Abstract:
Methods and apparatus are disclosed for transmitting flows of data units across a data communication network from a transmitting node towards an intended destination via one or more intermediate nodes, the data units having destination indications, the intermediate nodes being configured to receive data units, identify therefrom a transmission mode that has been selected from at least two transmission modes for the data units, and forward the data units according to the selected transmission mode. The method involves selecting a transmission mode for the flow in dependence on an estimate of the difference in the amount of a resource required to transmit the flow by one or the other transmission mode, a resource-usage measure indicative of the amount of the resource required to identify a route and reserve sufficient capacity thereon for transmission of the flow, and a probability measure indicative of a likelihood of success of an attempt to identify and reserve sufficient capacity for the flow.

Claim (Index 1):
A method of transmitting a flow comprising a plurality of data units across a data communication network from a transmitting node towards an intended destination via one or more of a plurality of intermediate nodes, data units of the flow having respective indications of an intended destination for data units of the flow, the intermediate nodes of the network being configured to receive data units, to identify from a characteristic of received data units a transmission mode that has been selected from at least two transmission modes for the data units, and to forward said data units according to the selected transmission mode, the transmission modes comprising:\n a first transmission mode according to which a predetermined header portion of a received data unit is inspected following receipt by an intermediate node in order to obtain the indication of the intended destination for the received data unit, and whereby the received data unit is then forwarded by said intermediate node to a subsequent node selected by the intermediate node in dependence on the obtained indication of the intended destination; and a second transmission mode according to which a characteristic of a received data unit signals to intermediate nodes that the data unit is to be forwarded to a subsequent node on an already-identified route identified in dependence on the intended destination for data units of the flow, and whereby the received data unit is forwarded by each intermediate node to a subsequent node on the identified route; the method comprising: in respect of one or more data units of a flow to be transmitted from the transmitting node, obtaining a measure of the estimated difference between the amount of a predetermined resource required to transmit the data units of the flow from the transmitting node to the intended destination according to the first transmission mode and the amount of the predetermined resource required to transmit the data units of the flow from the transmitting node to the intended destination according to the second transmission mode; at a processor associated with the transmitting node, selecting a transmission mode for the data units of the flow, the selection being made in dependence on the obtained measure of the estimated difference, a resource-usage measure indicative of an estimated amount of the predetermined resource required to be used in an attempt to identify a route from the transmitting node to the intended destination and reserve sufficient capacity on said route for transmission of said flow according to said second transmission mode, and a probability measure indicative of a likelihood of success of an attempt to identify and reserve sufficient capacity on a route from the transmitting node to the intended destination; and in the event that the first transmission mode is selected, forwarding data units of the flow received by the transmitting node to one or more intermediate nodes with the indication of the intended destination in the predetermined header portion of said data units, for subsequent forwarding according to the first transmission mode; and in the event that the second transmission mode is selected, initiating a route-identification process to identify and reserve sufficient capacity on a route from the transmitting node towards the intended destination for transmission of the data units of the flow according to the second transmission mode.
