Network Topology Design Essay

“Networks are all around us. They are in our walls, in the air. At schools, hotels, hospitals, even coffee shops. Always there, always on…This power exists today. In our routers. In our switches... . (Cisco, n.d.)

3: Network Layer: The use of network layer is switching and routing technologies. It demonstrates logical path and virtual circuits for transferring data from one node to

Layer 1: Physical - This is the level of the actual hardware. It defines the physical characteristics of the network such as connections, voltage levels and timing.

When setting up a network that will consist of many host computers, one of the first things that an administrator must do is to determine what class of networks that they must administer to a given business. This is the point where every administrator must know how to implement classful and classless IP addressing. A classful network is a network addressing architecture used in the internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Classful IP addressing divides the addtess space on the internet into five address classes. Each class is coded in the first four bits of the address. Today

Each campus will have a DHCP server to hand out ip addresses to nodes on the Curriculum network.

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

layer 1 | Hubs, repeaters, network adapters, Parallel SCSI buses. Various physical-layer Ethernet incorporates both this layer and the data-link layer. Token ring, FDDI, and IEEE 802.11. | - |

During this period, the network identifies the product and assigns the IP address or hostname of the product.

contains the case narrative, related figures, and a set of questions and problems. These do not have one unique solution. There are too many alternatives when dealing with LANs, WANs, MANs, BNs, and the Internet, so a reallife network design and development problem can have several workable answers.

To outface this problem Network Address Translation (NAT) method is used. This enables devices with private addresses to be connected to a public network address (e.g. Internet). This private address is converted to legal IP address, through NAT routers before traveling 11 “outside”. (See figure 4). Every device that is connected to the network has a unique IP address but this doesn’t mean that is permanent. Because devices connected to the network,

In order to properly address the Infrastructure upgrade of the Kamazon Network our group decided that an appropriate ip address schema that will take into account the idea that people will be using more than just a desktop computer. They will have tablets, laptops, departmental printers, and smart phones. This is also based upon the understanding that every Department will have at least two printers for the staff and one for the Manager/Supervisor or VP of that Department. So with that being said, we estimated that could be at least three or more accurately four ip addresses per employee. So we multiplied the number of users per department by the number of estimated devices that each

In line with standard procedures, Static IP addresses will be retained for servers and networked equipment as this allows for an easier collation and management of such devices at each site.

As this demand for dynamic and unpredictable data grows, more and more devices have to be added to existing networks and configured accordingly. The need of the hour is to regulate networks centrally and as a whole rather than configure individual network devices and gain more control to achieve flexibility in existing networks.

3 Not being a technical person, I am heavily relying on our text and other related literature. The fundamental to network addressing and numbering in an environment, despite the size or location, is following a structured model. A network designer should carefully develop, plan, manage, and document the network layer addresses. Since no accurate mechanisms exist for assigning network or subnet numbers dynamically, the network layer address numbers need to be well-planned, administered, and documented. There are benefits to observing this approach. The network will be easily managed, maintained, troubleshooting narrowed and isolated to the location, and the network will be scalable (Oppenheimer, p. 169, 2011).

The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper
