Method for transmitting a multi-channel data stream on a multi-transport tunnel, corresponding computer-readable storage means and tunnel end-points

摘要

A method is disclosed for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being done via a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, the multi-transport tunnel implementing at least one first carrier supporting a transport protocol with acknowledgement and at least one second carrier supporting a transport protocol without acknowledgement.;More specifically, the invention proposes to introduce a delay in the sending of data (<>) via the first carrier as compared with the sending of data (<>) via the second carrier. Thus the invention guarantees the order of arrival of channels that are associated with a same piece of synchronization but are transmitted on distinct first and second carriers and come from the separation of a same multi-channel data frame.

1. A method for transmitting a multi-channel data stream comprising frames comprising a plurality of channels, the transmitting being performed via a multi-transport tunnel from a first tunnel end-point to a second tunnel end-point, said tunnel implementing at least one first carrier supporting a transport protocol with acknowledgement and at least one second carrier supporting a transport protocol without acknowledgement,
wherein the first tunnel end-point performs the steps of: determining, for each channel of a given frame of the multi-channel data stream received by the first tunnel end-point, based on a predetermined routing criterion, whether the channel is to be routed to the first carrier or to the second carrier of the multi-transport tunnel; routing channels of the frame of said multi-channel data stream determined in the determining step to be routed to the first carrier to said first carrier of the multi-transport tunnel and routing channels of the frame of said multi-channel data stream determined in the determining step to be routed to the second carrier to the second carrier of the multi-transport tunnel; supplying one piece of synchronization information with said channels; obtaining a first piece of feedback information relative to a transmission timing relationship between said first and second carriers; and applying a delay before transmitting said channels routed to the first carrier, said delay being determined as a function of said first piece of feedback information.
