ABSTRACT:
A method, system and apparatus for reducing dataflow disruption when increases in path maximum transmission unit (PMTU) are being detected are provided. Conventionally, when increases in PMTU are being detected, an increased-in-size data packet is sent by a transmitting host. If an intermediate link is unable to process the data packet through, it drops the data packet and sends an error message to the transmitting host. The transmitting host has to reduce the size of the data packet and resend it. The procedure outlines in this disclosure obviates the need to resend the data packet. It does so by transmitting an old data packet that has been increased in size. Hence, there is no need to resend the data packet if it is dropped.
