Executive Summary

Purpose of the Project

PH Network Service Corporation (PH) requested that CD-INC to provide a network design and implementation solution to connect four Hospitals and 120 doctor offices. PH Network Service Corporation objectives are to:
· Improve communication – transfer of the referrals
· Improve patient service
· Provide redundancy for WAN connection
· Network four hospitals and doctor offices
· Improve reliability and speed of the referrals
· Provide a suggestion for a possible back-up connection to the hospitals.

Strategic Recommendation

Timely access to information between the hospitals and the doctor offices is critical to patient care. The Network must be reliable, secure, and enable the doctors to access this system remotely from their offices with a remote access connection (RAS).

Implementation Consideration

CD-INC will design and implement entire solution. After the network is installed and functioning properly PH Network Solution will take over and provide their daily services to hospitals and doctor’s offices. CD-INC will provide training for installed equipment.

Benefits of the Solution

The solution designed by CD-INC will provide the following benefits:
· Two of their employees will be assistants in phase of developing solution (training)
· One of their employees will be involved in phase of implementation
· Training of PH staff for new installed equipment
· Improved communication – transfer of the referrals
· Improved patient service
· Redundancy for WAN connection
· Networking of the four hospitals and doctor offices
· Improved reliability and speed of the referral system
· A suggested connection for back-up hospital WAN link

Design Requirements

Existing Network

The network must be built on a limited budget.

Must be scalable for future WAN connections.

The network must work with the servers on the network.

The data must be readily available.

120 Offices transmitting data.

Table A show the Application on the Network.

Applications used by PH.

Name and Type of Application Protocols # of users # of Host/Servers Peak hours of usage

Automated referral system TCP/IP 120 1 8-12am/1-5pm

Hospital Patient Records Async - 4 8-12am/1-5pm

Patient Records from Doctor Offices Telnet - 4 8-12am/1-5pm

Network Requirements

The ISDN connections provide adequate bandwidth to support the needs of the Doctors offices connecting to the hospitals. This also means provisions must be taken to ensure more connections can be added when necessary.

An ISDN connection should also be considered for the hospital as a back-up connection to the referral system.

There are bandwidth considerations for the Windows 2000 SQL 2000 servers using a Microsoft Access front end and 2400 referrals being made each day (48000 Packets).
