20110292940 | SYSTEM AND METHOD FOR ESTABLISHING A COMMUNICATION PATH USING LABELS - A communication path is established by a sequence of nodes so that a data packet is transferred using labels each being assigned to a data link connecting each pair of adjacent nodes along the communication path. The sequence of nodes includes an origination node, one or more relay node, and a termination node, with being positioned in this order along the communication path. The origination node provides each of downstream nodes of the origination node with a path message for requesting establishment of the communication path. Each relay node, upon being provided with label assignment request information, performs label assignment processing for assigning a label to a data link connecting the relay node and an adjacent upstream node without depending on the label assignment processing performed on other nodes along the communication path so that the label assignment processing is concurrently performed on each of the downstream nodes. | 2011-12-01 |
20110292941 | TRANSMITTER AND CONTROL INFORMATION CONFIGURATION METHOD - A transmitter includes: a receiving unit to receive apparatus identification information that identifies transmitter and path identification information that identifies a data transfer path from another transmitter coupled to a local apparatus; a comparing unit to compare a value indicating an address assigned to the another transmitter to a value indicating an address assigned to the local apparatus; and a configuring unit to configure the local apparatus with apparatus identification information and path identification information determined by the local apparatus, or apparatus identification information and path identification information included in a frame received by the receiving unit, based on comparison results by the comparing unit. | 2011-12-01 |
