ABSTRACT:
A process and apparatus are disclosed wherein a local data terminal equipment ("DTE" ) node which has the capability of using RFC 1144 TCP/IP header compression/decompression, can negotiate with an unknown remote DTE located at another end of a TCP/IP/X.25 network link, to determine if the remote DTE also supports RFC 1144 TCP/IP header compression/decompression. The disclosed apparatus and process permits a user (such as a systems administrator, for example) to instruct the local DTE that a remote DTE is known to support TCP/IP header compression/decompression whereby the local DTE sets its routing information to record this information. Alternatively, the local DTE can automatically query an unknown remote DTE to determine if it supports TCP/IP header compression/decompression and set its routing information accordingly.
