MTU Discovery

MTU Discovery is a process that helps devices determine the largest packet size they can send over a network without needing to be broken into smaller pieces. This ensures efficient data transfer by avoiding packet fragmentation, which can slow down communication and cause errors. Devices use techniques like sending test packets to find this maximum size, adjusting accordingly. Effective MTU Discovery improves network performance and reliability by ensuring data packets are optimized for the specific connection, reducing unnecessary delays or data loss.
