Linket Cooperation
Executive Summary
Linket Cooperation intends to redesign its network. Their current network supports email, Internet access, as well as other business applications. Lately there have been complains about downtime and slow response times when trying to accessing the network especially in the evening. Linket wishes to fix these problems by redesigning their network system. Linket management also wish to enhance productivity and improve security of the network to protect sensitive data that pass through their network.
Project Goal
The ultimate goal of this project is to redesign the network in Linket Cooperation to improve security and scalability
Other objectives of this project include:
Providing adequate bandwidth between head office and branches
Improve the overall network performance
Increase network capacity
Improve network fault tolerance
Project Scope
The proposed project is meant to serve Linket Cooperation head office and its five branches. The head office is located in New York, contain six departments to be supported by this network.
Each branch have ten departments to be supported. One department is located in Queens 10 miles away from the head office, the other one is in Hempstead 50 miles from the head office, the other is in Manhattan 100 miles from the head office, and the other one is in Newark 200 miles from the head office and the last branch is in Greenwich 500 miles from the head office.
Business Goals
Reduce operational costs:
Estimations are based on real Total Cost of Ownership (cost per equipment annually).
Current: Around $3,000,000 annually.
Expected: $5,000,272
Improve employee productivity:
This will be estimated based on the average number of employees’ hours per month:
Current: 30,000 hours per month. Expected: 25,000 hours per month.
Technical Goals
Enhance network transmission speed
Replacement of PSTN lines with T3 lines will network speed.
Enhance network security
Replacement of hubs with managed switch which provide security features that enhances security.
Creation of virtual LANs will enhance security since every department will have their VLAN.
Network Application
Internet phone
Instance messaging
Real time video conferencing
Current State of the Network
Currently Linket network suffers from occasional downtime as well as slow response time any time users try to access the network in the evening.
Network performance is affected by the number of users accessing the network.
Network connection between the head office and the branch is very weak and keeps on dropping.
Logical Design
Linket logical network topology is classified into three areas:
Enterprise Campus – This area operate independently and does not provide remote connections
Enterprise Edge – This area have function that support remote connection
Service provider Edge – provides connection to the service provider
Logical Diagram
Physical Design
At the floor of the head office, there is a mainframe and five servers. The mainframe connects to the five servers. Switches from every department connect to the mainframe.
A separate router is used for every branch.
The use CAT 5 cabling and wallplates in the office
Physical Diagram
Network Design Testing Outcomes
Network design test were successful, transmission speed improved compared to the current network.
There was improvement in connectivity between branches and the head office.
Fast response time was reported.
Reduced downtime during peak hours.
Implementation Plan
After finalizing all design details and completing design strategy, network design implementation will take place with minimal or no downtime.
Implementation plan will involve introduction of initial network test. This will be conducted on weekends to reduce interruption, however, the final test will be conducted during normal working hours in order to assess the network design performance.
Implementation Plan
During implementation, the following items will be considered:
Ensure that network design meets business objectives
Validate network technologies as well as device selection.
Ensure that the service provider offers the agreed service
Identify any connectivity issues
