better suited for a secure net. He discusses the handling of "ports" as capabilities (in an access control sense) but does not consider the potential problems of controlling the establishment of end-to-end communications paths (i.e., setting up the encipherment keys). Since the "connections" in his scheme would only exist for the flow of one message, the dialog-oriented approach that we have taken for the SC might not apply. In contrast, the current ARPA net protocol is connection-oriented (a connection is created by control commands for use during a dialog) and therefore seems to fit well with our scheme. However, the intuitive appeal of using a message-oriented protocol for a message-switched network deserves additional attention.

Specifically noted were the Walden
Message-Switching Protocol, ARPA H-H Protocol, NPL High-Level Protocol, CYCLADES Protocol, and EPSS Protocol.... Perhaps the only historical difference that would have occurred if DARPA had switched to the INWG 96 protocol is that rather than Cerf and Kahn being routinely cited as "fathers of the Internet," maybe Cerf, Scantlebury, Zimmermann, and I would have been.

At the New York meeting, a small team of engineers (E. Aupperle, V. Cerf, B. Kahn, A. McKenzie, R. Metcalfe, R. Scantlebury, et al.) with implementation experience in ARPANET (US), Cyclades (F), MERIT (US), and NPL (UK) created a first draft of an
International Transmission Protocol (ITP). ...
