Large Scale Network Simulation Methods
Dr. Riley has been working in the field of large-scale network simulation
since his PhD thesis under the direction of Dr. Richard Fujimoto
and Dr. Mostafa Ammar. In that work he was the first to show that
distributed simulation techniques using conservative synchronization
protocols could be applied to the popular ns-2 network simulation...

1. INTRODUCTION
Predictive analysis of cyber risk and performance is one of the major gaps in cyber analytics.[1] Understanding how a specified mission-critical application will execute in a network context, characterizing the potential impact of network threats on critical applications, and predicting the effect of proposed defensive actions are critical capabilities for a risk-based...

The Mobile Network Modeling Institute (MNMI) at the Army Research Laboratory (ARL) has been established to apply High Performance Computing (HPC) tools and techniques to improve the Army’s ability to study large-scale, mobile, ad-hoc networks. Current modeling technologies offer a wide range of radio models, but fail to provide scaling and performance at an acceptable level of fidelity. Due...

We are in violent agreement with the vision and outlook of the COMBINE workshop. It is clear that effects such as feedback and rapidity of change are becoming so pronounced in global computer networks that modeling and simulation of big networks is both a timely need as well as a formidable challenge.
We are convinced that simulation is the third leg of network science, just as it has been...

Evolution of Networking Research into a Science
Introduction
Building COmputational Models for BIg NEtworks will consist of developing a complex set of models, both in the vertical and the horizontal space as defined in the call for abstracts. Among the large number of variables that must be considered, a major component is network traffic – how it has evolved over the years, what...

Many networking problems and solutions are distributed and
collaborative. To investigate them we need a realistic, detailed model
of the Internet and ideally a simulator that would work with that model
to simulate problems/solutions of interest at just the right level of
granularity. In my prior research I've worked on creating detailed models of Internet
routing, address space,...

For large-scale system simulations, two main components need to be developed; the problem model, and the simulation model. For basic sciences, the models always reflect the physical phenomena, and the challenges arise from numerically implementing those models in computational environment, and then verifying the physical phenomena. In networking, or the Internet in particular, the modeling...

The Past
In the 1990’s we got involved with Internet traffic characterization [A, D] and in particular traffic-flow profiling [B], as well as Multicast and Continuous Media Dissemination [C, J, K, L] and Wireless Internet Multimedia Communications [F, G, H]. Those investigations involved vertical understanding (for example, continuous media dissemination feasibility and contributing issues...

Abstract Purpose:
In this extended abstract, we present our broad vision of research activities that are needed to model expected and anomalous performance of end-to-end workflows in extreme-scale distributed computing applications used within the DOE communities. In addition, we present a brief summary of our current DOE-funded studies to detect and diagnose uncorrelated as well as...
