a plurality of paths tied up. A transmission-side route-information advertisement section advertises route information in a network when recognizing that the path has been established. A path recognition section recognizes the path and sets the path as a bundled link. A receiving-side route-information advertisement section advertises the route information in the network when recognizing that the path has been established.

摘要： A resilient packet network (RPR) device is connected to one or more rings to constitute an RPR network. The RPR device has a storage unit in which a correspondence between RPR device addresses, each indicating an RPR device connected to the one or more rings, and user device addresses, each indicating a user device accommodated in the RPR device, is stored. When the RPR device receives data addressed to a predetermined user device from a user device accommodated in the RPR device itself, if an RPR device address of an RPR device accommodating the predetermined user device is registered in the storage unit, an RPR header, in which the RPR device address is set as a destination RPR device address, is added to the data. The data with the RPR header is transmitted to the RPR network.

摘要： In a network providing a wide-area LAN service which allows communications to be performed between user networks (12, 13) via a carrier network (11), edge switches (14, 15) each comprise: a tentative learning registration means (16) which, when a packet whose source MAC address and receiving port are not yet learned is received from the carrier network, registers the source MAC address and the receiving port in a tentatively learned state; a learned state changing means (17) which changes the learned state of the destination MAC address of a packet received from an associated one of the user networks to a permanently learned state; and a permanent learning registration means which, when a packet whose destination MAC address is registered in a learned state is received from the carrier network, registers the source MAC address and receiving port of the packet received from the carrier network in a permanently learned state. The invention thus provides a MAC address learning apparatus that improves the hit rate in a MAC address learning table maintained in each of the edge switches (14, 15) provided in a wide-area VLAN carrier network.

摘要： When setting up a working path, a protection path is automatically set up by taking each node on the working path as a start point. A working path setup request message carrying “protection needed/not-needed” information is transmitted from an ingress node toward an egress node along the route of the working path. When transferring a path setup response message as a response to it, each node autonomously determines the route of the protection path and sends out a protection path setup request message along the route of the protection path.
