  • An Object-Oriented approach in C++ for asynchronous processing in CMISE-applications

    Publication Year: 1995, Page(s):366 - 372

    This paper introduces a set of C++ classes which provide a framework for development of CMISE-applications. The nature of processing that is common to all CMISE-applications is abstracted in interdependent base classes. These classes are designed so that application-specific requirements are met without the necessity of modifying existing code: open to specific requirements but closed to modificat...

    Future networking environments are expected to provide more bandwidth and be more robust to bit errors. Such changes will pose new requirements for data transfer protocols. Rather than trying to adapt an existing transport protocol to this new environment, we decided to develop a new one called RAPID. The most important features of RAPID are its unidirectional data transfer capability and a clear ... View full abstract»

    Recently R.N. Draper (1990) initiated the study of interconnection networks based on Cayley graphs of semi-direct products of two cyclic groups called supertoroids graphs. Interest in this class of graphs stems from their relatively smaller diameter compared to toroids of the same size. In this paper we described a deterministic, distributed, shortest path algorithm for routing in this class of ne... View full abstract»

    We present techniques for the rapid estimation of very low (10-12 to 10-20) bit-error-rate (BER) in electrical and optical digital data links. Approximately 2 minutes elapsed time is required to perform a low BER test, independent of the actual BER value being measured. There are two types of applications: (1) confirming very low BER (<10-12) performance, and (2... View full abstract»

    Synchronization is essential to the effective operation of telecommunications networks. Digital switching and transmission systems implemented in telecommunications networks today require synchronization to improve efficiency and prevent impairments. The essential role of synchronization in telecommunications networks is often misunderstood. Some of the methods typically used by the Bellcore Clien... View full abstract»

    In this paper, we propose a top-down method for constructing optimized protocol converters to achieve interoperability between heterogeneous computer networks. This method first generates a converter from a given service specification of the internetworking system and two protocol specifications, based on two important concepts: controllability and observability. The reduction relation is used to ... View full abstract»

    The interconnection of LAN/MANs to ATM networks is important for supporting connectionless (CL) applications geographically. Given that conventional flow control mechanisms have been eliminated to improve switching speeds, admission control will be crucial for an ATM network to protect itself from congestion. Since ATM networks are connection-oriented (CO) by nature, current admission control sche... View full abstract»

    The MP-tree (Multi-dimensional Persistent tree), a data structure for managing spatio-temporal data, is proposed. The MP-tree is developed by extending conventional spatial data structures using techniques of Persistent Search Tree. In this paper, the structure and operations of the MP-tree are described and the performance of the MP-tree is compared with three possible methods. Through computer s... View full abstract»

    This paper explores an attribute-based approach to storing information in the context of a file system that supports extended attributes about files and a mechanism to manipulate files based on logical queries and comparisons of attributes. The novel aspects of our system are that it is sophisticated enough to operate as a user's primary method of interaction with the operating system and that it ... View full abstract»

    Several computer graphics algorithms (such as ray-tracing) heavily relate their performances to the efficiency of the tests of intersection between the rays of a light source and the objects of a synthetic scene. Some solid modeling and robotics algorithms need also to test quickly the possible interferences of the different parts of a system such as the arms of different robots. To speed-up the t...

    As data rate demands on existing satellite systems increase, the need to evaluate more bandwidth efficient modulation schemes such as M-ary phase Shift Keying (MPSK) becomes important. However, the unavailability of higher order modems operational at higher data rates and the construction of such a complex device for testing purposes can make evaluation difficult. In support of NASA grant NAG 5-14... View full abstract»

    The purpose of this paper is to assess the match between algorithms and MIMD parallel architectures from the perspective of resource requirements and resource supplies. In the Extended Evaluation Framework, three figures of merit (FOM1, FOM2 and FOM3) are proposed as measures of the match. FOM1 shows the time average of the sum of weighted resource to re...

    High-end microprocessors now tend to be superscalar, to execute operations out of order, and to support shared memory among multiple processors. Verifying the functionality of such a microprocessor using simulation requires many stages, from tests of simple portions of the design, through simple tests of a single processor to complex tests of multiple processors. We followed this strategy using so... View full abstract»

    In this paper, we present the performance of a dual bus reservation based (DBRB) access protocol, for high speed local and metropolitan area networks. The DBRB network consists of unidirectional dual bus topology of fiber optic cables. At each end there is a master station which generates a frame of slots. When a station wants to transmit, it has to make a reservation in a frame on one bus and wai... View full abstract»

    The paper discusses the traffic distortion suffered by a periodic source at an ATM multiplexer, in the presence of interfering ON-OFF sources. We analyze a FIFO queue that serves the superposition of the periodic source and background traffic to obtain the jitter density. Traffic distortion is not limited to periodic sources alone. We relax the requirement of periodicity and investigate the jitter... View full abstract»

    The ANSI/X3/SPARC architecture is a basic component of the database technology. Conceptual modeling is a major element of database design. After twenty years of use a contrasted evaluation can be done. Formalisms, design techniques and mappings represent very different interpretations of the proposed architecture. Most of the time, naturalness and intuition are the guidelines for an easy conceptua... View full abstract»

    The maximum allowed number of faulty processors in an n-dimensional hypercube system is n under PMC model for diagnosis. When the n fault bound is adopted, all links will be used to perform diagnosis. However, if the fault bound is lower than n, many links can be freed from the task of performing diagnosis. In this paper, we show that each drop of the fault bound by 1 can free 2n-1 link... View full abstract»

    Regular Cayley graphs like hypercubes and recently introduced star graphs play an important role in designing interconnection networks for multiprocessing systems; these graphs are regular and the degree of the nodes increases with the size of the graph (the number of nodes) either logarithmically or sub logarithmically. But, from a VLSI design point of view, constant degree networks are more suit... View full abstract»
