Abstract
The invention concerns the technical field of a so-called Path MTU (Maximum Transmission Unit) Discovery process between two computing nodes over packet switched networks. On the path between two hosts (H1, H2, H3) in the network may exist various hops, e.g. routers (R1, R2), a packet needs to pass. Each link between two hops has its own MTU which may differ on each link. Some path MTU discovery algorithms are based on sending probe packets with the DF (don't fragment) bit set in the IP header. However, security devices, e.g. firewalls, often block ICMP messages, including the ICMP error messages that are needed for these path MTU discovery algorithms to work.
