Network Protocols

For this question I would have to go with the WLAN Star topology, the main reason for using the WLAN is for your wireless users to be able to connect to the network via an access point. Other reasons for using a WLAN, you would be able to have the ability to have the pc’s connected via CAT 5 still connect to the network. Security is a big issue for your company, the purpose of that would use the WPA, IDS/IPS, proxy servers, packet filtering firewalls that are locked a room like we have in Amazon, it’s a secure badge and pin combination room called out MDF room that is always cool with 2 cooling systems in there it have…

Web or Mobile System

As a network engineer it is very important to keep the network available for users at all times. “A highly available network means that the network and the applications that are used on it are both operational and accessible at all times” (CiscoPress 2008 p. 124). Working as a network engineer I am always on call because there is someone always using the network. “An always on facility is needed to maintain the business-critical apps” (Volonino 2011). The network is monitored 24 hours 7 days a week even if no one is scheduled to be in the office we still have to monitor the network to make sure there are not outages are hiccups along the way. If there is…

Managing Networks

Produce a report that justifies the need for network managers to undertake routine performance management activities. Please ensure that your justification for these activities relates to reasons of efficiency and how they affect the quality of the service provided. Activities could include (but are not restricted to) 1. Scheduled backup of data The reason why it is important to scheduled backups of data is because data to a business can be very important to them. This is why data should be backed up regularly to ensure data can recover easily also data in some business might change frequency so this is another reasons why it should be backup regularly. The best time to perform a backup is when the network…

Internet Protocol version 4 (IPv4) Security

IPv4 is an end-to-end network model that supports the multicast operation. Multicast operations or communications involve information transfer from one node in as single transmission to multiple receivers within the network. Moreover, it facilitates the broadcasting of multimedia information like videos and audio teleconferences. IPv4 utilizes MAC addresses and IP addresses to send data packets within and outside the Local Area Network respectively. For security purposes, routers are used in the interconnection of multiple networks to map the IP addresses to related MAC addresses. IPv4 uses 32-bit addresses that are divided into octets, each octet separated by a period. This gives different address ranges that are used for different purposes. This protocol establishes the use of group access controls, router…

Incident Response

Any network can be subjected to security compromise. There is no amount of coding or access control that can ultimately prevent an attack to a network. However, there is a need for any organization to ensure that their networks are safe and their incidence responses are effective. There are many tactics and tools that are employed by attackers to evade any detection by the investigation or incidence response teams, remain anonymous and to avoid attracting any attention by looking like normal users. If this fails, the attacker has the ability to degrade the system to make investigations more complicated. It is also important to note that the attackers are always technically more advanced than the security staff managing the network…

How Interconnected Networks Work

The concept of interconnecting networks entails ensuring that the set network structures enables communication and flow of information based on the way in which the network structure is organized. The working of interconnected networks involves integration of diverse network protocols and procedures (Battista, Patrignani, and Pizzonia 2003). Working of Interconnected Networks Domain name services, internet protocols, routers, and switches are some of the network protocols which are normally utilized when interconnecting protocols. According to William (1992, pp. 190-205), when interconnecting various networks, there is always a need to chose the correct routing protocols in order to ensure maximum utilization of the scarce network space and related resources. In networking a system with the intention of ensuring interconnection, internationally recognized standards…

Supply Chain and Distribution Network

This paper describes a framework for designing the distribution network in a supply chain. Various factors influencing the choice of distribution network are described. We then discuss different choices of distribution networks and their relative strengths and weaknesses. The paper concludes by identifying distribution networks that are best suited for a variety of customer and product characteristics. this paper addresses the distribution network design problem under a supply chain system that involves selecting the optimum numbers, locations and capacities of plants and warehouses to open so that all customer demand is satisfied at minimum total costs of the distribution network. We develop a mixed integer programming allowing for multiple levels of capacities available to the warehouses and plants. The paper…

Ping Sweeps and Port Scans

Recently, it was brought to my attention that there are concerns about some activities on the network that can be considered less than trustworthy. Specifically, the concerns are regarding network traffic called ping sweeps and port scans. I’m putting together this paper to explain how ping sweeps and port scans impact our network traffic. First we must understand what these two things do before we can understand how they are used to impact a network. I’ll start with ping sweeps. A ping sweep is a signal that is sent to a range of machines on a network to simply see if there is a reply back. This is done via an ICMP Echo request that is sent to each machine….

