1. A method for expediting data flow from a first point to a second point via a connection defined by a first set-up from the first point to an intermediate station, and a second set-up from the intermediate station to the second point, each set-up being established upon receipt of a connection acknowledgment corresponding to a connection request, the method comprising:

  • receiving a first connection request at the intermediate station, the first connection request having been transmitted from the first point;

    transmitting, from the intermediate station toward the second point, a second connection request;

    transmitting a first connection acknowledgment from the intermediate station toward the first point in response to the first connection request, to establish the first set-up, the first connection acknowledgment being transmitted prior to receiving a second connection acknowledgment corresponding to the second connection request;

    receiving data at the intermediate station, via the first set-up, prior to establishing the second set-up;

    storing the received data at the intermediate station; and

    forwarding the stored data from the intermediate station toward the second point after establishing the second set-up.
