Dear James Hardy,

Here below is some additional info:

What is types of network simulation tools?

Different Network Simulations

• Network Simulator version 2 (NS-2)
• Ns3.
• Netkit.
• Marionnet.
• JSIM (Java-based Simulation)
• OPNET.
• QualNet.
• The open-source simulators are Marrionet, Netkit, NS2, JSIM.

What is network simulation software?

In network simulation, a software replica of the network, or 'network model', is used to analyze how different components of the network (network devices such as routers and access points, smart phones, radios, satellites, wireless channels, etc.)

The State of Peer-to-Peer Network Simulators ANIRBAN BASU, Tokai University and University of Sussex SIMON FLEMING, JAMES STANIER, STEPHEN NAICKEN, and IAN WAKEMAN, University of Sussex VIJAY K. GURBANI, Bell Laboratories, Alcatel-Lucent and Illinois Institute of Technology Networking research often relies on simulation in order to test and evaluate new ideas. An important requirement of this process is that results must be reproducible so that other researchers can replicate, validate, and extend existing work. We look at the landscape of simulators for research in peer-to-peer (P2P) networks by conducting a survey of a combined total of over 280 papers from before and after 2007 (the year of the last survey in this area), and comment on the large quantity of research using bespoke, closedsource simulators. We propose a set of criteria that P2P simulators should meet, and poll the P2P research community for their agreement. We aim to drive the community towards performing their experiments on simulators that allow for others to validate their results.

INTRODUCTION Peer-to-peer (P2P) is a distributed computer architecture that facilitates the direct exchange of information and services between individual nodes (called peers) rather than relying on a centralized server. In P2P networks, users (i.e., human beings) participate only through their representative agents, that is, software agents running on networked devices. P2P forms the basis of many distributed computer systems, permitting each peer node to act as both a client and a server, consuming services from other available peers while providing its own service to the rest of the network. Peers within a P2P network engage in direct exchanges with their known neighbors, in order to submit requests and serve responses. The definition of what specifically constitutes a P2P system is broad. For example, in theory, a P2P system is thought of as having no centralized authority, when in reality many existing P2P applications rely on one.

Basu et al. BitTorrent1 protocol required a “tracker” in order to rendezvous the peers and perform membership management of the swarm (a swarm is a collection of peers that are interested in distributing the same content). We find that the following definition by Risson and Moors [2006] is well-suited to classifying P2P systems: Peer-to-peer systems are distributed systems consisting of interconnected nodes able to self-organize into network topologies.
