Patent ID: 8582607

Claim:
A geographically diverse server system, comprising: a first server; a second server; an optical system interconnecting the first server and the second server over a transmit path and a receive path between the first server and the second server; wherein each of the first server and the second server is configured to: measure differential delay between the transmit path and the receive path; and compensate the differential delay between the transmit path and the receive path; wherein the optical system comprises a first network element connected to the first server and a second network element connected to the second server, and wherein the first network element is connected to the second network element through an optical network; a first external time reference connected to the first network element; and a second external time reference connected to the second network element; wherein the first network element is configured to calculate first transmit path delay and first receive path delay utilizing the first external time reference and wherein the second network element is configured to calculate second transmit path delay and second receive path delay utilizing the second external time reference.
