    This paper presents the results of an investigation of the relationship between the occurence intensity of different failures in the fault-tolerant control system of three SPC (stored-program control) telephone exchanges and various activity dependent factors in the real time environment of the exchanges. The analysis is based on 475, 439, and 243 failure registrations during 85, 71, and 64 months... View full abstract»

    This paper presents a model to calculate the reliability of communication networks with multimode components. Previous research on network reliability has focused on models in which each component may be in one of two modes, namely, operative or failed. In reality, a component may undergo degradations in performance before a complete outage, and will therefore operate in more than two modes. Tradi... View full abstract»

  • A Timeout-Based Congestion Control Scheme for Window Flow-Controlled Networks

    During overload, most networks drop packets due to buffer unavailability. The resulting timeouts at the source provide an implicit mechanism to convey congestion signals from the network to the source. On a timeout, a source should not only retransmit the lost packet, but it should also reduce its load on the network. Basedon this realization, we have developed a simple congestion control scheme u... View full abstract»

    This paper postulates an avionics maintenance concept for the year 2010. The concept recognizes the change that is occurring in new systems toward internal fault isolation using built-in test. Currently, fault isolation data are held in the failed system or within the aircraft computer for subsequent analysis by maintenance personnel. Under the Maintenance 2010 concept, fault data would be analyze... View full abstract»

    Despite their diversity, the many factors that enter into the way the quality of telecommunications software is perceived can plainly be linked to the process by which the software is developed. This is fortunate, since the quality of the process is the more easily quantified. In focusing quality programs for telecommunications software on its development, we see that the quality of the final prod... View full abstract»

    Permanent and temporary faults can be subdivided into classes with respect to their properties in the electrical domain and the time domain, e.g., sudden solid, marginal, gradual, intermittent. Strategies in the design of the central control of the AXE digital switching system are described. The automatic locating of permanent and temporary faults is based on a modular hardware architecture and st... View full abstract»

    The software/hardware is available now to quickly construct very large networks. These networks contain various layers of connectivity with the possibility of different vendors providing each layer. Each layer may have its own means of operator management and control. The growth of these networks is starting to outstrip the ability of network operators to effectively recognize and attack problems.... View full abstract»
