Bead Bar Network Design

19th August 2007

Introduction

Bead bar is a company which specializes in making beads jewellery for the customers . They have three divisions ' namely studios , franchises and bead bar on board

It is required to create a network design and the appropriate topology which would be of good to the company for communicating the requirements and sharing information to keep in synchronization with the current state of the business

The network topology would be discussed which would make the

communication feasible and possible with regard to all the physical and network barriers

The network design is the architecture which would give a clear picture of the interconnection of devices and the departments to facilitate the sharing of business information

The final section would discuss the pros and cons of the proposed topology in question

Network topology

The very organization of the company into departments and their location are the prime factors for designing the network topology and the technologies to be used for efficient communication and sharing of information

Explanation of the Network Design

All the three divisions of the company are interconnected using the network cable in a wired network using both LAN and WAN

Using LAN the computers are interconnected within the office or building premises so that all the employees are able to get information on demand . The head office has a central server where all the information us stored in the database . The other offices are also networked using the LAN technologies . The switch is two layered and used to take care of the storing and forwarding mechanism

Using WAN the network connections are using the public data services and get connect to internet and using VPN technology , using login credentials

Network Topology

The LAN technology follows a star topology with hubs . The interconnecting devices used facilitate the use and share of information . The hubs are used to store and forward the information

Star topology is used which would facilitate the efficient use of network resources

Advantages of the architecture

Having a star topology would make it less expensive in relation to mesh topology

In a star , each device needs only one link and one I /O port to connect it to any number of other devices (Forouzan , 2003

It makes the star topology easy to install and reconfigure with time and need

Star topology requires far less cabling and any additions , deletions and moves involve only one connection between that device and hub

It is quite robust in nature if one link fails the others do not cease to operate . This factor also enhances the fault identification and fault isolation

As long as the hub is in working condition , it is quite easy to monitor link problems and bypass defective links

A WAN is used for connecting to the internet so as to get connected with the other departments across geographic locations

VPN technology is used to validate the user of the network so that the connection established is secure in nature . It would use the login name and password facilities to enable a secure way of handling data

A database server is used so that all the information is stored centrally and all the users access the information using their credentials

The VPN also makes sure that not all users would be able to access all for ms of data an data security and integrity is restricted using the login credentials

Drawbacks of the architecture

The VPN technology would be quite expensive to implement

The cost of switches and hubs would be costly

The use of websites where all the computers are used for accessing directly the internet would have made the architecture more accessible but security would have been less . Even the cost of web server would be incurred quite high

Conclusion

The proposed network architecture would make the Bead Bar meet all its networking requirements so that every department would be able to communicate with another so as to share knowledge and business requirements . The customers can be better managed and serviced well
