About NS2 Internship Training
NS (Network Simulator) is comprise of gathering of arrangement of unmistakable event complex test systems, particularly ns-1, ns-2 and ns-3. Every one of them are discrete-occasion organize test system, primarily utilized as a part of examine and preparing. NS-2 comes completely prepared of conventions, models, calculations and frill devices. NS-2 is an open source arrange test system which is uninhibitedly accessible for scholarly research reason. In this manner, as far as logical acknowledgment, number of devices/modules and cost, NS-2 would be a kind of perfect decision.

What you'll study
At the point when the framework under research is mind boggling to either take after an investigative approach or actualize it progressively to study its conduct, reenactment is the arrangement that eventually makes it attainable by demonstrating it and nearly emulating the genuine procedure.

Section 1: SIMULATION OF COMPUTER NETWORKS
Communication programs are regularly layered. The reference show for correspondence programs, Open System Interconnection ( OSI ) is a layered arrangement of conventions in which two multilayered programs, one at either end of an interchanges trade, utilize an indistinguishable arrangement of layers. In the OSI show, each multilayer program contains seven layers, each mirroring an alternate capacity that must be performed with the goal for program-to-program correspondence to happen between PCs.
The network model is a database model conceived as a flexible way of representing objects and their relationships. Its distinguishing feature is that the schema, viewed as a graph in which object types are nodes and relationship types are arcs, is not restricted to being a hierarchy or lattice.
In correspondence and PC organize examine, arrange reproduction is a system whereby a product program models the conduct of a system either by computing the communication between the distinctive system elements (routers,s witches, hubs, get to focuses, joins and so forth.). Most test systems utilize discrete occasion reenactment - the demonstrating of frameworks in which state factors change at discrete opoints in time. The conduct of the system and the different applications and administrations it backings can then be seen in a test lab; different qualities of the earth can likewise be changed in a controlled way to evaluate how the system/conventions would act under various conditions.

Frequently Asked Questions
NS2 is an open-source simulation tool that runs on Linux. 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.
In communication and computer network research, network simulation is a technique where a program models the behavior of a network either by calculating the interaction between the different network entities (hosts/packets, etc.) using mathematical formulas, or actually capturing and playing back observations from a production network. The behavior of the network and the various applications and services it supports can then be observed in a test lab; various attributes of the environment can also be modified in a controlled manner to assess how the network would behave under different conditions.
Constant bitrate (CBR) is a term used in telecommunications, relating to the quality of service. Compare with variable bitrate. When referring to codecs, constant bit rate encoding means that the rate at which a codec's output data should be consumed is constant.
OTcl usually refers to an object oriented extension of Tcl created by David Wetherall at MIT. It is used in network simulator (NS-2) and usually run under Unix environment. This was later extended into XOTcl. OTcl may also refer to the unrelated IXI Object Tcl extension by Dean Sheenan.
A lot! Almost all variants of TCP, several forms of multicast, wired networking, several ad hoc routing protocols and propagation models (but not cellular phones), data diffusion, satellite, and other stuff. See the documentation (described above) for details, or download ns and look.
We do bug testing on the patch a couple of days before we release it with our internal team and the external playtesters. The testers are starting to organize more targeted playtests outside of our patch driven ones, though one of our goals with the beta is to have the community involved in this process as well.
