Abstract
A plurality of bridges accommodating LANs are connected through an ATM network in a network system of the present invention. When a specified bridge is newly connected to this ATM network, the specified bridge transmits a request for setting point-to-multipoint transmission SVCs towards other bridges. These other bridges, when receiving the setting request from the specified bridge, execute a process of setting the point-to-multipoint transmission SVCs with respect to the specified bridge.
Claims24
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein a specified bridge among said plurality of bridges sends a request for setting a switched virtual connection for a point-to-multipoint transmission, towards any one of bridge among other bridges, and
- each of said other bridges, when receiving the setting request sent from said specified bridge, sets the switched virtual connection for point-to-multipoint transmission between said specified bridge and said other bridge.
2 more elements
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein each of said bridges is connected to each of other bridges through a connection for point-to-point transmission, and
- wherein each of said bridges, if there is an unused connection among the connections accommodated in said bridge, gives said ATM network a rate decreasing message for decreasing a transmission rate of the unused connection, and
- said ATM network, when receiving the rate decreasing message, decreases the transmission rate of the unused connection by releasing resources allocated to the unused connection, and allocates the released resources to a other connection.
3 more elements
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein a specified bridge among said plurality of bridges is connected to other bridges through connections for a point-to-multipoint transmission, and
- wherein said specified bridge, when transmitting a packet to each of said other bridges by use of said connections, and if there is a other bridge not requiring the packet, gives said ATM network a rate decreasing message for decreasing a transmission rate of a target connection which is used only for transmitting a packet to said other bridge among said connections, and
- said ATM network releases resources allocate to the target connection corresponding to the rate decreasing message, thus decreases the transmission rate of the connection, and allocates the released resources to a other connection.
3 more elements
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein each of said bridges is connected to other bridges through connections, and
- wherein each of said bridges, if a packet received from a other bridge is unnecessary, gives said ATM network a rate decreasing message for decreasing a transmission rate of a target connection connected said other bridge and said bridge, and
- said ATM network releases resources allocated to the target connection corresponding to the rate decreasing message, thus decreases the transmission rate of the target connection, and allocates the released resources to a other connection.
3 more elements
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein a specified bridge among said plurality of bridges is connected to said other bridges through connections, and
- wherein said specified bridge transmits a first packet to said other bridges by use of said connections, monitors a response condition of each of said other bridge s with respect to the first packet, and transmits a second packet to only connections corresponding to said other bridges having responded said first packet.
2 more elements
A network system comprising:
- a ATM network;
- and
- a plurality of bridges connected through said ATM network,
- wherein a specified bridge among said plurality of bridges is connected to other bridges through a plurality of connections for point-to-multipoint transmission, and
- said specified bridge transmits a first packet to said other bridges by use of the connections, monitors a response condition of each of said other bridges with respect to the first packet, and transmits a second packet to only connections to which said other bridges having responded to the first packet belong.
2 more elements
A bridge connected through an ATM network to a plurality of other bridges,
- wherein said bridge, when physically connected to said ATM network, transmits to each of said other bridges a request for setting a switched virtual connection for point-to-multipoint transmission between each of said other bridges and said bridge.
A bridge connected through an ATM network to a plurality of other bridges,
- wherein said bridge is connected to each of said other bridge equipments through a point-to-point transmission connection, and
- wherein said bridge, if there is an unused connection among the connections, gives said ATM network a rate decreasing message, and thus makes said ATM network decrease a transmission rate of the unused connection corresponding to the rate decreasing message.
A bridge connected through an ATM network to a plurality of other bridges,
- wherein said bridge is connected to said other bridges through connections for point-to-multipoint transmission, and
- wherein said bridge, when transmitting a packet to said other bridges by use of the connections, and if there are a other bridge not requiring the packet, gives said ATM network a rate decreasing message for decreasing transmission rates of a target connection which are used only for transmitting a packet to said other bridge among the connections, and thus makes said ATM network decrease the transmission rate of the target connection corresponding to the rate decreasing message.
A bridge connected through an ATM network to a plurality of other bridge,
- wherein said bridge is connected through connections to said other bridge, and
