<abstract>
<t>This memo describes the experiences of a project team at Cray Research, Inc., in implementing support for circuit-switched T3 services.  While the issues discussed may not be directly relevant to the research problems of the Internet, they may be interesting to a number of researchers and implementers.</t>
<t>Developers at Cray Research, Inc. were presented with an opportunity to use a circuit-switched T3 network for wide area networking.  They devised an architectural model for using this new resource.  This involves activating the circuit-switched connection when an application program engages in a bulk data transfer, and releasing the connection when the transfer is complete.</t>
<t>Three software implementations for this feature have been tested, and the results documented here.  A variety of issues are involved, and further research is necessary.  Network users are beginning to recognize the value of this service, and are planning to make use of by-request circuit-switched networks.  A standard method of access will be needed to ensure interoperability among vendors of circuit-switched network support products.</t></abstract></front>
