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 Ė 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.
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).
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 doctorís 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 Ė 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
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
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).

What words come to mind when you think of ContinenWhat words come to mind when you think of Continental Airlines? Successful company, preferred airline, good service, on-time airline, top carrier, financially solvent, happy employees. These are all true; however, this was not always the case. Just six short years ago, probably not one of those descriptions would even be said in the same breath as Continental Airlines. In fact, in 1994, Continental was facing its third bankruptcy; that bankruptcy would have been the final blow to take this airli
I. History of Intel Corporation [Back to Top]I. History of Intel Corporation [Back to Top] Robert Noyce and Gordon Moore, who had left Fairchild Semiconductor, founded Intel Corporation in 1968. The current chairman of Intel, Andy Grove, had also come from Fairchild to become Intel\'s 4th employee. Their first commercial product was the 3101 Schottky bipolar 64-bit static random access memory (SRAM) chip, and it was moderately successful. The success of Intel didn\'t come until the early 1970\'s. Intel was a company founded on the risk/rew
How to Go From Class-Room to Web-Room as PainlesslHow to Go From Class-Room to Web-Room as Painlessly as Possible By Rik Hall, University of New Brunswick, Fredericton, New Brunswick 1.0 ABSTRACT Getting your course onto the World Wide Web (WWW) is best done using a systematic approach. There are a number of steps that need to be taken prior to starting any of the actual web work. Meetings should be held with various groups within your institution. Once the actual coursework is begun, there are some essential components and some optional compon
INTRODUCTION OF NETWORKINGINTRODUCTION OF NETWORKING One problem that I see with people today is that they are unaware what a computer network is. They might have heard of a computer network, but they are clueless as to how it works or why it works. People have basic questions that need to be answered. My goal is to give basic network information that will hopefully answer those questions. To give people an understanding about computer networks there are several areas that I must focus on. I will give definitions of some

In the perpetual darkness more than two miles below the surface of the North Atlantic, a submersible sled slowly traced the alpine contours of the ocean bottom in the summer of 1985. Named the Argo after the ship in which the legendary Greek Hero Jason sought the Golden Fleece, the 16-foot-long craft resembled a section of scaffolding flung on its side and stuffed with equipment, Powerful lights, sonar, Video cameras.

The CIS professors would be using the server for various operations. Assignments, e-mail, and other types of information would be easier for the students to access. Network users are able to share files, printers and other resources; send electronic messages and run programs on other computers. However, certain important issues need to be addres
E-commerce an IntroductionE-commerce an Introduction In the broadest sense, electronic commerce (e-commerce), is the buying and selling of products and services over the Internet. It has included the handling of purchase transactions and funds transfers over computer networks. According to the Forrester Research Study Sizing Intercompany Commerce, total U.S business-to-business Internet trade in 1998 is $7.7 billion, compared to a total global e-commerce of $21.8 billion, dramatically increasing from $2.5 billion in 1997
Principle Economic IndicatorsPrinciple Economic Indicators The million (or should we say \'billion\' now) dollar question is whether or not the United States\' economy will stay in it\'s record 107 month expansion (according to the index of leading indicators) or come out of the boom and take a downturn into a recession. Nobody, including the Chairman of the Federal Reserve, Alan Greenspan has a crystal ball to provide insight as to what will happen if interest rates are raised, lowered, or left alone. However, Economists h

Are There Tests That Could Predict Violence in SchAre There Tests That Could Predict Violence in School Students? This is an overview of the types of constructs which one might look at to determine if a student is in a high risk category for acting out in a violent manner, and the types of tests which would measure those constructs. We will look at some of these predictors, the constructs they attempt to measure, and how this might aid in predicting future behavior. There have been a lot of studies, interventions, programs, and models designed
Artificial IntelligenceArtificial Intelligence Artificial Intelligence once something that people thought could only come out of science fiction novels and movies. But today that could all change because of a robot called Cog. Cog is an artificial intelligence that itís creators have given a body. He is the future of AI and a new beginning for the field. His creator , Rogney Brooks, a professor of electrical engineering and computer science, thought of creating cog, from inspiration from an artificial intelligence tha

Perhaps one of the most complex pieces to the humaPerhaps one of the most complex pieces to the human puzzle is our sense of humor. A sense of humor not only involves intelligence and comprehension but also an array of emotions. It is not enough to just understand something humorous, but it is also necessary that an emotional and physiological response be able to occur for a person to have a sense of humor. However, though there is much involved in getting a joke, there are even more factors involved in telling a joke(Ziv 27). This is, unfo
