Performance Analysis of CoS of Bridged WorldFIP and ATM Networks for Real Time Communication

Abstract

The implementation of the remote control, monitoring and maintenance of industrial automation systems based on real-time criteria is becoming more difficult as the distance increases. ATM is an important transport, switching, network management and backbone technology that offers different solutions to real-time communication with different classes of service. In this study, the effects on real-time communication of AAL 3/4 and AAL 5 classes of service of ATM were researched on a model in which the communication between WorldFIP industrial network nodes and ATM network nodes was provided over a bridge. First, a communication system consisting of a WorldFIP network, ATM network and bridge were modeled on a simulation tool and implemented. Afterwards, the system performance was analyzed under different loads within the classes of service AAL 3/4 and AAL 5. The analysis results have indicated that compared to AAL 5, AAL 3/4 better satisfies the real-time communication criteria. This result has shown that in both real-time access to a remote industrial automation systems and communication among remote industrial automation systems, ATM is preferable as a backbone and AAL 3/4 as the class of service.

Gibbs Sampling in Inference of Copula Gaussian Graphical Model Adapted to Biological Networks

“…Additionally, we consider that similar strategies, used in RJMCMC and Gibbs sampling, can be adapted in time series chain graphical model [18], correct inference of which is conducted via the two-stage penalized maximum likelihood method. Finally, different methods suggested for different types of networks can be also adapted for the complex biological systems [19,20].…”

Application of Data Communication to the Detection and Correction of Power System Faults

“…Mainly, the protocol is picked up depending on some outlined criteria. One seeks to exchange data in fast manner regardless the reliability of some data whereas others claim to have the whole information content [16,17].…”
