Deterministic calibrated synchronized network interlink access

A system comprising:

• one or more processors;
• and
• one or more computer-readable storage devices having stored therein instructions which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• determining whether respective clock rates associated with the first switch, the second switch, and the third switch have a clock rate variation, to yield a clock rate variation determination;
• based on a) a first communication latency of a first link between a first processing element associated with a first switch and a second processing element associated with a second switch and b) a second communication latency associated with a second link between the first processing element and a third processing element in a third switch, determining a delta between the first communication latency and the second communication latency;
• based on the delta and the clock rate variation determination, determining an offset value for synchronizing the first communication latency and the second communication latency;
• and
• based on the offset value, instructing a calibration element to calibrate traffic over at least one of the first link and the second link by delaying at least a portion of the traffic.

A non-transitory computer-readable storage medium having stored therein instructions which, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• calculating a first communication latency of a first link between a first processing element associated with a first switch and a second processing element associated with a second switch;
• calculating a second communication latency associated with a second link between the first processing element and a third processing element in a third switch;
• determining whether respective clock rates associated with the first switch, the second switch, and the third switch have a clock rate variation, to yield a clock rate variation determination;
• determining a delta between the first communication latency and the second communication latency;
• based on the delta and the clock rate variation determination, determining an offset value for synchronizing the first communication latency and the second communication latency;
• and
• based on the offset value, calibrating traffic over at least one of the first link and the second link by delaying at least a portion of the traffic.
