Modeling and validation of execution of tasks on high speed network under distributed environment

Abstract

During the past years, distributed computing approach has become an integral part of many of the software companies. This is because of low cost infrastructure involvement and faster execution of the tasks, sharing of resources, etc. In the year 2009, the Indian Government has established distributed network called as National Knowledge Network (NKN). The main objective of NKN is to connect all of the Indian universities, research institutions, computing labs, digital libraries, countrywide classrooms, etc. In the present paper, a well-known object-oriented Unified Modeling Language (UML) is used to construct a model for the execution of the tasks across a distributed network. Authors have designed a static step topology for the faster execution of tasks. Static and dynamic behaviors of the execution of the tasks are represented through UML class and state diagrams, respectively. For validation of the UML model, the state diagram is converted into a Finite State Machine (FSM) and different test cases are generated to validate the proposed model across distributed network environment.
