In this paper, a new and eecient Markov chain model for evaluating the performance of ATM switching fabrics based on multistage switches with 2 2 nite output-buuered SEs is proposed. By comparing the results obtained from the proposed model, previous models and simulations, it has been shown that the proposed model is much more accurate than previous models in the presence of a non-uniform traa...

In this paper an attempt has been made to analyze the characteristics of a new class of irregular fault-tolerant multistage interconnection network named as irregular modified augmented baseline network(IMABN).IMABN can provide ‘Full access’ capability in presence of multiple faults . Permutation passibility and Bandwidth Analysis shows that Proposed IMABN achieve a significant improvement over...

All-to-all personalized exchange is one of the most dense collective communication patterns and occurs in many important parallel computing/networking applications. In this paper, we look into the issue of realizing all-to-all personalized exchange in optical multistage networks. Advances in electro-optic technologies have made optical communication a promising networking choice to meet the inc...

Under the information and knowledge economy era, strengthening the enterprise strategic management can realize its sustained development in the intense market competition environment, increase its ability of adapting environment, and enhance the competitive strength and the competitive advantage. To evaluate the enterprise strategic management performance (ESMP) scientifically and accurately, t...

The composition of two pattern restricted classes X,Y is the set of all permutation products θφ where θ ∈ X,φ ∈ Y . This set is also defined by pattern restrictions. Examples are given where this set of restrictions is finite and where it is infinite. The composition operation is studied in terms of machines that sort and generate permutations. The theory is then applied to a multistage sorting...

Methods for simulating multistage interconnection networks using massively parallel SIMD computers are presented. Aspects of parallel simulation of interconnection networks are discussed and different strategies of mapping the architecture of the network to be simulated onto the parallel machine are studied and compared. To apply these methods to a wide variety of network topologies, the discus...

Multistage Interconnection Networks (MINs) are very popular in switching and communication applications. A MIN connects N inputs to N outputs and is referred as an N × N MIN; having size N. Optical Multistage Interconnection Network (OMIN) represents an important class of Interconnection networks. Crosstalk is the basic problem of OMIN. Switch Conflict and Link Conflict are the two main reason ...

The Multistage Interconnection Network with Cache control mechanism (MINC) is a hardware mechanism to control the cache coherent in a switchconnected multiprocessors using a crossbar or Multistage Interconnection Network(MIN). In the MINC, the directory is located on the shared memory module, and the Reduced Hierarchical Bit-map Directory schemes(RHBDs) are used to reduce the directory. In orde...

Nonuniform traffic can degrade the overall performance of multistage interconnection networks substantially. In this paper, this performance degradation is traced back to blocking effects that are not present under uniform traffic patterns within a network. This blocking phenomenon is not mentioned in the literature and is termed higher order Head-of-Line-blocking (HOLk-blocking) in this paper....
