Abstract
A method and apparatus for synchronizing time between a master device and a target device arranged across a network, wherein the target device communicates to the master device through a PCIe interconnect includes transmitting a first message at a first time from the master device to the target device, the first message including a message indicator; and receiving a reply message at a subsequent time from the target device to the master device, the reply message including the message indicator.
Claims30
A method comprising:
- transmitting a first message at a first time from a master device to a target device to synchronize time between the master device and the target device arranged across a network, wherein the target device communicates to the master device through a PCIe interconnect, the first message including a message indicator indicating that the first message originated at the master device;
- and receiving a reply message at a subsequent time from the target device to the master device, the reply message including the message indicator indicating that the reply message originated at the target device.
A system comprising a master device and a target device, wherein the master device is configured to transmit a first message at a first time from the master device to the target device to synchronize time between the master device and the target device arranged across a network, wherein the target device is configured to communicate to the master device through a PCIe interconnect, the first message including a message indicator indicating that the first message originated at the master device;
- and wherein the master device is configured to receive a reply message at a subsequent time from the target device to the master device, the reply message including the message indicator indicating that the reply message originated at the target device.
