Methods, systems, and computer readable media for determining one-way flow latency of multi-path switching environment

A system for determining one-way packet flow latency of a multi-path switching environment, the system comprising:

• a test device including at least one processor and a memory;
• a source host emulated by the test device for transmitting a plurality of test packets associated with a first packet flow from a network test device through a multi-path switching environment to a destination;
• a destination host emulated by the test device for receiving the plurality of test packets associated with the first packet flow;
• and
• a test controller associated with the test device for determining a time required to transmit the first packet flow into the multi-path switching environment, determining a time required to receive the first packet flow from the multi-path switching environment, and determining a one-way flow latency for the first packet flow as a difference between the time required to receive the first packet flow from the multi-path switching environment and the time required to transmit first packet flow into the multi-path switching environment.

A non-transitory computer readable medium having stored thereon executable instructions that when executed by a processor of a computer control the computer to perform steps comprising:

• transmitting a plurality of test packets associated with a first packet flow from a network test device through a multi-path switching environment to a destination;
• determining, by the test device, a time required to transmit the first packet flow into the multi-path switching environment;
• receiving, by the test device or by a separate test device functioning as the destination, the plurality of test packets associated with the first packet flow;
• determining, by the test device or the separate test device, a time required to receive the first packet flow from the multi-path switching environment;
• and
• determining a one-way flow latency for the first packet flow as a difference between the time required to receive the first packet flow from the multi-path switching environment and the time required to transmit first packet flow into the multi-path switching environment.
