Short Description

The aim of th
is Lab

is to emulate several Metropolitan Area Networks (MANs) at the
nationwide scale so as to let students learn how the Internet operates and scales up.

In this lab, students will:



study Internet routing architectures an
d various dynamic routing protocols
such as RIP, OSPF, IGRP & EIGRP, and BGP4.



set up and manage some virtual Internet eXchanges (IX), national Network
Service Providers (NSP), and Enterprise Networks so that they can understand
the roles of these parties

in the Internet, and know how these parties operate
and interact with each other.



have hands
-
on experience in setting up and operating network equipment and
Internet servers (such as switches, routers, and firewalls) in virtual IX, NSP
and Enterprise Net
work environments.





Detail Description

Objectives



Let students have
hands
-
on experiences on setting up and managing IXs ,
NSPs and E
nterprise

N
etworks



Let students learn how the Internet, NSP and enterprise networks operate and
how they can be scaled

up



Let students understand the parties involved in an IX , NSP and enterprise
networks



what are their roles in an IX, NSP and enterprise networks



how do they co
-
operate in an IX ,NSP and enterprise networks



try to have hands
-
on experiences of acting t
hese roles in an IX ,NSP and
enterprise networks



Let students understand the Internet routing architectures and most

dynamic
routing protocols, such as

RIP, OSPF, IGRP & EIGRP, BGP4 ... etc



Let students have hands
-
on experiences of setting up and managi
ng network
equipment in an IX and NSP environments, say routers and switches.


Setting

National NSP Setting



Regional providers are connected to national providers at POP (Point Of
Presence)



POP are interconnected to form a National NSP (Network Service P
rovider)



POPs of different National NSP
are connected to a regional IX



Enterprise networks are connected to NSP across different geographical
regions.

A regional IX connects several NSP in its IX LAN

Enterprise Network

Nodes in the Enterprise Network are connected through Internet or internal private
network.

Capacity

Four NSPs and four IXs is the minimum setting so as to generate enough traffic and
interaction among the NSPs and IXs.

With this setting, we can provide



36 different tasks ( 4 IX + 16 POP + 16 enterp
rise networks setup and
operation)



20 Cisco routers



8 switches



160 virtual hosts
