COMMUNICATION METHOD BETWEEN NODES OF PEER-TO-PEER NETWORK USING A COMMON GROUP LABEL, ESPECIALLY IN RELATION TO COMMUNICATING BETWEEN DIGITAL APPLIANCE DEVICES OR COMPUTERS

摘要

PURPOSE: A communication method between nodes of a peer-to-peer network using a common group label is provided to assign a common group label to a node which is a member of node groups, so that the node can cooperate with all other members within the same node groups, thereby reducing an amount of technical management by using the common group label. CONSTITUTION: A node group(OZ_42) is accessed by nodes(N42,N44) which are not members of node groups(P2P_1,P2P_2). A group label(Z_ID0) of the nodes(N42,N44) accessing the node group(OZ_42) is detected. A device checks whether the nodes having the detected group label(Z_ID0) are permitted to access the accessed node group(OZ_42). The device supplies services or resources to the accessing nodes(N42,N44) by the node group(OZ_42).
