Devices and methods for synchronizing devices over a switched fabric. A switch receives a request packet from a device, transmits a completion packet to the device, determines an in-switch delay, and stores the in-switch delay. Another switch receives a packet from a first device, forwards the packet to a second device, determines an in-switch delay of the packet, and stores the in-switch delay. Storing of in-switch delays may include adding an in-switch delay to values in one or more transaction delay fields of a packet. Storing of in-switch delays may include storing the delays in a storage element of a switch. In-switch delay may be determined as a difference between a receiving time corresponding to reception of a packet and a forwarding or transmittal time corresponding to forwarding or transmitting of a packet. |
