Abstract: A computer-implemented method for facilitating communications between two peer nodes in a network. The method comprises (a) configuring a first of the peer nodes to transmit a Path Maximum Transmission Unit (PMTU) request to a second of the peer nodes; wherein the PMTU request comprises a PMTU test value; (b) configuring the second peer node to transmit a PMTU reply responsive to receiving the PMTU request; said PMTU reply comprising a PMTU value set to match the PMTU test value in PMTU request; and (c) configuring the first peer node to determine a PMTU for the network based on determinations of fragmentation in connection with the PMTU reply.
