Case Project 2-1: Expanding the Network BackboneThe Ethernet option is the best choice in expanding the newspaper’s network back bone for several reasons: it is the most commonly used network architecture, it is scalable to accommodate growth, it is adaptable to a multitude of devices, support staff and tools are readily available, and there is minimal or no need to change the existing devises. This report will elaborate. Ethernet is the most common form of network architecture by far. Token ring and Fiber Distributed Data Interface (FDDI) technologies are very rarely used. Support would be difficult and/or expensive to get. The company would be under risk of isolation since most businesses, particularly our competitors, use Ethernet technology.The capacity for Ethernet technology is very scalable. Should the company decide to add new departments, minimal effort would be needed, depending on the network equipment initially installed, such as the router.Ethernet technology is ‘user-friendly’ to numerous devises; including: desktop computers, lap top computers, cell phones, tablets, WIFI, all types of printers, VOIP phone technology, and others. Reporters can print to their office printers from the cell phones or tablets in field.Since Ethernet is the most used network architecture, skilled technicians and tools are readily available. Whether the newspaper hires in-house IT support or out-sources contractors, there are many skilled people out there that know how to maintain Ethernet systems.

The reason I believe an Ethernet connectivity system would still work the best is because of how easy it is to upgrade our current system to incorporate the rest of the office into the network. Ethernet is easily the easiest and most cost-effective system to implement for the rest of the office. Since the network is already based through Ethernet, the rest of the office can just implement the system by just expanding on the current network by expanding the physical cable throughout the rest of the office.Since Ethernet has already been installed in parts of the office it offers easier expansion because the office already has a source to be expanded upon with our current star-bus topology which would involve only adding switches that could all be connected to the current backbone source which is already in place. So as long as we keep the network within the current standards of cable length, number of switches and devices attached to the network, it would create a successful network throughout the office.

Case Project 3-1: Choosing a Network ProtocolTCP/IP is currently recommended as it is the most widely used protocol suite and the protocol ofthe internet. All network traffic, whether it’s multiple PCs connected by a hub or two machineson opposite sides of world, is delivered via the TCP/IP protocol suite. This is the protocol usedwhen your machine receives an “IP address” that enables it to participate in network traffic. Itprovides efficient and reliable connections that can be routed across multiple networks, and aconsistent hierarchical naming system that provides a unique name for each device on the entireInternet. It also provides a complete suite of standard applications and services, including email,web browsing, file system sharing, individual file transfer, printer access, remote login, remoteprogram execution, and others.TCP/IP has many advantages in additional to it being the international language of networkcommunications. There are a wide range of network devices designed for use with TCP/IP. Thereare many troubleshooting and network analysis tools available for TCP/IP as well as mostnetwork professionals who understand TCP/IP.

Case Project Week 2 Network Protocol_1 – Case Project 3-1

2Case Project 3-2: IPv6 AdvantagesIPv6 addressing enables one IP identifier to be associated with several different interfaces so it can better handle multimedia traffic. Instead of broadcasting or multicasting groupings underIPv6, networks transmitting multimedia traffic designate all the recipient interfaces as the same address. Replacing class-based addresses, IPv6 is designed to be CIDR-compliant, so that addresses can be configured using a wide range of options.The Internet is currently undergoing a profound and complex migration to IPv6, which will lead to long-term global and individual benefits. The benefits of IPv6 are vast and far-reaching, but not necessarily in terms of instant payback.Twenty years ago, people scoffed at the Internet because they didn’t know the full benefits of it.They needed innovative companies to demonstrate its possibilities. Likewise the full benefits ofIPv6, with its ability to vary according to its requirements, size and structure, will be realized by innovative organizations who will achieve cost savings through more efficient and secure networks. Also, as IPv4 is superseded, the marginal costs of supporting legacy IPv4 systems rises steeply, but because of its extraordinary scalability, the marginal costs of IPv6 remain flat.Another important benefit for IPv6-capable enterprises will be enhanced communications with trading partners, especially China and India. This is because the US, with 5% of the world’s population, is assigned 36% of the IPv4 addresses, but China and India, with 36% of the world’s population between them, have only 8% of the IPv4 addresses.

Case Project Week 2 Network Protocol_1

Case Project 3-1: Choosing a Network ProtocolWhat Protocol do you recommend to this network, and what are its advantages?Based on the knowledge of networks that I have gained I would recommend using the TCP/IP application protocol. Each device/machine on a TCP/IP connection is identified with a name; these devices are also spread out throughout the network, and these connections can be across multiple networks. Many protocols and applications are available to use with TCP/IP.Some of these protocols are PPP, FTP, HTTP,Telnet, and TCP.Advantages of TCP/IP: Used on most networks and Internet, this makes the international language of network communications. It has a broad range of network devices designed for use. Used by most operating systems as their primary protocol.It has many troubleshooting and network analysis tools. A Large body of network professionals understand it.

Case Project 3-3: Monitoring the NetworkWhat should be implemented for network monitoring the main and outlet locations? How can network monitoring be made secure?

