“…For example, ENTRAPID [21] provides a protocol development environment, in which a "virtualized" networking kernel (including all essential networking services of a BSD Unix kernel) is implemented in the user space; protocols are implemented in the user space interacting with standard network communication services. Another notable example of node-centric emulators is NCTUns, which is built on the TUN/TAP device [45]. Network-centric emulators focus on entire network virtualization, where network transactions are "virtualized" or modeled completely in software.…”

Real-time network simulation refers to simulating computer networks in real time so that the virtual network can interact with real implementations of network protocols, network services, and distributed applications. In this paper, we present the motivation behind real-time network simulation and compare it against other major networking research tools, including analytical models, physical testbeds, simulation, and emulation. We introduce PRIME, a parallel real-time network simulator, and provide a summary of techniques that allow PRIME to model large-scale networks and interact with many real applications under the real-time constraint. We also discuss ongoing research efforts that will allow real-time network simulation to assume important roles at supporting future networking research.

“…In order to evaluate our protocol and Karthikeyan et al's MIR protocol [21], we have implemented them on the NCTUns 3.0 simulator [23]. To make a fair comparison, we modify the MIR protocol to support the same QoS bandwidth requirement.…”

“…2, was emulated using the NCTUns emulator [25] which allows the integration of simulated network topologies with real hosts running actual applications without requiring any modification of these applications. Estimations of the available bandwidth in this first scenario are performed from the hosts cronos and eolo to the host mnemosyne.…”

Modern large-scale grid computing systems for processing advanced science and engineering applications rely on geographically distributed clusters. In such highly distributed environments, estimating the available bandwidth between clusters is a key issue for efficient task scheduling. We analyze the performance of two well known available bandwidth estimation tools, pathload and abget, with the aim of using them in grid environments. Differently than previous investigations (Jain et al., http://www.caida.org/workshops/isma/0312/slides/rprasad-best.pdf; Shriram et al., in Passive and active network measurement: 6th international workshop, PAM 2005. Springer, Berlin, 2005, our experiments consider a series of relevant metrics such as accuracy of the estimation, convergence time, degree of intrusion in the grid links, and ability to handle multiple simultaneous estimations. No previous work has analyzed the use of available bandwidth tools for the derivation of efficient grid scheduling.
