2 September 1975

This is a working document which has been developed as the specification

and guideline for design of a Burroughs B6700 attachment to an ARPA-Style


The approach is to utilize a front-end processor with a new protocol for

network operation. That protocol, described herein, has been built upon

the concepts expressed by M.A. Padlipsky, et al, in NIC# 31117, RFC# 647.

This proposed, site-specific, FEP implementation is the work of Gerald

Bailey and Keith McCloghrie of NSA and of David Grothe of ACC. It has

already sustained some corrections provided by MAP. It will be helpful

if interested networkers will review and provide comments to us.

Front-End Protocol: B6700 Version




This document describes the protocol to be used for connecting a general-

purpose computer system (host) to an ARPANET-like network via a "front-end"

computer. The main body of the document is aimed at a reader who is not

conversant with all the details of network protocols. However, a paragraph

marked with [n], refers a reader familiar with network protocols to the

n-th item of Appendix A which will amplify that particular paragraph.

Further information on the network protocols referred to in this document

can be obtained from the Network Information Center.

Appendix B contains diagrams showing the transitions between the different

connection states. Appendices C and D give the implementation details of

this protocol in the Front-End and the Hosts.

This protocol is predicated upon the assumption that for each host, a line

protocol, at a lower level, will be established between the device-driver

modules in the Host and the Front-End, and that this line protocol provides

Front-End Protocol with error-free transmissions.


A host computer may be connected to a network for a variety of reasons.

Network connection may be an attempt to expand the usefulness of the

Host to the community of users which it serves by making network resources

available to them. Conversely, the services which the Host provides may

be made available to a larger community of users, with the network providing

the method of access to those services.

In order for members of a network community to communicate in an int...
