Bitcoin is a swarm of cyber hornets serving the goddess of wisdom, feeding on the fire of truth, exponentially growing ever smarter, faster, and stronger behind a wall of encrypted energy

1.3 Main objectives of project

Our major objective will to make a secure system that is able to perform the following system Functionalities:

· Increase speed of processing and response time.

· Design and implementation network security and Qos.

· IP Address management &provide redundancy link to avoid link failure.

· Provide flexibility to meet user requirement.

· Upgrading existence LAN and integration of voice in network.

· Once login with valid username and password in the network the administrator can perform assignment of Address, troubleshooting and configuration.

· To perform secure login and provide remote access to the network by using telnet.

1.4 General description of the project process

1.3. 1.4.1 The statement of problem

The current network is facing the following problem;

Ø No redundancy: large failure domain, device failure, no network segmentation and link failure also synchronization

Ø Accessibility and availability: the current network is not available all the time due to failure of device and link.

Ø Security: with the current system security is not implemented to protect users.

Ø Manageability: due to local based management of network. Network administrator and technician are required to move one location to another and troubleshooting is becoming.

Ø Flat Network Design : no scalability and large point of failure

1.4.2 Proposed solution

The proposal system will ensure availability, security, redundancy, manageability and better performance of application. Where the user will be divide in terms of VLAN and all access to services will be allowed by Access Control List, also reduce link failure and device failure by implementing routing protocol and lastly to integrate voice communication in form of IP telephone in addition we have to implement 2 routers to manage traffic. Our system proposal network will allow only network administrator to login from a remote location for configuration and troubleshooting using telnet particular switches.

These are service will be provided by this network;

ü Telnet

ü IP telephone

ü VLAN(virtual local area network)

ü Port Security

ü Rapid STP( rapid spanning tree)

ü HTTP

ü Routing Protocol

ü DHCP sever and Protocol to provide IP addresses to devices on campus. There have been no DHCP outages year to date, exceeding the SLA goal of 99.95% availability.

The expect output from this project is LAN and Wireless implementation in the campus

Buildings. User may connect to the network anywhere within the campus. LAN and Wireless

Networking for small area offers computer connectivity with no strings attached.
