Classification: CPC H | IPC H

Claim 10:
11. A server, comprising:
first and second network interface cards (NIC), each NIC having a label channel part configured for communication with a switch controller via a label channel, wherein the label channel is configured to deliver destination information of data packets carried by paired label packets to the switch controller from the NIC; and
for each NIC, a data channel part configured for communication with an optical switch via a data channel, wherein the data channel is configured to simultaneously transmit data packets aggregated by the NIC to the optical switch from the NIC;
wherein the switch controller is configured to generate switch-enabling signals to configure the optical switch based on received label destination information; and
wherein the optical switch is configured to send the data packets to a destination port; and
wherein the server is configured to utilize the label channels to distribute a clock frequency and synchronization time from a master clock of the switch controller to the first and second NICs, measure a physical fiber transmission delay of the label channels, and compensate the received synchronization time with the measured physical fiber transmission delay.
