IPv6 is designed to address the scalability and service shortcomings of the current IPv4 protocol. Unfortunately, IPv6 is not backward-compatible with the IPv4. It is necessary to consider IPv4-IPv6 protocol conversion. To resolve this problem, in the paper, we use Petri nets to simulate and model the IPv4-Pv6 protocol conversion process. By analyzing the bounded ness, activity and reversibility of...
We present a new symbolic approach for thesteady-state solution of ergodic continuous-time Markov chains(CTMCs) using iterative methods, based on Edge-Valued Multi-way Decision Diagrams (EVMDDs) to store an indexing function for the structured states and the transition rate matrix. The approach is applicable to any structured CTMC, is memory efficient, and supports both Jacobi and Gauss-Seidel iterations...
Witness generation is a fundamental model checker feature, but generating shortest witnesses for an EG CTL formula has long been a difficult problem of both theoretical and practical relevance. We propose a symbolic approach to shortest EG witness generation based on edge-valued multi-way decision diagrams. We employ a fix point symbolic iteration to compute the transitive closure enhanced with distance...
