USING NETWORK INTERFACE CARDS HAVING PROCESSING UNITS TO DETERMINE LATENCY
Abstract:
A system is configured to compute a latency between a first computing device and a second computing device. The system includes a network interface card (NIC) of a first computing device. The NIC includes a set of interfaces configured to receive one or more packets and send one or more packets. The processing unit is configured to identify information indicative of a forward packet, compute, based on a first time corresponding to the forward packet and a second time corresponding to a reverse packet associated with the forward packet, a latency between the first computing device and a second computing device, wherein the second computing device includes a destination of the forward packet and a source of the reverse packet, and output information indicative of the latency between the first computing device and the second computing device.
