Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

In this paper, we give an overview and classification of optical burst switching schemes and present burst reservation concepts. The performance of various basic reservation mechanisms proposed in literature is compared. Furthermore, a new analysis is introduced that allows to calculate the loss probabilities of a two-class system based on the reservation mechanism just-enough-time (JET) for ar...

Scalable, hierarchical, all-optical WDM networks for processor interconnection in multiprocessor systems have been recently considered. The principal objective of this paper is to introduce an access protocol for this type of network which supports a distributed shared memory (DSM) environment. The objectives of the protocol are reduced averagelatency per packet, support of broadcast/multicast,...

DINAS is an interactive system to aid solving various multiobje~tive transshipment problems with facility focation using IBM-PC XT:AT or compatibles. DINAS utilizes the so-called aspiration-based (or reference point) approach to interactive handling of multiple objectives. In this approach the decision maker forms his/her requirements in terms of aspiration and reservation levels, i.e. specifie...

Modern high speed networks (and ATM networks in particular) use resource reservation as a basic means of establishing communications. One-way on-they reservation is a method for allocating resources for short bursts of data when regular reservation is too costly. The rst such algorithms were recently suggested by Turner. We investigate two examples that are characteristic to the way traac strea...

This paper investigates the performance of media access protocols based on on-line scheduling for an optically connected star-coupled system with Wavelength Division Multiple Access channels. Hybrid access protocols combining reservation and pre-allocation of receiver channels have been recently proposed. Transmission consisted of a reservation phase followed by a data phase. Each node was allo...

Demanding applications like distributed multi-physics simulations benefit from the combined computational performance and data storage of multiple clusters. A reservation mechanism spanning these clusters ensures the availability of all selected resources. Complex workflows with chronological dependencies are supported. This approach addresses network resources the same way as computation and s...

This paper studies the impact of resource reservation on the multi–path Quality–of–Service (QoS) routing schemes that use global network state to make routing decisions. Incorporating resource reservation into multi–path QoS routing algorithms greatly changes the communication characteristics in a network system and affects the performance of the routing algorithms. In this paper, we develop a ...
