The Effects of Non-Uniform Traffic Distribution in Switching Networks
نویسنده
چکیده
This paper deals with the phenomenon that in a switching network the individual link groups between any two stages do not have a uniform traffic load. Such a non-uniform load within the switching network can be due to the following causes: External causes: When subscribers and trunks are assigned to the switching network, uniform distribution of the load over the individual matrices is not achieved. Internal cause: The specific mode of operation of the switching control: The effect of non-uniformly loaded link groups on the grade of service is analyzed in fourstage switching networks composed of two-stage link blocks. This effect is always shown to be unfavorable. The influence of the externally caused non-uniform load on the grade of service of configurations employing the structure under consideration is intensified as the mean load of the links leaving the 1stand laststage matrices increases. With regard to the internal causes it is important for the switching control for outgoing traffic to be based on a suitable strategy.

The Assessment of Applying Chaos Theory for Daily Traffic Estimation
Road traffic volumes in intercity roads are generally estimated by probability functions, statistical techniques or meta-heuristic approaches such as artificial neural networks. As the road traffic volumes depend on input variables and mainly road geometrical design, weather conditions, day or night time, weekend or national holidays and so on, these are also estimated by pattern recognition te...

In this paper, a self-healing approach for smart distribution network is presented based on Graph theory and cut sets. In the proposed Graph theory based approach, the upstream grid and all the existing microgrids are modeled as a common node after fault occurrence. Thereafter, the maneuvering lines which are in the cut sets are selected as the recovery path for alternatives networks by making ...

Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation...
متن کاملTraffic Control in Wormhole Routing Meshes under Non-Uniform Traffic Patterns
Nonuniform traffic patterns can severely degrade the performance of wormhole-routing mesh networks in multiprocessor systems. For example, under a temporary hot-spot traffic, a saturation tree might build up temporarily within the network resulting in a temporary network overload that will delay messages substantially. To the knowledge of the authors, no mechanisms were proposed in the open lit...
