Work on standardization of OSI routeing protocols has already started. A route-ing framework deening the functional components of the routeing problem was published. This paper discusses the OSI routeing problem and presents the addressing and routeing ar-chitectures used to solve it. It also gives some comments on the proposed routeing protocols, focusing on the need of a network layer Directo...

Searching for vacant parking spaces is a time-consuming and often irritating task. Car park routeing systems can assist drivers in this undertaking. Current parking systems either issue imprecise information or prove costly due to the required resources, and are thus unattractive for car park operators. In this paper, we propose a vehicle tracking and navigation module as part of a routeing sys...

We believe that the control currently provided by routeing in the Internet is becoming demonstrably insufficient for the demands of network operators and users. Current routeing protocols provide little or no support for automation of network management, leaving such things as construction and implementation of SLAs and the pricing of resources entirely to the network manager. The research prop...

To analyse an automated guided vehicle (AGV) system operating under selected vehicle routeing strategies, we present a simulation model that can handle an arbitrary system layout as well as arbitrary numbers of AGVs and pedestrians causing congestion in the system. We introduce a dynamic vehicle routeing strategy based on hierarchical simulation that operates as follows: at the time of each AGV...

This paper discusses the modelling of rainfall-flow (rainfall-run-off) and flow-routeing processes in river systems within the context of real-time flood forecasting. It is argued that deterministic, reductionist (or 'bottom-up') models are inappropriate for real-time forecasting because of the inherent uncertainty that characterizes river-catchment dynamics and the problems of model over-param...

Jobs from a single Poisson input stream receive K independent stages of service, one at each stage in the pipeline. At stage i jobs are routed through one of the Ni available nodes, modelled as M/M/1 queues. These nodes are subject to random failure and repairs which leave their corresponding queues intact, but may affect the routeing of jobs arriving at that stage during the subsequent repair ...

The Internet’s inter-domain routeing system has evolved to keep pace with the Internet’s rapid growth, from a few co-operatively managed administrative domains to a large number of competetive domains. This growth has brought to light one of the Internet’s shortcomings: lack of support for efficient control and management of traffic, particularly between domains. This paper presents an extensio...

For exponential open and closed queueing networks, we investigate the internal dependence structure, compare the internal dependence for different networks, and discuss the relation of correlation formulae to the existence of spectral gaps and comparison of asymptotic variances. A central prerequisite for the derived theorems is stochastic monotonicity of the networks. The dependence structure ...

The deployment of optical fibers with the emergence of the ATM technology which relies on a Virtual Call (VC) model is the necessary infrastructure to support modern applications such as multimedia. In this paper, we propose to extend the classical method for packet switching, namely the distance vector and the link state method to cover these new user requirements. We present an ATM routeing a...
