D5.9: Extended Simulation Environment - Phosphorus

D5.6 - Extended Simulation Environment
Abstract
This deliverable presents four software tools for planning and evaluating the performance of optical Grids. Initially, a module extending the
NS-2 network simulator is presented that evaluates the performance of data consolidation algorithms (in terms of resulting job delays,
success rate, network load, etc.) for given job characteristics (arrival rates, number of datasets required per job, etc.). Differentiated
resilience for anycast services is the focus of another tool. In particular, it targets at comparing routing and server selection algorithms for
resilient networks (e.g., the effect on blocking probabilities for given job arrival and failure rates). The Optical Grid Simulator provides a
more generic simulation framework for optical Grids, allowing the definition of a variety of network and application models and providing
high modularity. Its aim is to evaluate job scheduling and routing algorithms as well as switching paradigms (OCS, OBS and burst-overcircuit
switching). Last, a network design and dimensioning tool is presented, that unlike the rest of the tools is targeted for use during the
network planning/upgrade phase, so as to create optimal designs that minimize the capacity allocated to the optical network while taking
into account optical characteristics (e.g., with impairment-aware regenerator placement).
