Abstract

See full text

An example method is provided for a first device to perform reverse path maximum transmission unit (PMTU) discovery in a communications network. The method may comprise receiving multiple fragments of a packet sent by a second device via a path from the second device to the first device in the communications network. Based on the received fragments, a reverse PMTU that represents an estimate of a PMTU of the path from the second device to the first device may be determined. The method may further comprise configuring a message that includes data relating to the reverse PMTU and sending, to the second device, the message to inform the second device to size packets for transmission from the second device to the first device based on the data relating to the reverse PMTU.
