Patent ID: 8072898

Claim:
A method for managing a transmission of data streams on a transport channel of a tunnel, the transmission of each stream being performed on said transport channel according to a transport protocol scheduled by packets and with acknowledgment, the tunnel being implemented between a first and a second tunnel end-point connected respectively to a first and a second sub-network, each stream being transmitted from a sender device to a receiver device, one device among said sender device and said receiver device being connected to the first sub-network and the other to the second sub-network, said method being performed by said first tunnel end-point and comprising the following steps: detecting a loss of packet on the transport channel of the tunnel; identifying at least one stream having at least one packet blocked on the transport channel of the tunnel by said loss; and for at least one identified stream, generating and transmitting at least one acknowledgment to the sender device that has transmitted, on the tunnel, a packet blocked by said loss, said sender device re-initializing its retransmission timeout (RTO) upon reception of said at least one acknowledgement.
