  • a context Resolution Server for the galaxy conversational systems
    Conference of the International Speech Communication Association, 2002
    Co-Authors: Edward Filisko, Stephanie Seneff
    Abstract:

    The context Resolution (CR) component of a conversational dialogue system is responsible for interpreting a user’s utterance in the context of previously spoken user utterances, spatial and temporal context, inference, and shared world knowledge. This paper describes a new and independent CR Server for the GALAXY conversational system framework. Among the functionality provided by the CR Server is the inheritance and masking of historical information, pragmatic verification, as well as reference and ellipsis Resolution. The new Server additionally features a process that attempts to reconstruct the intention of the user given a robust parse of an utterance. Design issues are described, followed by a description of each function in the context Resolution process along with examples. The effectiveness of the CR Server in various domains attests to its success as a module for context Resolution.

  • WORDS - An architecture for a tightly coupled conferencing system
    Proceedings Third International Workshop on Object-Oriented Real-Time Dependable Systems, 1997
    Co-Authors: A. Sangjoon
    Abstract:

    Describes an architecture for a tightly coupled conferencing system on an asynchronous transfer mode (ATM) network. In order to provide multicast service, we construct a multicast environment using a multicast address Resolution Server (MARS) and multicast Servers (MCSs). The architecture provides conference control services which provide tight coordination of conference membership over the environment. The services are provided by a conference control Server (CCS). We propose a secondary CCS in order to support fault tolerance. When the primary CCS fails to perform its service, the secondary CCS rakes over the control and continues conferencing without stopping.

  • HICSS - A multicasting scheme using multiple MCSs for reducing end-to-end path delay in ATM networks
    Proceedings of the 33rd Annual Hawaii International Conference on System Sciences, 2000
    Co-Authors: Tae-young Byun
    Abstract:

    In this paper, we surveyed existing implementation experiences related to multicast address Resolution Server (MARS) and multicasting Server (MCS) supporting IP multicast over an ATM network. We also proposed two models, fully multiple MCS model and hybrid multiple MCS model, to support multiple MCSs over a single large cluster in ATM networks, and evaluated the performance of the fully multiple MCS model by simulation. When an ATM host requests joining a specific multicast group, the MARS designates a proper MCS among the multiple MCSs for the group member to minimize the average path delay between the sender and the group members. This scheme constructs a two-phase partial multicast tree based upon the shortest path algorithm. We reduced the average path delay in the multicast tree using this scheme with various cluster topologies and MCS distribution scenarios, and also distributed load uniformly among multiple MCSs.

  • Network design for streaming service on IP multicast over ATM
    Electronics and Communications in Japan Part Ii-electronics, 2003
    Co-Authors: K. Sugisono, M. Yamamoto, H. Ikeda
    Abstract:

    This paper considers streaming service, which is an application of multicast communications, and discusses the network configuration used in providing IP multicast over ATM. In IP multicast over ATM, conversion from the IP multicast address to the ATM address is required. One of the methods of making this conversion is to use a multicast address Resolution Server (MARS). In this system, the MARS manages the member information of the multicast group. When there is a change in the membership of the group because a host joins or leaves, that host sends an information renewal message to the MARS. In streaming service, there arises a time zone in which many renewal messages to MARS are generated due to program changes and the like, so that the MARS is heavily burdened. This paper considers the case in which streaming service is introduced via MARS, and analytically derives the transmission frequency of the information renewal messages. The relations between the transmission frequency, the characteristics of the program, and the network scale are identified. Based on the results of analysis and a consideration of the effect of other traffic on the network, an adequate network design principle capable of reducing the control traffic to the MARS is presented. © 2003 Wiley Periodicals, Inc.

  • MARS load analysis of streaming service on IP multicast over ATM
    Conference Proceedings of the 2000 IEEE International Performance Computing and Communications Conference (Cat. No.00CH37086), 2000
    Co-Authors: K. Sugisono, M. Yamamoto, H. Ikeda
    Abstract:

    The Internet is now a widely used network and is expected to accommodate many kinds of services in an integrated manner. One of these promising services is a streaming service such as video or radio streaming. In the Internet, this streaming service should be supported by multicast communications, i.e. IP multicast, in order to reduce total bandwidth necessary for distributing streaming programs. In future network infrastructure, ATM technology should be implemented in a backbone network. So, in order to integrate opposite-side two network architecture. IP and ATM, IP Multicast over ATM technology is proposed in IETF. In this technology, Multicast Address Resolution Server (MARS) is used for address Resolution generally. On changing group membership, MARS receives control message informing membership change from ATM end points, edge routers. Multicast group may grow up to thousands of recipient in the case of streaming service. Overload of MARS due to message concentration is one of the most serious problems for streaming service in the Internet. In this paper we analyze load for MARS brought by control message according to multicast group management for streaming service. With numerical results, we discuss about suitable network configuration for scalable streaming service.
