In ATM networks, traffic control design becomes an important challenge, because of the diverse services support and the need for efficient network resource engineering. Two important functions for traffic control in ATM networks are policing and routing. The goal of these two functions is to guarantee the required quality of service. So far, all studies have treated policing and routing in a separate way. The combination of policing and routing can guarantee a better quality of service and increase the network utilization. Traditional network control strategies are not well suited for high speed networks. Use of intelligent algorithms based on fuzzy logic, neural networks and genetic algorithms can prove to be efficient for traffic control in ATM networks. We propose an intelligent policing-routing mechanism based on fuzzy logic and genetic algorithms. Performance evaluation via simulations shows that the proposed mechanism performs better than conventional policing mechanisms and routing algorithms.","PeriodicalId":226947,"journal":{"name":"Proceedings 1998 International Conference on Parallel and Distributed Systems (Cat.

We present a generalized basic cycle calculation (GBCC) method to efficiently perform a BLOCK-CYCLIC(s) over P processors to BLOCK-CYCLIC(t) over Q processors array redistribution. In the GBCC method, a processor first computes the source/destination processor/data sets of array elements in the first generalized basic cycle of the local array it owns. A generalized basic cycle is defined as lcm(sP,tQ)/(gcd(s,t)/spl times/P) in the source distribution and lcm(sP,tQ)/(gcd(s,t)/spl times/Q) in the destination distribution. From the source/destination processor/data sets of array elements in the first generalized basic cycle, we can construct packing/unpacking pattern tables. Based on the packing/unpacking pattern tables, a processor can pack/unpack array elements efficiently. To evaluate the performance of the GBCC method, we have implemented this method on an IBM SP2 parallel machine, along with the PITFALLS method and the ScaLAPACK method. The cost models for these three methods are also presented. The experimental results show that the GBCC method outperforms the PITFALLS method and the ScaLAPACK method for all test samples. A brief description of the extension of the GBCC method to multi dimensional array redistributions is also presented.","PeriodicalId":226947,"journal":{"name":"Proceedings 1998 International Conference on Parallel and Distributed Systems (Cat.

There are similarities involved in accessing information in a multidatabase environment and a mobile computing environment. We have discussed the characteristics of a wireless-mobile computing environment superimposed on a multidatabase system to realize a system capable of effectively accessing a large amount of data over a wireless medium. In order to limit the effects of the restrictions imposed by a mobile environment, data duplication is used at the mobile unit. The duplicated data at the mobile node provide additional availability in case of a weak connection or disconnection. In such an environment, it is important to retain the consistency between the data residing on fixed nodes and mobile nodes. Current research has concentrated on page- and file-based caching or replication schemes to address the availability and consistency issues in a mobile environment. In a mobile multidatabase environment, local autonomy restrictions prevent the use of a page- or file-based data duplication scheme. We propose a new data duplication scheme to address the limited bandwidth and local autonomy restrictions in such an environment. Queries and their associated data are cached at the mobile unit as a complete object. Consistency is maintained by using a parity-based invalidation scheme. Additionally, a simple prefetching scheme is used in conjunction with caching to further improve effectiveness of the proposed scheme.","PeriodicalId":226947,"journal":{"name":"Proceedings 1998 International Conference on Parallel and Distributed Systems (Cat.
