Title:
DISTRIBUTION SYSTEM, NODE DEVICE, DATA PACKET RETRANSMITTING METHOD, AND SO FORTH
Document Type and Number:
WIPO Patent Application WO/2006/120836
Kind Code:
A1
Abstract:
A distribution system for efficiently retransmitting a missing data packet without burdening a specific device such as a distribution server with a heavy load, a node device, and a data packet retransmitting method are disclosed. In a distributing system where node devices form layers and are interconnected through communication channels and consecutive data packets are distributed through the node devices in a direction from the upstream side to the downstream side, each node device comprises packet receiving means for receiving the distributed consecutive data packets, missing packet detecting means for detecting a missing data packet, if any, in the received data packets, retransmission request sending means for sending information on missing data packet retransmission request to the other node devices than the node devices located on the downstream side, and retransmitted packet receiving means for receiving data packet retransmitted from the node device in response to the retransmission request information.
