Assessing and monitoring the performance of computer and communications networks is an important problem for network engineers. There has been a considerable amount of work on tools and techniques for data collection, modeling, and analysis within the network research community. The goal of this paper is to present an overview of the engineering problems(More)
Static program analysis uses many checkers to discover a very large number of programming issues, but with a high false alarm rate. With the aid of dynamic automatic testing, the actual severe defects can be confirmed by failures of test cases. After defects are fixed, similar types of defects tend to reoccur again. In this paper, we propose a SoftWare(More)
A notification service alerts a large number of recipients to attend to important or emergency events. Prompt notification using multiple modes is critical to handle a disaster. This paper proposes an "escalation hierarchy" method as an enhancement to the combinatorial testing approach to provide capacity evaluation of a notification service involving(More)