For the company to monitor the network at the main location as well as the outlet store, Nishida Kitchens would have to enact the Simple Network Management ProtocolVersion1,2, and 3 (SNMP). This will enable the admins associated with the company admission to monitor their networks movement as necessary. The SNMP functions autonomously on the network which means it would not entail a two-way connection to work, this also means that it would not hinder any other network activity.SNMP works first by examining the network movement and produces alerts of imperfect packets, as well as any faulty nodes and excessive network traffic. The system will allow network administrators troubleshooting capabilities remotely. Having this capability creates an advantage for their outer sites. One important SNMP based tool is the Remote Network Monitoring. This tool monitors LAN that used WAN connection, only employs SNMP, but uses remote monitoring from a special database built in. SNMPv3 authentication packets provide security through encryption. What this does is prevent the capture of packets and makes a more secure network.

Case Project 3-4: Establishing an E-Mail Server Nishida Kitchens is considering the implementation of its own e-mail server so that employees can exchange e-mail with one another and with others over the internet.What element is important to implement in the e-mail server so that messages can be transported over the internet? How does that element work?For an e-mail server to be established for a business or any other company toallow for the exchange of email through the internet, A Simple Mail Transfer Protocol(SMTP) would have to be established. SMTP is “the most common and popular email communication protocols, it provides intermediate network from the remote email provider to organizational email server and local user accessing it” (What is Simple MailTransfer Protocol (SMTP)? Techopedia). The SMTP consists of four important components in the system.

2-2: Creating a Network That Can Communicate with Other Networks

Networks are guaranteed to work because there are standards. A network communications model called the Open Systems Interconnection (OSI) guides all LAN, WAN, MAN andCAN communications. The OSI set the foundation for the guidelines that vendors follow when the design communications for hardware and software.

Case Project 2-3: Questions

About the OSI ModelBrett Mason, a new colleague with whom you are working at Network Design Consultants, is unsure about some aspects of the OSI model. He has a list of questions for you and asks that you develop a table that he can use as a reference for the answers. Create a table containing two columns and seven rows. Label the left column “Network Function,” and label the right column “OSI Layer.” Enter each of the following functions in its own row under the leftcolumn, and then specify the OSI layer that performs that function under the right column. Brett’s questions about functions are as follows:Which layer resizes frames to match the receiving network?Which layer performs data compression?Which layer ensures data is received in the order it was sent?Which layer handles the data-carrying signal?Which layer provides file transfer services?Which layer enables routing?Which layer enables the receiving node to send an acknowledgment?Answer:6Unlock document

The communication with and understanding of a new employee in any organization is vital to the firm’s success. Brett should thoroughly understand the technology and how it relates to the successful completion of the project. The creation and presentation of the table showing the relationship of the OSI model and the layer functionality’s will be important for Brett in designing present and future projects. Directing Brett to other sources of information such as the regulatory organization’s Web sites or documentation will also help Brett understand better. Brett can visit the IEEE, IETF, and other network-related regulatory Web sitesfor further information. There are also many different trade periodicals that Brett can consult along with numerous training courses from several different training groups

Case Project 6-1: Designing a Wireless Network for Roaming Team Members

o make it easier for any team member to access the networked computer resources when they’re not physically at their desk or in their office, I’d recommend adding multiple wireless access points throughout the college for each team, using the IEEE wireless networking standard 802.11n. This would complement the wired network which would be located in the IT office as the center location for the network with the various routers and access points to make it easier for team members to work in numerous areas of the building by adding a stronger signal, up to 650 feet, and speeds up to 900Mbps+ with the 802.11n. Each team member shouldalso be provided with WNICS to give them the ability of connecting wirelessly to make it easier to bounce around the office without struggling to access the networked computer resources.

Case Project 2-2 Network that communicates with other networks

Question: The management wants to know if there area any guarantees that the network you are proposing will communicate with other networks. What is your response?Answer: Ethernet is a widely used standard for networking. It is a very common and very popular way for businesses and homeowners to connect multiple networks to one another. Ethernet, according to theIEEE 802.3 specifications, is a LAN standard. What is the IEEE you may be wondering?

OPTION 2 Case Project 2-1: Expanding the Network Backbone

There is already a partial network backbone using Ethernet in the newspaper’s building that joins some of the administrative and advertising offices. Prepare a report or slide show that explains why Ethernet is still a good choice for the network backbone. The use of the Ethernet as a networking requirement, would best benefit The Franklin Daily Herald. Ethernet is a standard IEEE 802.3 LAN (local area network) line specification known as fast internet or 100BaseX. The Ethernet is most preferred installed LAN due the its capabilities for expansion, upgrades, high-speeds, wireless capabilities as well as its security. With the use of Ethernet as the business network at the Daily Harold, it becomes more affordable for the company when it comes to speed upgrades, due to the vast majority of vendors available through using Ethernet, and that there would be no need for the replacement of computers nor equipment in the end. The Daily Herald should also take into consideration to use Ethernet is the security potentials that it has for the network. Characteristically, access to the Ethernet data transmitted on the network can only be accomplished by those devices that are connected to that network, this making it more secure. If you take a look at the overall scope of Ethernets affordable low-cost capabilities for enhanced network speeds, security, and upgrade variables that are available, the use of Ethernet for the Daily Harold would be the best choice for their backbone. Also For the business using Ethernet also makes it easier for the business to centralize the management of the network to increase the overall functionality and create faster response times when issues arise (Palmer, M. J. 2013). Case Project 2-2: Creating a Network That Can Communicate with Other NetworksThe management wants to know if there are any guarantees that the network you are proposing will communicate with other networks. What is your response?Through the use of setting up a LAN (local area network) for the Daily Harold, with the network standards guided and established by the Open Systems Interconnection (OSI) network communications model.