Network Measures

The average degree is a measure of how many edges are in a set. In network measure, it helps in the average degree of all nodes given that it shows how many adjacent nodes the network has in average. It is calculated only when the network has not less than one edge connecting the nodes. In calculation of the average degree, two identified nodes which are adjacent i. e. I, j. Where I and j are not equal, then the set of all neighbor nodes will be denoted as a degree. Thus in order to find the average degree, all degrees are summed up and later divided by the total number of nodes in the network. The average degree explains…

Network Infrastructure

A computer network refers to the infrastructure that allows two or more computers, often called hosts, to communicate with each other and share information as well as other resources. This is usually achieved by defining a set of rules known as protocols which must be observed by all the participating hosts. A computer network is made up of various components and the fundamental layout of both the hardware and software that determines how the network works constitutes the network infrastructure. Network infrastructure therefore refers to the architecture in terms of the equipment as well as the connections that in total make up the entire network. In light of the above, this paper will evaluate network infrastructure and its business application….

Hardware vs Software Routing

A router can be defined as a device that connects two or more than two computer networks and selectively exchanges packets of data among them. Every packet data encompasses address information that a router can use to find out whether the destination and source are on the same network, or if the packet data must be transmitted from one network to another. Through projecting routing needs and network traffic centered on the types and number of applications and hardware devices used in environment, one can better choose whether to use a software router, a hardware router, or a combination of both. When talking about hardware and software router, there are numerous advantages hardware router has over software router. Few of…

Network Hardware

Choice of good network hardware will depend on a number of factors. First it has to be planned properly to allow growth without adversely affecting future business. The design of the network should ensure sufficient performance, availability and security. All this aims at providing enough information and processing of transactions for all its users. A list of users who will access the net has to be generated so as t determines the capacity the hardware will be able to support. A list of severs that need network connection should also be developed. Mid and high end servers should be selected. Server consolidation should be prioritized as a means of minimizing costs. The company will save much on power and floor…

Snort and Wireshark

1. When running Snort IDS why might there be no alerts? There are couple reasons when running Snort IDS there might be no alerts. The first one could be related to settings because the administrator has to set Snort IDS to its optimum settings in order to get any alerts. Since Snort works by ruleset, it can be mistakenly set up to a port other than what the network is using. The mistake can be done by either keeping the Snort default settings, or when users try to adjust them to their own network requirements. The point is when changing Snort default settings to rules other than what the website provided, the administrator might have disabled a packet sniffing on…

A better representation of the network

Centralization sums up my primary reason for implementing Active Directory. The Active Directory structure makes it possible for you to achieve truly centralized management of users, regardless of how big your client’s network has become. If you’ve worked with Windows NT before, you know that in Windows NT a domain is a completely independent entity. While it’s possible to create a trust relationship between domains that exist on a common network, the domains are never truly integrated with each other because there is no higher authority that manages the domains. The situation is different with Active Directory. Whereas the domain level was the highest level of abstraction in Windows NT, the highest level of abstraction in Windows 2000 and 2003…

Wireless radio signals

Coverage area: The space in which the wireless radio signals in one wireless LAN can effectively reach and be used to send and receive data between the WLAN’s APs and its clients. Shared bandwidth: A term referring to how some networks must share the right to send data by taking turns, which limits the total number of bits sent by all devices (the network’s total capacity). Wi-Fi: A term created by the Wi-Fi Alliance as part of its overall wireless LAN branding and marketing strategy; this term has become somewhat synonymous with wireless LAN over time. LAN edge: A reference to the part of the campus LAN with the end-user devices and the switches to which they connect, through an…

IP Address Schema Design for a Medium-Sized Business

IP Address Schema Design for a Medium-Sized Business The following IP schema is designed to fit the needs of the Warehouse Company. The company has purchased and installed all of the required equipment for the network infrastructure. After consulting with their design team and gathering the required documentation and network designs, we are ready to proceed. The network design requires an IP schema that will minimize the cost of public IP addresses. Due to this requirement we will use a Class B IP address solution with a default subnet mask of 11111111.11111111.00000000.00000000 or 255.255.0.0. I am calculating the need to have 2 possibly 3 public IP addresses. In order to meet the IP requirements for the company’s 367 devices that…

