Patent ID: 8462821

Claim:
A method comprising: receiving, by a master node and from a slave node, a packet associated with a request to perform a modified two-step synchronization (sync) operation in a manner that precludes transmitting a follow-up packet, the modified two-step sync operation permitting the slave node to calibrate a clock, hosted by the slave node, to a master clock hosted by the master node; generating, by the master node and based on the request, a sync packet that includes information associated with a prior point in time when a prior sync packet was transmitted to the slave node; transmitting, by the master node, the sync packet to the slave node, the sync packet enabling the slave node to determine a quantity of delay associated with traffic that is being transported from the master node to the slave node based on the prior point in time and a time when the sync packet was received by the slave node; receiving, by the master node and from the slave node, a delay request packet; and transmitting, by the master node and to the slave node, a delay response packet as a response to the delay request packet, the delay response packet including information associated with another point in time when the delay request packet was received by the master node, and the delay response packet enabling the slave node to determine another quantity of delay associated with traffic that is being transported from the slave node to the master node based on the other point in time and a further time when the delay request packet was transmitted, to the master node, by the slave node.
