Claim:
1. A computer-implemented method comprising: sending a synchronization packet to a server in a network, wherein the synchronization packet identifies a primary source port and a set of backup source ports different from the primary source port; receiving an acknowledgement message from the server responsive to the synchronization packet; determining, from the acknowledgement message, whether the server supports receiving packets sent from the backup source ports as though they were sent from the primary source port; sending at least one of a plurality of data packets from the primary source port; and when the acknowledgement message indicates that use of the backup source ports is supported, sending one or more of the plurality of data packets using one or more backup source ports in the set of backup source ports; and further comprising: generating a mapping from the set of backup source ports to the primary source port if the acknowledgement message indicates that the server supports receiving the packets sent from the backup source ports as though they were sent from the primary source port.