Manpower and Demographics

The two areas which the corporate would be looking to for change and reform in the healthcare sector would be to cover the greater portion of the uninsured and the under-insured and to bring down the spending in the healthcare sector. One of the companies that are encouraging the involvement of the uninsured in the health insurance coverage is the international pharmaceutical giant Astra Zeneca. It is the leading pharmaceutical company in the world and in the US more than 12000 people work for the company. The company teamed with Christiana healthcare (a leading non-profit healthcare provider in Delaware) to provide insurance coverage to the uninsured employees of the company in Delaware and also the people of Delaware. Not only…

The AI Revalution

Steven Levy is a senior writer for Wired and author of many books, including In the Plex: How Google Thinks, Works and Shapes Our Lives (Behrens and Rosen 209). In his essay “The AI Revolution is On” published in Wired in December of 2010 Levy distinguishes between two visions of artificial intelligence: the kind of AI currently in place and the machines that will think First, Levy gives a visual picture of how robots organize a warehouse. He explains that a company called Kiva Systems outfit similar facilities such as Gap, Staples, and Office Depot; the system can deliver items to packers at the rate of one every six seconds (209). Levy claims, “Today’s AI doesn’t try to re-create the…

The difference between obscene and indecent materials

Obscene material, “is not protected by the First Amendment,” (361) to the Constitution and cannot be broadcast at any time. On the other hand, indecent material is protected by the First Amendment and cannot be banned entirely. It may, however, be restricted in order to avoid its broadcast during times of the day when there is a reasonable risk that children may be in the audience. According to the U.S. Supreme Court, to be obscene, material must meet a three-prong test, “(1) an average person, applying contemporary community standards, must find that the material, as a whole, appeals to the prurient interest (i.e., material having a tendency to excite lustful thoughts); (2) the material must depict or describe, in a…

Marketing Strategies for Cell C

It has been argued that “strategic marketing planning can be viewed as the solution to multitudinous issues which face modern management” (Haris, 1996). Indeed, it is often contended that the process of strategic marketing planning is crucial since planning determines what must be done in the future whilst giving an opportunity to test what has been achieved against the framework of the existing plan. However, it is universally acknowledged that not only is planning far from simple but also that few organizations plan well (Piercy, 1997). As Cell C, we intend using our marketing plan as a road map, to plan our course and help us reach our goals/destination. Typically a marketing plan should consist of information about the company…

UMUC Frederick MD Network Proposal

The network IP addressing scheme for the Frederick MD building should be designed to ease network management. A well thought out network subnet design enables administrators to quickly locate computers by IP address by building floor and room, and whether the computer is a server, a student computer, staff computer or instructor’s computer. A proper subnet design will also minimize broadcast traffic that decreases network performance, by reducing the total number of computers allowed in each broadcast domain. A proper subnet design will also provide for efficient use of IP addresses by including only the number of IP addresses in each subnet necessary to support current computers plus a few additional IP addresses for immediate expansion when required. To differentiate…

Heidi Roizen Case

1. Describe Roizen’s network (including her reasons for developing her network) and how she developed it. Roizen’s young adult life shaped the reasons as to why she was going to become independent and self-sufficient. After suffering the tragic loss of her fiancé she set out to build a career and learned very early on that building connections with high-level people was something she had a talent for and something she ought not to miss out on when given the opportunity. Roizen knew she wanted to be in the technology industry, but with a creative writing degree she had limited options of jobs to choose from. At Tandem computers she wrote the internal newspaper serving as a link between the executives…

Intro to networking

1. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. Looking at a particular floor in a particular building, all the devices connect to either a single Ethernet switch or single wireless access point, both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN? C. All Ethernet user devices can be up to 100 meters away (but no farther), while WLAN devices must typically be closer than 100 meters. 2. IEEE 802.11 standards define a maximum speed for an individual transmission, with some variables that affect 802.11n speeds. Assuming that 802.11n uses the narrower…

IP Addresses Classes and Special

Use IP Address Space In a computer network internet protocol is used for communication, to each device such as printers and computers a numerical label called an IP (Internet Protocol) Address is assigned. There are two functions of an IP Address a host or network interface identification, and also provides a location addressing. The basic elements of a network are the IP Address and Subnet Mask. There is also switching and routing which after you connect devices to switches and routers, data packets can be moved across the network. The Internet Protocol Version 4 (known as IPv4) is a protocol highly used even today, this IP Address consist of a 32-bit number in decimal or binary in four parts. In…
