Advances in network simulation

L. Breslau, D. Estrin, K. Fall, S. Floyd, J. Heidemann, A. Helmy, P. Huang, S. McCanne, K. Varadhan, Ya Xu, Haobo Yu
2000 Computer  
Researchers study networking protocols at many levels, ranging from the detail of an individual protocol to the aggregation of multiple data flows and the interaction of multiple protocols.  ...  Moreover, the model can embed macro-objects in other macroobjects, leading to a hierarchical architecture that supports multiple levels of abstraction.  ...

Towards predictable datacenter networks

Hitesh Ballani, Paolo Costa, Thomas Karagiannis, Ant Rowstron
2011 Proceedings of the ACM SIGCOMM 2011 conference on SIGCOMM - SIGCOMM '11  
As a matter of fact, Amazon's ClusterCompute [2] addresses this very concern by giving tenants, at a high cost, a dedicated 10 Gbps network with no oversubscription.  ...  exacerbated by the oversubscribed nature of datacenter network topologies [14] .  ...  Such topologies are hierarchical and are recursively made of sub-trees at each level.  ...

2012 Computer communication review  
This allows researchers and operators to explore new protocols, create complex models of networks and predict consequences of configuration changes.  ...  However, our abstractions could also allow the discussion of the broader configuration management problem.  ...  We allow the user to specify the network topology at a high-level, in a standard graph exchange format.  ...

An automated system for emulated network experimentation

Simon Knight, Hung Nguyen, Olaf Maennel, Iain Phillips, Nickolas Falkner, Randy Bush, Matthew Roughan
2013 Proceedings of the ninth ACM conference on Emerging networking experiments and technologies - CoNEXT '13  
Emulated networks and systems, where router and server software are run in virtual environments, allow network operators and researchers to perform experiments at large scale more economically than in  ...  However, large scale comes with a problem: running real software means each test needs at least as much configuration as a real network.  ...  We would like to thank the suggestions, discussions, and coding contributions from Niklas Semmler, Askar Jaboldinov, Benjamin Hesmans, Olivier Tilmans; and members of the VIRL team at Cisco: Joel Obstfeld  ...

Scheduling distributed applications: the SimGrid simulation framework

A. Legrand, L. Marchal, H. Casanova
2003 CCGrid 2003. 3rd IEEE/ACM International Symposium on Cluster Computing and the Grid, 2003. Proceedings.  
This paper focuses on SimGrid v2, which greatly improves on the first version of the software with more realistic network models and topologies.  ...  One possibility is to conducts large numbers of back-to-back experiments on real platforms. While this is possible on tightly-coupled platforms, it is infeasible on modern distributed platforms (i.e.  ...  The default resource models in SimGrid as described in Section IV-A do not enable realistic simulation of network traffic on topologies in which paths between hosts use multiple network links.  ...

Meridian: an SDN platform for cloud network services

Mohammad Banikazemi, David Olshefski, Anees Shaikh, John Tracey, Guohui Wang
2013 IEEE Communications Magazine  
The Meridian cloud networking platform architecture design is inspired by the emerging conceptual models of softwaredefined networking.  ...  It is organized as three main logical layers: network model and APIs, network orchestration, and interfaces to underlying network devices.  ...  ABSTRACT API LAYER The goal of the abstract API layer is to present applications with a network model and associated APIs that expose only the information needed to interact with the network.  ...

Cristian Grecu, Andre Ivanov, Resve Saleh, Claudia Rusu, Lorena Anghel, Partha P. Pande, Vasile Nuca
2008 2008 1st Microsystems and Nanoelectronics Research Conference  
We have designed a simulation environment that allows early exploration of the performance and cost parameters of network-on-chip communication architectures, which is able to handle arbitrary topologies  ...  The simulator implements a flit-level message-passing mechanism and supports application data specified as input trace files or generated at run-time by synthetic traffic generators.  ...  [9] , with data processed at transaction level by a network engine that can implement high-level behaviour of point-to-point, bus-based, and crossbar interconnects.

Dynamics of Relative Agreement in Multiple Social Contexts [chapter]

Davide Nunes, Luis Antunes, Frederic Amblard
2013 Lecture Notes in Computer Science  
We discuss the influence of complex social network topologies where actors interact in multiple relations simultaneously.  ...  We present an agent-based model that defines social relations as multiple concomitant social networks and apply our model to an opinion dynamics model with bounded confidence.  ...  The model here presented, while abstract by nature, can unveil interesting dynamics that should be taken into account when modelling complex social spaces for simulation models.  ...

2015 Proceedings of the 1st ACM SIGCOMM Symposium on Software Defined Networking Research - SOSR '15  
We present Slick, a framework for programming network functions that allows a programmer to write a single high-level control program that specifies custom packet processing on precise subsets of traffic  ...  In contrast to previous work, Slick handles both the placement of fine-grained elements and the steering of traffic through specific sequences of element instances, allowing for more efficient use of network  ...  Acknowledgments We thank Jennifer Rexford for her thoughtful comments throughput the course of this project. This work was supported by DARPA through the U.S.  ...
