ns-3 is written in C++ and compiled into a set of shared libraries that are linked by executable programs that describe the desired simulation topology and configuration. Python bindings are optionally provided using cppyy, allowing users to write simulation programs in Python. The ns-3 simulator features an integrated attribute-based system to ...
In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc. [1] Most simulators use discrete event simulation in which the modeling of systems in which state variables ...
OTcl usually refers to an object oriented extension of Tcl created by David Wetherall at MIT (hence the name OTcl—short for MIT Object Tcl). [1] It is used in network simulator (NS-2) and usually run under Unix environment. [2]
The first implementation of TCP Westwood in ns2 was done at University of California, Los Angeles (UCLA) in 1999. The name "Westwood" was chosen by S. Mascolo as due homage to the home of UCLA where he was a visiting researcher at that time. Main collaborators were prof. Mario Gerla, Dr. Claudio Casetti and Dr. Medy Senadidi.
OpenNIC (also referred to as the OpenNIC Project) is a user-owned and -controlled [1] [2] top-level Network Information Center that offers a non-national alternative to traditional top-level domain (TLD) registries such as ICANN. [2]
A "Hello, World!"program is usually a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
