world of general merchandise including home furnishings, utensils, crockery, cutlery, sports

goods and much more. And this is just the beginning. Net Bazaar plans to add much more to

complete your shopping experience.



Chapter 1 Client’s business analysis



Client’s business scope

Net Bazaar is one of the prominent business retailers in India with their supply chain

management extended all over India. So their business scopes from Medium - Large scale.

Client’s Geographic location

Net Bazaar public Ltd base location is in Bangalore, India and they have 8 remote offices all

over India. All of this remote location have retail concept along with local sales offices.

Business Threats

As Net Bazaar is a supplier chain management company and in a country like India retail market

segment faces a huge competition.

- Retail business runs mostly on strategies. Any espionage may lead Net Bazaar out of

business.

- Online transactions are the core elements of retail and supply chain management.

And online transactions historical proved are most vulnerable target of cyber

crimes.



Client Requirements

- Secured network[No scope for espionage , no security breach]

- Keep business updated [ Updated about current market scenarios]

- Supply chain management needs a strong inventory management i.e. updating stock and

sales reports from remote retail stores.

- Stay connected with all the business aspects (Retailing, accounts…)

- Enhance the hardware of the organization

Assumptions

- As there is no specific floor plan provided in the project specification, our team is taking

up Vertical view of the building network design rather than longitudinal one which is

more floor plan specific. Our assignment is less on cabling & arrangement but more on

protocols, standards and hardware.

- Our team is free to make realistic assumptions where ever the information from client is

limited to build a network

Backup Links:

LAN backup


This scenario shows that same two LAN links.

In this scenario Main link on the right is down so without any manual intervention Back up link gets activated

Image above consists two LAN lines

- Main Link

Right link the main link which is active

- Backup line

Left one is back up link and is in active as the main link is active


WAN backup


Above scenario enumerates WAN BACKUP

Two backup links:

- Frame Relay

Frame relay is the primary WAN connection.

- DSL

DSL is used as back up link that can be activated automatically when primary link is down or when the traffic load is heavy.

Chapter 3LAN & WAN Standards

Net bazaar Network Design

1. VLAN(IEEE 802.1Q)

Main LAN is divided into 3 VLAN’S:

- Accounts



- Admin

- Default/ All Users

The Network Configuration in main office 3rd floor that depicts that whole network is

divided into 3 VLAN’s one for General/ Default users, one for Administration & one for

Accounts department.

2. Standard Ethernet(IEEE 802.3)



Standard Ethernet is used in the back up lines of the whole network, whenever a line is

down before it is corrected back up lines that run on standard Ethernet will be triggered

and they can operate up to 100 MBPS

3. Fast Ethernet (IEEE 802.3u)

All the main lines in the network are built upon the Fast Ethernet and they can work up to

100 KBPS

4. Wireless LAN(IEEE 802.11g)


The adjoining figure shows the Back up and the Main lines.

Back up lines are the one with orange display and the one with green display are Main lines

In this network setup Back up lines work with Fast Ethernet and Back Up lines work with Standard Ethernet


Fig 1.2 shows the ground floor in remote LAN that is built on WLAN standards with

Linksys devices

5. Frame Relay

Frame Relay is a WAN standard that is most famous from 80’s. In this design Frame relay is the

WAN design that we selected for connecting the remote offices. A leased line with a global IP

address will be got on a lease from BSNL.. Frame relay can work at very great speed and gives a

greater security as it is on a leased line.

- Leased lines

- Amazingly fast

- Security is high

- Can with stand greater data over load.25 | P a g e



6. DSL

DSL as used as backup line for WAN it will be activated when:

Traffic exceeds main link load capacity

Whenever main line is down backup acts as WAN link

7. Virtual Private Network

Even though VPN is not a full WAN standard it will be useful for the organizations in

many ways. Recently from many years VPN is becoming the de facto standard for the

organizations to connect to remote offices In contrast to the Frame Relay it is cheap and



is too fast but the down side of the VPN is that it can’t operate when it has heavy duty

data transfer.

- In VPN no leased line is needed; it just work on the internet

- Setup costs are strikingly low

- Amazing performance

- Relatively less security

8. Enhanced Interior Gateway Routing Protocol

- EIGRP is the most widely used routing protocol

- It is not proprietary like OSPF by Cisco

- Network convergence is too fast



- Considered as the state of art routing protocol

EIGRP Packets all through the network in simulated network of Net Bazaar

9. Net bazaar Intranet

As part of the network design we have developed an Intranet and extranet for the Net bazaar.



- Main server is located in 2nd floor of HQ

- Routed through EIGRP

- HTTPS & HTTP support provided

Fig shows Sample web page from Net bazaar’s simulated Intranet on Packet Tracer

10. Net Bazaar Network – Security Measures



AAA Servers

Net bazaar network is provided with AAA servers that can Authenticate Authorize Account the

users on the network

AAA has two protocols:

- TACACS+

- RADIUS

Radius server is proposed at the main office of Net bazaar that helps the network admin to

authenticate and authorize the user effectively

Wireless Encryption Protocol(WEP)



WEP is the encryption protocol that is to be used on the wireless routers of net bazaar to

protect it from unauthorized access/ intruders.

11. Net Bazaar – Servers


Wireless router prompting the client for the encrypted WEP key.

Adjacent figure shows two clients:

- One client has been declined due to lack of credentials

- Other host connection accepted by authenticating using WEP


HTTP

Hosts the Intra & Extranet of the Net bazaar. And can be accessed from any company

hosts on the IP 192.168.1.250

DNS

192.168.1.200

DNS has all the domain-IP mappings regarding the Intra & Extranet of the Net bazaar

network



DHCP

DHCP is used to assign IP’s dynamically for every PC in the Network that reduces the

tedious jobs for network admin’s



AAA server

192.168.1.149

AAA is the key to the whole network Authorization Authentication and accounting

Database Server

Database servers are used to back up all the data of the organization. Under any abnormal

situation or damage to data this server plays major role in disaster recovery.

CAT 5 E Cable

Category 5 cable is a twisted pair high signal integrity cable type often referred to as Cat5 or Cat-5. Most cables are unshielded, relying on the twisted pair design for noise rejection, and some are shielded. Category 5 has been superseded by the Category 5e specification structured cabling for computer networks such as Ethernet, and is also used to carry many other signals such as basic voice services, token ring, and ATM (at up to 155 Mbits, over short distances).

Chapter 5Conclusion & Limitations



Conclusion

The network design by our consultancy for Net Bazaar consists of robust WAN technologies and

backup plans and every at most care is taken regarding security measure like WEP for WI-FI

security AAA servers for authentication ,authorization and accounting Of network resources

With all the measures taken in designing the above network can be concluded as:

Robust: with a strong back plan

Scalable: as hardware is proposed keeping the growing business in mind

Secure: as the entire network resources are protected,

Available: with a good back up and disaster recovery network and data will be available any

time even under any chaos.

Limitations

We confined the project scope till network layer and a very little on physical layer (cabling…).

So, this assignment can’t guide anyone who is concerned with physical level design of networks.
