Abstract: A method, computer program product, and data processing system for effici ently discovering and storing path MTU information in a sending host are dis closed. In a preferred embodiment, two path MTU tables are maintained. One p ath MTU table contains MTU values corresponding to the first-hop routers ass ociated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs t o send information to a destination, it first consults the MTU table associa ted with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the se nding host consults the MTU table for the first-hop router on the path to th e destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.
