DESCRIPTION
Learning Computer Network Through Network Simulation ProgramTRANSCRIPT
Boson NetSim (www.boson.com) The Boson NetSim Network Simulator is
an application that simulates Cisco
Systems' networking hardware and
software and is designed to aid the user
in learning the Cisco IOS command
structure
NetSimK
NetSimK The ultimate aid to teaching and learning Cisco™ routers. NetSimK is NOT just like the other simulators on the market. NetSimK beats them hands down in all respects, including cost … a fully functional evaluation version is currently available for FREE.
You will really love NetSimK, whether you are a student or a tutor.
NetSimK was developed by a Cisco™ tutor for teaching and learning.

What is GNS3? GNS3 is an open source software (under
GPL) that simulate complex networks while
being as close as possible to the way real
networks perform.
All of this without having dedicated network
hardware such as routers and switches.
Provides an intuitive graphical user
interface to design and configure virtual
networks, it runs on traditional PC hardware
and may be used on multiple operating
systems, including Windows, Linux, and
MacOS X.
What is GNS3?
In order to provide complete and accurate simulations, GNS3 actually uses the following emulators to run the very same operating systems as in real networks:
Dynamips, the well known Cisco IOS emulator. Dynamips is a software that emulates Cisco IOS on a traditional PC. It has been created by Christophe Fillot who started his work in August 2005. The last official release of Dynamips supports Cisco 7200, 3600 series (3620, 3640 and 3660), 3700 series (3725, 3745), 2600 series (2610 to 2650XM, 2691) and 1700 series.
What is GNS3?
VirtualBox, runs desktop and server
operating systems as well as Juniper
JunOS. VirtualBox is a general-purpose full
virtualizer for x86 hardware, targeted at
server, desktop and embedded use.
Qemu, a generic open source machine
emulator, it runs Cisco ASA, PIX and IPS.
Who can use it?
GNS3 is an excellent alternative or complementary tool to real labs for network engineers, administrators and people studying for certifications such as Cisco CCNA, CCNP and CCIE as well as Juniper JNCIA, JNCIS and JNCIE. Open source networking is supported too!
It can also be used to experiment with features or to check configurations that need to be deployed later on real devices.
Who can use it?
GNS3 includes exciting features, for
instance connection of your virtual
network to real ones or packet captures
using Wireshark.
System administrators and engineers can
take advantage of GNS3 to make labs, test
network features and study for Redhat
(RHCE, RHCT) and Microsoft (MSCE,
MSCA) certifications to name a few.
Where do I start?
In most situations, to use GNS3 you first
need to provide your own copy of a
network operating system, like Cisco IOS,
PIX, ASA, IPS or Juniper JunOS.
Here is a complete list of what hardware
is emulated by GNS3
Connecting GNS3 to Real
Networks
Packet Capture
GNS3 can capture packets on virtual
Ethernet or serial interfaces. It will write
the captured output to a libpcap file that
may be viewed using WireShark.
WireShark may be downloaded
on http://www.wireshark.org.
Adding hosts to your topologies
Adding hosts to your topologies There are four possible ways to add a
computer to your topology.
If you just need to check for connectivity using ping or traceroute, the best way is to use the Virtual PC Simulator.
The second way is to use a Qemu or VirtualBox guest (Qemu and VirtualBox support are integrated into GNS3).
Third way is adding another router but configure it to act like a PC.
Finally, you may use your real PC as described in the Connecting GNS3 to real networks tutorial.
Virtual PC Simulator (VPCS)
The VPCS can simulate up to 9 PCs.
You can ping/traceroute them, or ping/traceroute the other hosts/routers from the virtual PCs when you study the Cisco routers in the Dynamips.
VPCS is not the traditional PC, it is just a program running on the Linux or Windows, and only few network commands can be used in it. But VPCS can give you a big hand when you study the Cisco devices in the Dynamips.
VPCS can replace the routers or VMware boxes which are used as PCs in the Dynamips network.
VirtualBox VirtualBox is a cross-platform
virtualization application.
It installs on your existing Intel or AMD-
based computers, whether they are
running Windows, Mac, Linux or Solaris
operating systems.
It extends the capabilities of your existing
computer so that it can run multiple
operating systems (inside multiple virtual
machines) at the same time.
Virtualization Terminology
A. Host operating system (host OS).
◦ This is the operating system of the physical
computer on which VirtualBox was installed.
◦ There are versions of VirtualBox for
Windows, Mac OS X, Linux and Solaris hosts
B. Guest operating system (guest OS). This is the operating system that is running inside the
virtual machine. Theoretically, VirtualBox can run any
x86 operating system
Virtualization Terminology
C. Virtual machine (VM). This is the special environment that VirtualBox
creates for your guest operating system while it is
running. In other words, you run your guest operating
system "in" a VM.
