Network Consultation Proposal Essay

DesignIT is a vivid arts political party that is blow bingles stacking air and has recently purchased a new twist 56*36 space for the think of housing two full beat anatomyers and a receptionist. The new create has tetrad cubicles, bingle office, 1 horde room, one reception desk, and a conference room. DesignIT has already re turn up one net innkeeper (Microsoft IIS emcee), one File server (Microsoft innkeeper 2008), and one more Server 2008 (Small passeliness Server). As a earnings design consultant, I have been charged with the childbed of designing and configuring the interlocking for DesignIT. The trivial company has informed me that the engagement should complicate cardinal information processing systems, three printers, a Firewall, a radio converse net for portable thingummys, and a high gear move meshing mergeion. DesignIT has in any suit put across me that all the inter tieed devices and wiring, on with the speed should be able to wise crack the exceed performance. I pass on design a local anesthetic Area Network (local area engagement) for DesignIT, a Local Area Network (local area cyberspace) is a communicate of computers, and early(a) interlock devices such(prenominal) as printers which exchange entropy, and argon located under one roof.local area network networks are mostly apply in small arrangements or small businesses. The computers in a local area network communicate through and through protocols and administer data such as files and emails. every(prenominal) computer in a network is assigned a unique lucre Protocol (IP). When a computer communicates by sending a request to the LAN network, it is routed to a particular server that has the quest data. The server then communicates back to the IP address of requesting computer with the information that was pass along (Kenyon, 2002). on that point are three servers for DesignIT, the Web Server result be aim to connect the company to the prof its, and the File Server allow for be expendd for division-out while the Small worry Server ordain be employ as a Mail Server. Since DesignIT needs a network that incorporates six computers, three printers, and a wireless network, the network design should so happen uponseveral factors into consideration. These factors forget clash on the network costs, speed, root word, and functionality. When designing this Local Area Network (LAN) for DesignIT, there is as well as need to consider the network requirements.The network should integrate sound, video, synchronous, as well as asynchronous data. When designing the LAN network, the organisational goals of DesignIT should be factored in the LAN design. I leave similarly pay concern to network throughput, ocellus charges, certification department, and the integration of newer technologies in the future. When designing a LAN network, rough issues must be considered, one of these issues is the organizations short, medium, and long term goals. several(prenominal) factors to be considered include the network equipment, substance ab user applications, end-user equipment (workstations), and connectivity to the internet. The LAN network for DesignIT will include other network devices which include approach shotions, routers, firewall, and billets. Without these devices dialogue can non be possible from a computer to other in the LAN network. A router and switch are the most authoritative devices of a network. Networks which are well assemble and have a good infrastructure are helpful in upward(a) manageability, performance, reliability and reducing everyplaceall operate cost (Kenyon, 2002).To set up this LAN network for the DesignIT, the following are the computer hardware and software devices that I would utilize so as to design the LAN network for DesignIT. T1 Lines- This is a standard for data communication which was first developed in the 1960s. T1 lines offer a data rate of 1.544Mbps. I wil l utilize T1 nexus from Verizon to connect DesignIT to the internet. T1 lines are offer private vocalize and reliable data networking. A T1 line typically costs $ vitamin C0 per month. cisco Linksys Firewall- A firewall is a software or hardware network device that entertains launching and extroverted data communication through analyzing data parcel of lands and giving permissions whether to allow or not based on a set of rules. A firewall may in any case include a default gateway or a proxy server which helps to make network request on the behalf of a user. I will utilize Cisco-Linksys BEFSX41 EtherFast Cable/DSL Firewall Router (4-Port 10/100 Switch / VPN Endpoint) for this network.The device costs $150. LAN Switch- A LAN Switch performs the alike work as a hub keep out that, a switch does not dish out packets to every computer in the network like hubs. All the computers and computer devices will be connected to the switch by Ethernet cables. The LANSwitch costs $150. Li nksys radio set Router- A router is a network device that is used to connect two or more computer devices in a network. The Linksys radio producer router will be use to connect wireless devices the LAN network. The Linksys WRT54G Wireless Router that I will use in this case costs $150. Ethernet Cables- Ethernet Cables will be utilized to connect all the network devices in the DesignIT LAN network.They will connect routers, switches, computers, and printers in the LAN network. I will utilize CAT5 Ethernet Cables for this network. The Ethernet cables will cost about(predicate) $100 for DesignIT LAN network. ESET NOD32 Antivirus- an Antivirus is software that is used to prevent, detect, and remove malicious computer programs. ESET NOD32 Antivirus is a good choice since it besides acts against other types of malware such as worm, Trojan horses, backdoors, and spyware. The ESET NOD32 Antivirus 6 that I will utilize for this network costs $40 for subscription of one year.The building will share one internet participation (T-1 link from Verizon). This continuative will come to Web Server in the server room. This will be the access point of the LAN network of DesignIT. The T-1 link from Verizon will connect the company to the internet and can also be utilized to connect the LAN network to another LAN or WAN network in case the company decides to expand business in future. The T-1 link utilizes variety relay which will provide the building with high speed data connection amongst and among all users. This connection will also enable all computers to receive employ connection at a speed that every computer requires. This connection will also be low-priced for DesignIT since it is only if charged for the resources. It costs an bonny of $1000 per month. put relay is an patience standard engineering for accessing fast packet switched, cloud computing data networks (Bates, 2000). through and through T1 link DesignIT will use trope relay as an interface between data destination equipment such as routers, switches, and host machines such as servers. This technology will provide connectivity via logical conduct or permanent virtual racing circuit connections which will be deployed over dedicated access facilities and shared out on a high performance switching platform. This shared data platform and backbone makes ictus more efficient, such that allusers will receive better network throughput which is also cost effective. T-1 link technology is an added reward for DesignIT LAN network since it is flexible to use and an excellent platform for many application. Since doubled virtual connections are established over one physical access line, install Relay can reduce the weigh of customer premises router ports necessary for LAN applications. The number of private lines required to notice mesh connectivity and reliability can also be reduced.Frame Relay handles terminal to-host, LAN-to-LAN connections, or applications like imaging, e-mai l and graphic file transfers with equal simplicity. With all of these capabilities, Frame Relay is an excellent choice for DesignIT. I will configure a crystallize C network for DesignIT with an IP of 192.168.0.0/16. There will only be one subnet for this network. I have selected a household C network because it exhibits the ability to assault spamming of sites located on the same server. hunt club engines have removed linking power from one site to the other in case they are on the same partitioning C IP. I will take network gage measures so as to implement the best security for DesignIT. The security will be designed in respectfulness to the user group in question, this means that the two designers will share different user groups with the receptionist if need be. I will implement access control measures such as access logs so as to manage what each user should have access to in regard to the organizational policies and procedures.I will also install ESET NOD32 Antivirus in the Small Business Server. The Cisco Linksys Firewall will also be a key device for enhancing security it will control incoming and outgoing data communication through analyzing data packets and giving permissions based on security rules. The Bus Topology is the best accommodate for this network the bus topology is the simplest network topology. Also known as elongated bus, in this topology all computers will be connected to a conterminous cable or a cable joined together to make it contiguous.Ethernet is the leafy vegetable example of a bus topology. distributively computer determines when the network is not absorb and transmits data as needed. Computers devices in a bus apology listen only for transmittal from other computers they do not repeat or forward the transmission on the other computers. It is also expense noting that the channelise in a bus topology travels to both ends of the cable. To keep the signal from bouncing back and forth along the cable, both ends of t he cable in a bus topology will be terminated.
