Evaluation of multi-layer recovery strategies
نویسندگان
چکیده
Modern broadband telecommunication networks are based on multiple transport technologies such as Asynchronous Transfer Mode (ATM), Synchronous Digital Hierarchy (SDH) and Wavelength Division Multiplex (WDM). For resilient networks, recovery mechanisms are existent in each technology. The coordination or interworking aspects of the single layer recovery mechanisms is a challenging problem and may lead to more reliable or cost-efficient networks. In this paper different recovery strategies and interworking mechanisms are described and their functionality and performance evaluated using an integrated multilayer network simulation environment developed in the ACTS project PANEL.

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies
In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...
