Communication protocols are the force by which network devices can communicate with one another. The main protocols used by applications are TCP, UDP, IP protocols, ICMP, IGMP, SCTP and DCCP, ARP, and routing protocols. Each protocol serves its own unique purpose, for example HTTP uses TCP port 80. TCP or Transmission Control Protocol uses a handshake method to make sure that data makes it to a location in full, and in the correct order. This is important for data such as Web pages, because if the data was corrupted it would be impossible for the end user to read. UDP or User Datagram Protocol is just the opposite of TCP. It sends information without regard for the end state of the data. This protocol generally carries data in which packet loss is acceptable, for instance SNMP uses UDP. SNMP is strictly for monitoring purposes, and is not mission critical to applications. These are just a couple examples of communication protocols, but it is already obvious that without them there would be no network communication.
Riordan Manufacturing has several protocols that they will use to communicate between their users and servers. They also have several protocols that they will use for routing. First, all devices on the network are subject to ARP (Address Resolution Protocol). This protocol is used on layer 3 devices such as routers and layer 3 switches. ARP correlates a devices MAC address (Layer 2) with the IP address (Layer 3). This allows a router or switch to be able to locate a device on the network, and more efficiently route traffic. The routers will also use routing protocols between the ISP (Internet Service Provider), and/or the neighboring data centers. They would most likely use BGP to their ISP, and iBGP to the neighborin...

...nnectivity for all MAC Pro’s with the lack of switchports, and also provide additional convenience for users. The 1Gb connection between datacenters will allow layer 2 connectivity so that all applications and phone systems can be used at the legacy facility until everything has been decommissioned.

This solution operates without requiring the company to buy duplicates of all the servers and printers. This saves the company money, and valuable time that would be spent configuring the additional devices. Sometimes network design solutions can be accomplished in many different ways, and it is the needs of the business that can determine the direction in which the design takes.

Employee motivation and rewards are effective means to retain employees. When an employee is motivated, his or her needs are being met. When an employee is unmotivated, his or her needs are not being met which results in a high employee attrition rate. Riordan Manufacturing is experiencing a high attrition rate. Riordan Manufacturing has 3 plants and employs 550 people. Recently, Riordan hired Human Capital Consulting to perform an analysis on the underlying issues that are causing the decreasing employee satisfaction and to recommend courses of action that will address the underlying issues. Research has been done to identify the issues and opportunities, the stakeholders and ethical dilemmas, and the end state vision. A gap analysis has also been performed to determine the gap between the current situation and the end state goals. Riordan Manufacturing will use this information to determine the best way to proceed towards improving its working environment for the employees.
In the past, college graduates would embark on careers in the business world with book learned business theory. Now the college curriculum can include practical use of real world situations in a web-paged virtual organization. This virtual organization allows students experience to review, analyze, troubleshoot and resolve real business problems. This paper will review the virtual company, Riordan Manufacturing, allowing students to review existing business systems, identify improvements or introduce new business systems to allow the company to thrive in the growing technology of the business world.
Although Riordan Manufacturing has a generic strategic direction, a comprehensive strategic plan reevaluation and development must occur after the move to China. Environmental scanning, strategy formulation, strategy implementation, evaluation, and control are fundamental to the creation of a strategic plan (Wheelen & Hunger, 2010). Because, strategic planning is integral to the corporate strategy and success of Riordan the board of directors' requesting Team B formulate a comprehensive strategic plan for their organization.
The networks are split into two groups. There is a Production network and a Development network. Each of these networks resides on their own separate sub network. The reason for splitting the networks into two is to prevent network overload and slowdowns that would otherwise affect other departments within MKS such as Customer Service or Accounting. The production network involves non-development tasks such as the customer service database, email, the order entry and accounting systems. The development network involves all areas relating to product development. This network covers the server that stores base code, the development system, development tools, software libraries and software builds.
Meanwhile, the advent of early PC’s and the recognition of the value in networking devices together gave rise to Local Area Networks. These LAN’s were developed from a business customer perspective, which placed more emphasis on costs and ease of use over reliability. There were a number of different competing LAN technologies, two of the most common being Token Ring (IBM) and Ethernet (everyone else). The triumph of Ethernet in the marketplace, to the extent where it is included in every PC, game console and some refrigerators, provides a consistent and relatively inexpensive way to build internal networks with relative ease.
The Open Systems Interconnection (OSI) reference model has significantly influenced the development of internet protocol we use today. Created in the 1980’s by the International Standards Organization (ISO), a multinational body dedicated to worldwide agreement on international standards, this reference model has defined the entire network communication process into seven structured layers. In ascending order these layers are the physical, data link, network, transport, session, presentation, and application layers. The purpose of this model was, and still is, to simplify and set a standard for the design of communication and networking products that can communicate with each other, regardless of system differences.
In order to have a greater understanding of the terminology and descriptions offered in this paper, we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network segments. It uses the logic of a Network bridge, but allows a physical and logical star topology. It is often used to replace network hubs. A switch is also often referred to as an intelligent hub.
Switches, which are layer 2 devices, use decision based routing by storing NIC hardware addresses and port numbers on a table in the switch. By doing this, when data is received by the switch, it knows where the source was, and where the data needs to go. This allows for faster data transmission for all NICS that are connected, because it uses the swi...

Virtual Private Network presents some advantages over the traditional network technologies. VPN offers direct cost savings over leased lines or long-distance calls for remote access, savings resulting from reduced training requirements and equipment, increased flexibility, scalability, and security. The main advantage of VPN is the cost savings of Internet VPN when compared to networks built using conventional leased lines. Leased lines include tariffs that have an installation fee, a fixed monthly cost, and a mileage charge. The cost to an organization of traditional leased lines may be reasonable at first but can increase exponentially as the organization grows. As an organization grows and more companies must be added to the network, the number of leased lines required increases dramatically. VPN that utilizes the Internet avoids this problem by simply tapping into the geographically distributed access already available. Another way VPN reduces costs is by reducing the need for long-distance telephone charges for remote access. Instead of having the offsite team of a company dial into the corporate modem bank via long distance lines, the company’s VPN allows them to simply place local calls to the ISP’s POP in order to connect to the corporate network.

Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
In addressing the problem, the proposed research will use the case study method to examine the plan, design, and implementation of WLAN technologies at Berean. At present, the non-wireless local area network (LAN) technologies employed by Berean include 10/100BaseT Ethernet at each desktop. Ethernet ports at the desktop are switch connected to an Asynchronous Transfer Mode (ATM) T1 backbone. Berean¡¦s one remote facility connects to the network using switched Frame Relay services along with Internet Virtual Private Network (VPN) connections.
