    摘要: In a system for transferring an analog video signal which contains command information and the like in vertical blanking interval VBI between master and slave devices via an analog line, information (bits 1 to 20) having a word configuration (words 0 to 2+CRCC) consisting of a predetermined number of bits (variable within the range from 5 bits to 80 bits) is superposed in a predetermined period (49.1 &mgr;s) of a predetermined VBI line (line number 10) at a predetermined clock (fsc/32 to fsc/2). In this manner, device which are interconnected via an analog video signal line can transfer information having various contents/lengths that can be changed in correspondence with a partner connected using vertical blanking interval VBI.

    摘要: A scheme for managing nodes connected to a home network according to their physical location is disclosed. A communication device constituting each node is formed by at least one communication unit for carrying out communications through a connected network, having communication ports for connecting nodes through which data are to be exchanged by the nodes, and a configuration information memory unit for storing a configuration information regarding a configuration of the communication device, having a region for dynamically describing a location information regarding a physical location of the communication device. At a managing node, a configuration information of a connected network and a location information regarding a physical location of a prescribed node connected to the network are collected, and physical locations of other nodes/services that are connected to the prescribed node are managed by regarding the other nodes/services as existing at an identical physical location as the physical location of the prescribed node as specified by the location information.

    摘要: A router device for controlling label switching path set up is disclosed. In the router device, a,policy information indicating a permitted starting point of a label switching path is stored, and a request message that contains a starting point information indicating a starting point node/network of the requested label switching path and a stream information indicating a desired packet stream to be transferred through the requested label switching path is received. Then, whether or not to permit the set up of the requested label switching path is judged by comparing the starting point information contained in the request message with the stored policy information, and the requested label switching path through the router device for the desired packet stream indicated by the stream information contained in the request message is set up when the set up of the requested label switching path is judged as permitted. Instead of the starting point information, a neighbor information, a stream information, or an ending point information may be used.
