Abstract:We present a case study on thearchitecture of network distribution in our

campus through LANs, Wi-fi and VoIP

connections. We present how the proxy server isset up to distribute the internet coming from ISP

to the various users through intermediate

switches and routers. Owing to the bottleneck

created because of the constraints in the transfer

capacity of normal cables as opposed to the

connecting optical fibre cables, the network performance tends to get degraded. We suggest

alternative configurations by which the problem

can be countered.

2. Mobility.The former can be realised with optical fibresand the latter with various wireless links.

Following these trends, our case study aims tosuggest measures to counter the growing

network needs at National Institute of

Technology, Hamirpur.

II. Architecture

Firstly, the central inter-network line comes

from the Internet Service Provider (ISP) to therouter, which routes the incoming signals to the

core-switch, which is presently located in the old

the past few months is Address ResolutionProtocol (ARP) spoofing or ARP Poisoning.

This can be simply understood by the following

example:

Suppose we make an entry in /etc/hosts on a

Linux machine saying that google.com resolvesto 127.0.0.1, now whenever we will try to visit

google.com, we'll eventually end up at localhost.

Similar concept is followed for ARP Poisoning.

The attacker sends malicious packets which

force the domain names to be resolved in such away that all requests eventually end up on his

machine. The clients feel that the internetservice is not working, whereas the attacker is

not letting it work. The scenario becomes further

adverse when the attacker spoofs his identity

while attacking.

V. Statistics

From the statistics, it can be inferred that therehas been almost no usage between 25th

and 29th

January, 2010.Also, it shows that during thedays when people were facing internet problems,

bandwidth was being used. This clearly proves

that ARP and related attacks are being

attempted.

Conclusion:

To enhance the speed and reliability, the transmission should be

done using optical fibre cables.

The following counter measures can be adopted for preventingattacks on the network and for ensuring optimal usage:

MAC to IP binding

Delay Pool Implementation (Bucket System)

Authenticated Access (Quota System)
