Abstract
A transmitting apparatus transmits a data stream via multiple wireless links and includes a storage unit that stores a guaranteed rate to be guaranteed for the data stream; a dividing unit that divides traffic of the data stream into first traffic corresponding to the guaranteed rate stored in the storage unit and second traffic corresponding to a portion of the traffic exceeding the guaranteed rate; and a distributing unit that distributes the first traffic to at least any one of the wireless links preferentially over the second traffic, and distributes the second traffic to available bandwidths of the plural wireless links.
Claims11
A transmitting apparatus that transmits a data stream via a plurality of wireless links, the transmitting apparatus comprising:
- a storage unit that stores a guaranteed rate to be guaranteed for the data stream;
- a dividing unit that divides traffic of the data stream into first traffic corresponding to the guaranteed rate stored in the storage unit and second traffic corresponding to a portion of the traffic exceeding the guaranteed rate;
- a distributing unit that distributes the first traffic to at least any one of the wireless links preferentially over the second traffic, and distributes the second traffic to available bandwidths of the plurality of wireless links according to a ratio of available bandwidths of the plurality of wireless links after the first traffic has been distributed;
- and
- a correspondence information storage unit that stores correspondence information that correlates the data stream and a wireless link whose lowest transmission rate is greater than or equal the guaranteed rate of the plurality of wireless links;
- wherein
- the distributing unit distributes the first traffic to the wireless link that is correlated with the data stream in the correspondence information stored in the correspondence information storage unit.
A transmitting apparatus that transmits a plurality of data streams via a plurality of wireless links, the transmitting apparatus comprising:
- a storage unit that stores a guaranteed rate to be guaranteed for each of the data streams;
- a dividing unit that divides traffic of each of the data streams into first traffic corresponding to the guaranteed rate stored in the storage unit and second traffic corresponding to a portion of the traffic exceeding the guaranteed rate;
- a distributing unit that distributes the first traffic of each of the data streams to at least any one of the wireless links preferentially over the second traffic of each of the data streams, and distributes the second traffic of each of the data streams to available bandwidth of each of the plurality of wireless links according to a ratio of available bandwidths of the plurality of wireless links after the first traffic has been distributed;
- and
- a correspondence information storage unit that stores correspondence information that correlates the data stream and a wireless link whose lowest transmission rate is greater than or equal the guaranteed rate of the plurality of wireless links;
- wherein
- the distributing unit distributes the first traffic to the wireless link that is correlated with the data stream in the correspondence information stored in the correspondence information storage unit.
A transmission method executed by a transmitting apparatus that transmits a data stream via a plurality of wireless links, the transmission method comprising:
- acquiring a guaranteed rate to be guaranteed for the data stream;
- dividing traffic of the data stream into first traffic corresponding to the acquired guaranteed rate and second traffic corresponding to a portion of the traffic exceeding the guaranteed rate;
- distributing the divided first traffic to at least any one of the wireless links preferentially over the second traffic, and distributing the second traffic to available bandwidth of the plurality of wireless links according to a ratio of available bandwidths of the plurality of wireless links after the first traffic has been distributed;
- acquiring correspondence information that correlates the data stream and a wireless link whose lowest transmission rate is greater than or equal the guaranteed rate of the plurality of wireless links;
- and
- distributing the first traffic to the wireless link that is correlated with the data stream in the acquired correspondence information.
A transmission system that transmits a data stream via a plurality of wireless links, the transmission system comprising:
- a first transmitting apparatus that acquires a guaranteed rate to be guaranteed for the data stream, divides traffic of the data stream into first traffic corresponding to the acquired guaranteed rate and second traffic corresponding to a portion of the traffic exceeding the guaranteed rate, distributes the first traffic to at least any one of the wireless links preferentially over the second traffic, distributes the second traffic to available bandwidth of the plurality of wireless links according to a ratio of available bandwidths of the plurality of wireless links after the first traffic has been distributed, acquires correspondence information that correlates the data stream and a wireless link whose lowest transmission rate is greater than or equal the guaranteed rate of the plurality wireless links, and distributes the first traffic to the wireless link that is correlated with the data stream in the acquired correspondence information;
- and
- a second transmitting apparatus that receives the data stream distributed to the plurality of wireless links and transmitted by the first transmitting apparatus.
