Desarrollar un algoritmo de control de flujo eficaz para evitar la congestión es un tema candente en la sociedad de redes de computadoras. Este artículo ofrece en principio un modelo matemático para una red general y luego se propone la teoría de control discreto como la herramienta clave para el diseño de un nuevo algoritmo de control de flujo para evitar la congestión en una red de alta velocidad; el algoritmo propuesto asegura la estabilidad del sistema de red. Los resultados de simulación muestran que el método propuesto puede ajustar la tasa de envío y el nivel de la cola en buffer de forma rápida y efectiva. El método es fácil de implementar y aplicar en una red de computadoras de alta velocidad. Palabras clave: Congestión, control de flujo, redes de computadoras de alta velocidad.
Process equivalences are formal methods that relate programs and system which, informally, behave in the same way. Since there is no unique notion of what it means for two dynamic systems to display the same behaviour there are a multitude of formal process equivalences, ranging from bisimulation to trace equivalence, categorised in the linear-time branching-time spectrum. We present a logical framework based on an expressive modal fixpoint logic which is capable of defining many process equivalence relations: for each such equivalence there is a fixed formula which is satisfied by a pair of processes if and only if they are equivalent with respect to this relation. We explain how to do model checking, even symbolically, for a significant fragment of this logic that captures many process equivalences. This allows model checking technology to be used for process equivalence checking. We show how partial evaluation can be used to obtain decision procedures for process equivalences from the generic model checking scheme
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
