Abstract
This memo describes an experimental protocol developed by a project
team at Cray Research, Inc., in implementing support for circuit-
switched T3 services. The protocol is used for the control of
network connections external to a host, but known to the host. It is
documented here for the benefit of others who may wish to perform
further research.
While working with circuit-switched T3 networks, developers at Cray
Research, Inc., defined a model wherein a host would generate control
messages for a network switch. This work is described in RFC 1306,
"Experiences Supporting By-Request Circuit-Switched T3 Networks". In
order to simplify the model it was decided that the inconsistencies
of switch control should be hidden from the host generating the
control messages. To that end, a protocol was defined and
implemented. This RFC documents the Dynamically Switched Link
Control Protocol (DSLCP), which is used for creation and control of
downstream network links by a host.
1.0 INTRODUCTION
The Dynamically Switched Link Control Protocol (DSLCP) allows a host
with knowledge of a special downstream network link to issue messages
to control the status of that link.
This document describes the functions of the DSLCP to control
external network connections.
