Abstract

This document specifies the Host Access Protocol (HAP). Although HAP was originally designed as the network-access level protocol for the DARPA/DCA sponsored Wideband Packet Satellite Network, it is intended that it evolve into a standard interface SATNET and TACNET (aka MATNET) as well as the Wideband Network. HAP is an experimental protocol, and will undergo further revision as new capabilities are added and/or different satellite networks are suported. Implementations of HAP should be performed in coordination with satellite network development and operations personnel.

RFC 907 Host Access Protocol July 1984 Specification

Preface (Status of this Memo)

This document specifies the Host Access Protocol (HAP). Although HAP was originally designed as the network-access level protocol for the DARPA/DCA sponsored Wideband Packet Satellite Network, it is intended that it evolve into a standard interface between hosts and packet-switched satellite networks such as SATNET and TACNET (aka MATNET) as well as the Wideband Network. The HAP specification presented here is a minor revision of, and supercedes, the specification presented in Chapter 4 of BBN Report No. 4469, the "PSAT Technical Report". As such, the details of the current specification are still most closely matched to the characteristics if the Wideband Satellite Network. Revisions to the specification in the "PSAT Technical Report" include the definition of three new control message types (Loopback Request, Link Going Down, and NOP), a "Reason" field in Restart Request control messages, new Unnumbered Response codes, and new values for the setup codes used to manage streams and groups.

HAP is an experimental protocol, and will undergo further revision as new capabilities are added and/or different satellite networks are supported. Implementations of HAP should be performed in coordination with satellite network development and operations personnel.
