Members of the Advanced Networking Group have written a number of papers and presentations, most of which focus on wide-area IP/ATM networks.
Chinoy, B. and Salo, TJ. "Internet Exchanges: Policy-Driven Evolution" June, 1996.
Abstract: Internet exchanges are systems within the Internet that enable networks to meet and exchange data and control information. This paper explores the interaction between Internet exchanges (IXs) and a variety of policies. IXs not were only influenced by external policies, but they often stimulated, enabled, shaped or even thwarted policies.
Cavanaugh, JD. "Protocol Overhead in IP/ATM Networks," August, 1994. (PostScript)
Abstract: This paper discusses the sources of protocol overhead in an IP/ATM protocol stack. It quantifies the amount of overhead and makes some observations about its effects. It shows that an application is limited to 87% or less of the line speed in an IP-over-ATM environment, that most of the protocol overhead is due to the lower levels of the protocol stack, and that MTU size can have a significant effect on the amount of protocol overhead.
Cavanaugh, JD and TJ Salo. "Internetworking with ATM WANs," December, 1992. (PostScript)
Abstract: High-speed (155-622 Mbps) wide-area networks based on the Broadband Integrated Services Digital Network's (B-ISDN) Asynchronous Transfer Mode (ATM) technology are currently being tested, and commercial service offerings are expected soon. This paper is an overview of ATM, ATM adaptation layers, and the Connectionless Broadband Data Service (CBDS). It discusses internetworking strategies and issues that arise when using ATM networks to carry the TCP/IP protocol suite.

Thomas, JP, JD Cavanaugh, and TJ Salo. "Design of a Very High-Speed Remote File System", December, 1992. (PostScript)
Abstract: A new application for gigabit networks, the network supercomputer, is described. Requirements for a very high-speed remote file system to support the network supercomputer are given, and a high-level design is described which meets those requirements.
Spengler, MK, and TJ Salo. "Technologies for Gigabit Distributed File Systems", December, 1992. (PostScript)
Abstract: Gigabit-per-second wide-area networks will soon be moving out of the research laboratories. A model for one use of these networks, the network supercomputer, is presented. A key component of the network supercomputer is its data sharing service. This paper discusses the requirements for such a service and provides an analysis of the current technologies available for its implementation.
Hsieh, Jenwei, DHC Du, JA MacDonald, JP Thomas, JT Pugaczewski, J Kays, and M Wiklund. "Experimental study of Extended HIPPI Connections over ATM Networks," March, 1996. (PostScript)
Abstract: To extend the widespread use of HIPPI as a networking solution for high-speed communications, the 25-meter distance limitation must be solved. Three options available for alleviating the problem of distance limitation of HIPPI networks are serial-HIPPI, HIPPI/SONET mapping or HIPPI-ATM mapping, and IP routing. Serial-HIPPI, HIPPI/SONET mapping, and HIPPI-ATM mapping provide extended HIPPI connectivity at the physical layer, while IP routing forwards data between HIPPI networks and other networks at the network layer. In this paper, we study two feasible solutions of this problem, HIPPI tunneling (HIPPI-ATM mapping) and IP routing. We compare these two schemes in terms of network connectivity, protocol overhead, and flow control. The performance evaluation of one implementation of the HIPPI tunneling and IP routing is presented. Experimental performance suggests that a high degree of bandwidth utilization was achieved by both HIPPI tunneling and IP routing in this implementation.

Lin, M, DHC Du, JP Thomas, and JA MacDonald. "Distributed Network Computing over Local ATM Networks," IEEE Journal on Selected Areas in Communications, Vol. 13, no. 4, May 1995, pp. 733-748. (PostScript)
Abstract: The authors investigate distributed network computing over local ATM networks. Four APIs were used: Fore Systems' ATM API, the BSD socket programming interface, Sun's Remote Procedure Call (RPC), and the Parallel Virtual Machine (PVM) message passing library. Two popular distributed applications were evaluated, parallel Matrix Multiplication and parallel Partial Differential Equations, over the local ATM network. The experimental results show that network computing is promising over local ATM networks, provided that the higher level protocols, device drivers, and network interfaces are improved.
Midani, MT, A Guha, JD Cavanaugh, and JT Pugaczewski. "Interoperability Considerations Between ATM Equipment Based on the B-ISDN COMPASS/Mercuri Trial," September, 1994. (PostScript)
Abstract: The B-ISDN COMPASS Project Mercuri Trial involved the interconnection of ATM equipment from three different vendors, which the authors found to be surprisingly difficult. This paper explains the technical challenges and difficulties we encountered and suggests a set of recommendations which, if observed, should make the process of interconnecting ATM equipment from different vendors more likely to succeed. At the physical (SONET) layer, we discuss optical signal level, connector type, ATM cell delineation (which turned out to be one of the most troublesome problems in the trial), SONET payload type indication and test equipment. At the ATM layer, we discuss the idle cell format (which also proved quite troublesome), VPI/VCI fields, ATM OA&M functions, and ATM signalling. At the application layer, we briefly describe the protocol stack.
