Abstract:
1. A machine-implemented method of synchronizing a pseudo-time clock of a sender of a packet and a pseudo-time clock of a receiver of the packet, the method comprising: receiving, at the receiver, the packet sent from the sender; determining a first pseudo-time associated with the pseudo-time clock of the receiver; determining a second pseudo-time associated with the pseudo-time clock of the sender based on information in the packet; determining whether the pseudo-time clock of the receiver and the pseudo-time clock of the sender are unsynchronized by more than an allowed amount, based on comparing the first pseudo-time and the second pseudo-time; in response to determining that the pseudo-time clock of the sender is lagging the pseudo-time clock of the receiver by more than an allowed amount, sending, from the receiver to the sender, a packet comprising information from which a new pseudo-time can be determined that is based on the pseudo-time clock of the receiver, wherein the method is performed by the receiver, and wherein the receiver comprises a processor.
