摘要： PROBLEM TO BE SOLVED: To automatically realize the optimal setting or release of an optical path according to AC traffic quantity between electric sub-networks. SOLUTION: The measured AC traffic quantity of each LSP is reported to an electric boarder node or an optical boarder node. The optical board node receives it and reports it to another optical boarder node. The optical boarder node exchanges the AC traffic quantity with each other to acquire AC traffic information between respective electric sub-networks. Then, the optical board node realizes the autonomous distributed setting or release of the optical path based on the information. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To allow even a general user to quickly download large amounts of information without increasing the processing load of a network. SOLUTION: When a user side edge node detects a data request signal for an information providing server from a user, a cut through-path directly communicated from the information providing server to a route for a user is formed between an edge router connecting the user and an edge router connecting the information providing server. When the server side edge node detects that traffic amounts from the information providing server to the user exceed a predetermined threshold, the cut through-path directly communicated from the information providing server to the router for the user is formed between the edge router connecting the user and the edge router connecting the information providing server.

摘要： PROBLEM TO BE SOLVED: To flexibly cope with increase/decrease in a scale of switch by transmitting a congestion surveying cell from an incoming side channel unit to an outgoing side channel unit and returning the congestion surveying cell from the outgoing side channel unit to the incoming side channel unit that is a sender of the cell. SOLUTION: The ATM switch is provided with a channel unit 2 that accommodates an incoming channel 1, a channel unit 4 that accommodates an outgoing channel 5, and a unit switch 3 to set a transfer path of a cell. The channel unit 2 transmits an OAM cell being a congestion surveying cell to the channel unit 4, and the channel unit 4 returns the cell to the channel unit 2 that is a sender of the cell. The unit switch 3 discriminates the occurrence of congestion according to the number of cells stored in a buffer 50 and writes discriminated congestion indicating information to the OAM cell. Congestion of the transfer path of the OAM cell is detected by reading the congestion indicating information.

摘要： PROBLEM TO BE SOLVED: To easily generate a packet which is used for the push-type service by giving a contents identifier or a category identifier, which identifies the contents identifier and the category to which the contents belong as to the packet. SOLUTION: A contents ID giving part 3 gives a contents identifier to a packet to identify the contents of information stored in the packet. A distribution network 10 has a contents filter 1, which decides whether the packet to which the information contents are given should be distributed to a prescribed user terminal 8 in accordance with the contents identifier. The filter 1 includes a COI table, where the information on the contents identifier are registered in response to the destinations and passes a packet, when the contents identifier given to the packet matches with the contents identifier registered on the COI table via a pass/disuse controller. The COI table registers the information on the contents identifier according to the declaration of a user.
