Enhancing Discrete Event Network Simulators with Analytical Network Cloud Models
نویسندگان
چکیده
Discrete event simulation of computer networks has significant scalability issues, which makes simulating large scale networks problematic. We propose to extend the approach by combining it with analytical models for network clouds, which are much more efficient, if less accurate, than nodeby-node models. Thus, simulation scenarios containing several ISP networks become feasible. We introduce a set of suitable analytical network cloud models and also describe how these models can be implemented in the ns-2 simulator using a hot-plug mechanism.

Optimal design of supply chain network under uncertainty environment using hybrid analytical and simulation modeling approach
Models that aim to optimize the design of supply chain networks have gained more interest in the supply chain literature. Mixed-integer linear programming and discrete-event simulation are widely used for such an optimization problem. We present a hybrid approach to support decisions for supply chain network design using a combination of analytical and discrete-event simulation models. The prop...

Discrete-event simulation of computer networks has significant scalability issues, which makes simulating large-scale networks problematic. We propose a high-level abstraction modeling network domains, interdomain links and traffic with highly scalable analytical models, which is much more efficient but slightly less accurate than node-by-node models. Thus, simulation scenarios containing sever...

One of the methods for analyzing systems is simulation. Network simulation is a technique that models the behavior of the network by performing transaction calculations between different network entities and using mathematical formulas and taking observations from network products. A network simulator is a piece of software or hardware that predicts the behavior of a computer network without a ...

متن کاملCost-Aware IoT Extension of DISSECT-CF
In the age of the Internet of Things (IoT), more and more sensors, actuators and smart devices get connected to the network. Application providers often combine this connectivity with novel scenarios involving cloud computing. Before implementing changes in these large-scale systems, an in-depth analysis is often required to identify governance models, bottleneck situations, costs and unexpecte...
