Layer 2 Domains Paper

This is a network proposal to connect six computers and two printers. The purpose of the project is to ensure the six employees can be able to; share files electronically print to both laser printers access each other's calendars and share an Internet connection.

In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.

In the design, the topology used is a star topology. The computers in every office or classroom are linked to the central device known as the switch. The star topology leads to the expansion of the network without any disruption. This defines the use of a hub, a router or a switch to interconnect various computers together. All the workstations in this topology are connected with a connection of point-to-point to the central device. The data is first passed through the primary device before reaching the planned destination. Hub controls and manages the whole network. The hubs connect several nodes that are present in the star system. The hub acts as the signal booster (Elhakeem, 2010).

There are various types of equipment that the company should look for when considering this network. The first item to look at when considering equipment is the Operating system and software that we would need. Next, the group took into consideration the type of server the company needs to make this network a reality. Another thing that we looked at is the possibility of having ThinClients over regular desktops for all workstations. Of course, it was taken into consideration that some employees would not want ThinClients. So, we show the type of tower we plan to place into those spaces, along with any peripheral device for both. Then, we will look at the network devices that will go into each building that include switches, routers, repeaters, hubs, and wireless access points. Finally, the group will note guidelines for choosing a local ISP at each site. Each Item outlined helps to build a network based on the specifications given by the company.

The work that will be performed will include the design and installation of a fully switched star network. This includes the installation and setup of all the network devices, cabling and interfaces but may be limited to workstations, devices, servers, switches, routers, racks and all related software.

Star – All computers and devices are connected to a centrally situated hub or switch. The hub or switch collects and distributes the flow of knowledge at intervals the network. It’s higher to use a switch than a hub as a result of a switch transmits the info to the supposed recipient instead of to all or any hosts on a network.

In the technological field of computers, a spanning tree protocol is a combination of networks which are used so that they can ensure that there exists a system for the Ethernet networks that have no loops in their layout. It has one primary goal in such a network, and it is to prevent all bridge loops and radiation that may be caused about by broadcasting through the consecutive use of these network protocols. This translates to spanning tree protocols creating an environment for network designs where they can include redundant links present in the case that the user may require a backup if the primary route used to access the link fails to work. The reroute of the links is done with less danger presented by the bridge loops and reducing the need for enabling and disabling these backup links. According to

The objective of the topology control algorithm is to adjust the transmission power to minimize interference, which is contradictory to the requirement of delay constraint. When transmission power is increased to reduce the delay, which increases the number of neighbors covered by the transmission range and causes more interference from other active nodes in the network. In order to reduce packet loss and improve the throughput by adaptive-FEC technique can be incorporated with DCHS

In a redundant mesh topology network devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network. A mesh network with redundant connections is an example of a redundant topology. The level of redundancy can be measured by network connectivity.

The network topology is shown in the Fig. 1. It consists of TCP sender and TCP receiver and a router. Node n0 and n1 is source node, node n3 is a receiver node and one finite buffer router node n2. Source n0 and n1 use TCP protocol and ftp as traffic. The link between n2 and n3 is called bottleneck link. The link n0-n2 and n1-n2 are full wired duplex link with bandwidth of 2Mb and delay 10ms. The bottleneck

Main Building – will require 7 computer stations with the most recent version of Operating System to ensure compatibility and networking capabilities between each stations and the ability to communicate between the two locations. They will require three servers, one for web hosting, one for database management and one for emergency failure of any one server. These stations should be networked to communicate with one another for proper data connection especially in the event of any one computer station crashing. Each work station will need to be linked to each server for web hosting and data backup. The cabling used for inside the main building should be 100Base TX cat 5 UTP, for Wi-Fi and WLAN with guest access that is highly secure and reliable, we recommend a device that is capable of supporting up to 15 different users with 450 Mbps. There needs to be 4 printer services in this building. Printer 1 should have

In the Merriam-Webster dictionary, a star is defined as “a natural luminous body visible in the sky especially at night.” Stars make up the brightest masses in the universe. Take the sun for instance, a big fiery ball of gas that provides light and life to the whole entire world. In the biblical story of the Magi, the three wise men follow a shining star which leads them to their light and savior, Jesus Christ, a baby who brings brightness to the whole world. A star is more than just a ball of gas, a star is a sign of hope, dreams, and courage. A star is the light at the end of the tunnel that makes the world just a little bit happier, a little bit stronger, and a little bit brighter, and no matter how small, one star can still brighten a midnight

The campus redesign we propose that we use all 3 of the Cisco Catalyst 6500 switches and we allocate one switch for the design department, one for the Human resources and one for marketing and sales. This will help optimize and departmentalize the switches for easy access and design simplicity. We also would like to have each switch connected to 2 routers each, this will help with redundency and help take care of the issues that the architects, engineers and employees keep reporting slow response times. To help with internet crashes and speeds we think that the company should

The proposed network is designed for the UMUC new building in Rockville. This new building will have some administrative offices, lecture rooms, library, and computer labs with an open Wi-Fi. This new building will have total six computer labs that will be used for instruction. Each of these labs will have 25 computers, 23 student computers and one instructor computer, one server in the closet and in addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students for doing their own purpose like homework. In Student Computer Lab there will be 30 computers and a server in the closet. There will be 10 computers for student’s use and 5 computers for Library staff in the library so they can access to the library resources for staff use, with the exception of the admissions office, which will have five computers. There will be six class room which will have a computer for instructor’s use. Finally, there will be 7 offices in the building and each of these offices will have one computer. There will be two server rooms, one on the first floor and another one on the second floor. There should be at least 3 separate networks: Administrative, Instructional, and Public. All staff-accessed computers will be on the

I choose the devices needed for the new implementation: Cisco Catalyst 6500 router and 2800 series four switches will be utilized. Here is the cost of effective access switches that are capable of VLAN, DTP, DHCP, RSTP, PoE, and furthermore, price can range from $1,400-$3,500 dollars each. These switches offer integrated security including network control and quality service, they also offer redundancy to provide and deliver intelligent services for a networking edge. Therefore, they include flexibility in the routing series as increased port density which could induce a rapid growth in networks without any additional cost at any time. However, the more capacity a device may have the more beneficial it will be to the administrator user, when setting up any secure measures throughout the configuration process of vlans and networks. The network accessibility will be ensured throughout the provision of redundancy of routers throughout the xACME network on each site or trade school. Although, optic fiber cables will be used to connect all layer 2 and 3 switches and servers, spanning tree protocol will be set on switched to address to eliminate any bridging loops from entering into any
