Automatic discovery maximum transmission unit adjustment

A non-transitory, machine-readable medium storing instructions, which when executed by one or more processing resources, cause the one or more processing resources to:

• send, by a first computing system, a first plurality of test packets over at least one path in a network to a second computing system;
• receive, by the first computing system, a second plurality of response packets to the first plurality of test packets over the network from the second computing system;
• determine, based at least in part on the first plurality of test packets and the second plurality of response packets, whether a mismatch exists between a network transmission media maximum transmission unit of the first computing system and a discovered path maximum transmission unit of the at least one path;
• in response to a mismatch existing, take a remediation action;
• and
• repeating the sending, receiving, determining and reducing until no mismatch exists.

An apparatus comprising:

• processing circuitry;
• and
• instructions that when executed by the processing circuitry cause the apparatus to:
• send, by a first computing system, a first plurality of test packets over at least one path in a network to a second computing system;
• receive, by the first computing system, a second plurality of response packets to the first plurality of test packets over the network from the second computing system;
• determine, based at least in part on the first plurality of test packets and the second plurality of response packets, whether a mismatch exists between a network transmission media maximum transmission unit of the first computing system and a discovered path maximum transmission unit of the at least one path;
• in response to a mismatch existing, take a remediation action;
• and
• repeating the sending, receiving, determining and reducing until no mismatch exists.
