Abstract:
1. A method of transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done via a multitransport tunnel from a first tunnel end-point to a second tunnel end-point, said multi-transport tunnel implementing a first carrier, and a second carrier wherein the first tunnel end-point performs steps, for a given frame of said multichannel data stream, of: receiving the multi-channel data stream input to the first tunnel end-point; obtaining, from the second tunnel end-point, at least one piece of information on quantity of data of said multi-channel data stream received by the second tunnel end-point; obtaining at least one piece of information on congestion of the first carrier; deciding, using the obtained at least one piece of information on the quantity of data and the obtained at least one piece of information on congestion, which channels of the given frame of said multi-channel data stream are to be routed to the first carrier of the multitransport tunnel and which channels of the given frame are to be routed to the second carrier of the multi-transport tunnel; routing the channels of the given frame of said multi-channel data stream decided by the deciding step to the first and second carriers of the multi-transport tunnel; supplying one piece of synchronization information with said plurality of channels; and transmitting to the second tunnel end-point each of the plurality of channels of said given frame via the decided carrier to which said channel has been routed, as well as its supplied piece of synchronization information, wherein said first carrier supports a transport protocol with acknowledgement and said second carrier supports a transport protocol without acknowledgement.
