NETWORK IMPLEMENTATION PLAN 3

Abstract
During the duration of this class my focus will be developing options to provide the company with a new network infrastructure. A company called Medical Needs have requested that I create the network infrasture for the two locations in Tennessee. They have hopes to expand to other states in the Southeast. Medical Needs provides orthopedic devices and replacement parts for crutches, braces, wheel chairs and any other medical aids that may be needed. The goal will be to develop the appropriate network design for this company with the ability to expand and grow in the future and cost effective. In order to accomplish this goal, I will have to ensure all the equipment in these two offices can support the network infrastructure needed to accomplish the desires of the company.

Target Organization

Description of Company
Medical Needs is a company providing medical devices to people as prescribed by their doctor, this could be anything from, crutches, braces, cpaps and many other medical needs. The offices are presently located in Nashville and Chattanooga with plans to expand to other areas of Tennessee in the future. The two companies are both rather small currently, with approximately ten employees in each location. With the right network choices, they could continue to grow and compete with the other medical device companies in each area.

We will make controlling the inventory of both companies more efficient. Prescribing devices will be streamlined to make it effortless for physicians, along with the customers receiving the product needed without any wait time, by ensuring the device is available immediately. The key to these goals will depend on the network structure implemented with reliability, maintenance free, and secure to protect confidential patient information.

Proposed Network Solution
Network Solution
When designing a network, four major considerations should be considered. First, the network must have an uptime of 99 percent. Second, the network for the organization must meet HIPAA compliance. Third, the network must be easy to use, troubleshoot, and manipulate. All the organization policies ought to govern the network to keep it productive, secure, and efficient.

By keeping these considerations in place, a medical device facility can better facilitate its employees and patients to have a smooth working environment. The report will highlight how installation and configuration of physical hardware will be done. Lastly, the paper will highlight how remote access and maintenance will be done together with the required network pro prep toolkit.

Network analysis
To meet the network design goals for any organization it is very important to first figure out the possible critical points of failure. For a medical facility such as this one the critical points of failure are hubs and switches which links the doctor’s office, billing offices, hospital labs, and operating rooms. Another point of failure is the location of servers or the data center which contains critical data and patient records. Other points of failure including cabling, hard-disks, NICs, internet gateway, PSTN link to the ISP, and the VPN connection to the remote offices (CiscoNetworkingAcademy, 2014).

The following illustrates the proposed hardware for Medical Needs company. To start with, the company data center ought to be located at Nashville. This acts as the brain of the company as it dictates data and information flow. This means that the company needs to use a line of top high-end servers. In addition, the company need to employ the use of server virtualization where two virtual machines will be used i.e. RedHat Linux Enterprise version six and windows server 2012 for communication, imaging and Computerized Practitioner Order Entry system (CPOE).

The specifications of the servers are highlighted by below:

Processor

Intel Xeon dual core with a minimum of 3.16 Ghz

Expansion slots

2 PCI-Express

Network interface

Dual Gigabit Ethernet

More detail of the Proposed Network solution will be explained in the Network Design content to be submitted next week.

Network Design
This section demonstrates the physical topology of the company network. The main office is in Nashville and the remote office located in Chattanooga as shown by figure 1 below

The proposed physical design has four major features. First, the cabling is done using CAT 6. Second, manageable switches have been used to connect to various offices. The manageable switches help in managing and controlling LAN which offers a better control of information and data transfer. Also, the manageable switches used the SNMP protocol for the monitoring of devices on the organization network Lastly, a firewall, which is utilized to deny access to unauthorized users (Lammle & Swartz, 2013).

To meet the company requirements, the relevant logical design is Cisco SAFE architecture. This is because the main objective of this design is to provide the very best practice for implementing a secure network. In addition, this design implements a modular approach which allows flexibility in troubleshooting. A Cisco SAFE architecture takes what one would refer to as a defense-in-depth approach where various or multiple layers are strategically located throughout the organization network (Kurose & Ross, 2009).

Ensuring that the appropriate connections and security are in place are crucial to the success of the organization. Each of the locations should be able to share information that is stored centrally. The network configuration will be one that consist of a central location where the primary file servers will reside. In addition, the remote locations will be connected via the Internet and a VPN to ensure that the communication between them is secure as it travels over the Internet. DNS will provide the primary components for the organization to access internal servers as well as external routing to servers on the Internet. DHCP is a preferred protocol since it is highly flexible in assigning IP addresses based on the available ranges in the routers to which devices are connected.: (Hughes, 2016) Network protocols will be the typical used in many organizations focused around TCP/IP.

There is no need to utilize additional protocols that may be restricted based on IP etc. IP Routing will serve as the backbone of routing both internal and external with switches serving the machines in the office and a router to direct traffic to external IP addresses. Certificates will be utilized as necessary to ensure that the machines that are communicating with each other belong to the appropriate approved parties. SSL based certificates will be standard for all bank interoperability: (Hughes, 2016). While WINS will be considered I don’t believe it will be necessary given the TCP/IP routing in place using the DNS servers.

The logical design for Medical Needs company ought to be divided into three functional areas which are enterprise campus, service provider, and enterprise edge. The proposed logical design is as shown by figure 2 below
