Existing network analysis in an important step when designing a new network as it establishes relevant information about the current network infrastructure and its bottlenecks. It is also a tool that helps to establish the needs and requirements of the company. Requirements of the networks in terms of the application and services are what drive the design of the network. This chapter reports on the outcome of the network analysis, giving details on the existing network design, hardware, protocols and identified bottlenecks in the design and finally offer recommendations that will be the basis of the new design. 4.1 OVERVIEW OF THE EXISTING NETWORK The existing network design is flat network that has evolved over period of time to meet the …show more content…
There is no network documentation which makes troubleshooting and understanding the network very difficult, to a new person. The company consists of single building; divided into two floors, the main section is separated to the other back office by workshop area. This back office is connected to the main office switches with a single shielded cat5e cable, the distance exceed 100 meters a 4 port netgear switch was acting as a bridge between the two sections. The company is located in an area where the easy available internet connection is via ADSL line with a maximum speed of 3.5Mbps, therefore to get sufficient bandwidth and have backup internet connections, three 3 different internet service providers (ISP) namely AOL, DSL4U and British telecoms are be contracted to provide internet connection with a total of six (6) subscriptions accounts between the 3 ISPs, the subscriptions are used as follows • One connection for the VOIP

The current architecture of the Riordan Manufacturing Company Inc. Wide Area Network (WAN) and network security in place requires updated documentation. The purpose of this paper is to consolidate the existing information into a single format and evaluate the WAN and security documentation for an executive overview. Riordan Manufacturing, Inc. is an industry leader in the field of plastic injection molding. With state-of-the art design capabilities, they create innovative plastic designs that have earned international acclaim. Attention to detail, extreme precision and enthusiastic quality controls are the hallmarks of Riordan Manufacturing. With facilities in San Jose, California, Albany, Georgia, Pontiac, Michigan and Hangzhou, China, the company is heavily dependent upon their communication networks. The documentation produced by this analysis will give the management at Riordan Manufacturing an understanding of their current network topology and a baseline to evaluate security of the network.
In this topology, all nodes are connected to a central device, usually a hub or a switch. Each connected device has a dedicated, point-to-point connection between the device and the hub. The star network topology is by far the most widely implemented topology in use today.
The networks are controlled through use of a router. This router is the only device that sees every message sent by any computer on either of the company's two networks. The router ensures that information doesn't go where it is not needed. This is crucial for keeping large volumes of data from clogging the connections of other departments at MKS.

Over the past few years, Internet-enabled business, or e-business, has drastically improved efficiency and revenue growth. E-business applications such as e-commerce, supply-chain management, and remote access allow companies to streamline processes, lower operating costs, and increase customer satisfaction. Such applications require mission-critical networks that accommodate voice, video, and data traffic, and these networks must be scalable to support increasing numbers of users and the need for greater
...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
A data network is a telecommunications network that allows computers to exchange data. In computer networks, networked devices pass data to each other through data connections. These connections between the devices in the networks are established by using either cable or wireless media. Computer networks differ in the physical media used to transmit their signals, the communications protocols to organize network traffic, the network's size, topology and organizational intent. With the rapid technology era, upgrading the network is an important and vital change in this organization. It will involves lot of cost and time for the management and the users in the organization. But the benefit is really worth it. If the Upgradation is in the Insurance Industry then the main impact will be on the data security and data integration because the data in the company belongs to end users and contains vital information. SWOT Analysis is a useful technique for understanding and analysis this network upgrade project. It would help us to understand our: Strengths and Weaknesses, and for identifying both the Opportunities open to us and the Threats we could face. Below is my SWOT analysis for “Philips Insurance company”.
The data-link layer provides error-free transfer of data frames from one computer to another over the physical layer. The layers above this layer can assume virtually error-free transmission over the network. The data-link layer provides the following functions.
Figure 2.11 above shows the network topology in a single lab. In the lab, a star topology is used to connect a printer, a wireless access point and 50 personal computers with a single special device known as switch. Instead of using hub, a switch is used to identify which computer system is connecting to which port. Switch knows exactly where a frame is received from and which port it wants to send to, without increasing the network response time. Unlike a hub which divides the bandwidth among the systems when multiple PCs are broadcasting, switch enables system users to access the maximum amount of bandwidth regardless the number of PCs transmitting. Thus, a switch is considered as a better choice than a hub because it maintains the performance instead of degrading.
Networks in organisation are dynamic and complex entities which can be quite challenging to configure and manage. (Kim & Feamster 2013). These corporate networks consist of multiple routers, switches, firewalls, middleboxes and a particular advantage of network management is the ability to monitor the entire business network. As all the devices are interconnected with many event occurring simultaneously, problems with once device can eventually lead and spread throughout...
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.
Assigning the precise amount of network capacity in the right place at the right time is no simple task. Network Planners cannot afford to overbuild, as this would consume scarce investment resources that could be better used elsewhere. They also cannot delay expansion as this may result in poor service to customers and under-utilize other network assets. A balanced approach is needed in order to meet the rapidly growing and changing traffic demands. Advanced network planning and design software provides benefit to network planners in the following ways:
The network management plan and security plan is important to help the company figure out how they will improve its network and security procedures for the company. Planning involves outlining objectiv...
