Network Simulator Case Study
Network Simulator:
Network Simulator is a name for a series of discrete event network simulators, specifically ns-1, ns-2 and ns-3. All of them are discrete-event computer network simulators, primarily used in research and teaching. ns-3 is free software, publicly available under the GNU GPLv2 license for research, development, and use.
The goal of the ns-3 project is to create an open simulation environment for computer networking research that will be preferred inside the research community.
• It should be aligned with the simulation needs of modern networking research.
• It should encourage community contribution, peer review, and validation of the software.
• Since the process of creation of a network simulator that contains a sufficient …show more content…
Initially, the project aimed to find and prototype the necessary technology to prove the feasibility of an internet server that had the guaranteed availability, response time and scalability using Linux and open-source software. The project was successful, and it continued in 2001 to focus on enhancing the clustering capabilities of Linux to be the operating system of choice for the Mobile Internet servers. Many enhancements were added in the areas of load balancing, traffic distribution and security, in addition to IPv6 support.
One interesting question that came up was what is the impact of supporting IPv6 on other protocols used by different applications on our Linux clusters? To answer this question, we started a study investigating the effects of IPv6 support on other protocols, such as SCTP. Part of the study is to test applications in SCTP over IPv6. However, we did not have the time and resources to set up a lab with multiple nodes and applications that use SCTP over IPv6. Instead, we chose the next best solution, network …show more content…
It is a discreet event simulator targeted at networking research and provides substantial support for simulation of routing, multicast protocols and IP protocols, such as UDP, TCP, RTP and SRM over wired and wireless (local and satellite) networks. It has many advantages that make it a useful tool, such as support for multiple protocols and the capability of graphically detailing network traffic. Additionally, NS2 supports several algorithms in routing and queuing. LAN routing and broadcasts are part of routing algorithms. Queuing algorithms include fair queuing, deficit round-robin and
