—Model checking is an important technique for ensuring the correctness of investigated system. However, the model checking tools subject to the state-space explosion problem, which is an ignored hurdle to the practical application of the technique. This paper presents a case study of model checking the business flow of retail banking System, through an(More)
In the protocol conformance testing, many existing test methods can effectively detect the possible faults of the implementation under test. However, it is difficult to diagnose the found faults in terms of the test results. This paper presents a diagnosable input/output (DIO) sequence, to differentiate a state from other states under a given condition. We(More)
This paper presents a two-tiered reliable application layer multicast (ALM) solution, called HRALM, to provide lossless ALM services. HRALM builds a domain-based multicast tree, and divides the members into two transport planes (i.e., Plane 1 and Plane 2) in terms of the tree. In any domain, the distance between each member and the domain header is below a(More)
