Patent ID: 7158522

Claim:
A method for optimizing session establishment between a source and a destination comprising: receiving a synchronization packet from the source at a first intermediate device; in response to the received synchronization packet, generating at the first intermediate device a synthesized synchronization-acknowledgment packet including information of the destination; sending the synthesized synchronization-acknowledgment packet from the first intermediate device to the source; outputting a characterized synchronization packet from the first intermediate device to the destination prior to receiving an acknowledgement packet from the source at the first intermediate device, wherein the characterized synchronization packet includes an initial sequence number synthesized by the first intermediate device for communication to a second intermediate device; receiving the characterized synchronization packet at the second intermediate device; removing the synthesized initial sequence from the characterized synchronization packet at the second intermediate device to form a characterization-free synchronization packet; and sending the characterization-free synchronization packet from the second intermediate device to the destination.
