Netw410 Week 3 Lab 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 3: Network - The way that the data will be sent to the recipient device is determined in this layer. Logical protocols, routing and addressing are handled here.

1. Application (in terms of cabling infrastructure): The application layer is the OSI layer closest to the end user, which means both the OSI application layer and the user interact directly with the software application. When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists.. (OSI_model#Layer_7:_application_layer)

In this topology, The distributed systems are connected at different sites to loosely coupled with gateway system members. The cached data between different sites is entire to the applications within each distributed system. If any system becomes unavailable, the rest of the installation to continues and

Layer 4 is the transport layer and utilises common transport protocols to enable network communications. This may include the Transport Control Protocol (TCP) and Universal Data Protocol

Kudler Fine Foods will be embarking on a new project to implement improvement to its existing network infrastructure. The end result will be the installation of a WAN to connect all three store locations together to enable better communication and sharing of data. A new WLAN shall also be implemented in order to provide more flexibility in the stores and make added new systems and features easier in the future. Lastly with the new network implementations there shall also be a new VOIP system added to the multi-store network. The first section shall cover the network’s fundamental characteristics components, and

NOTE: Please write your answers to each question in a different color font to make this easier for the Professor to grade.

A Star topology is the second type of topology represented. This topology is easy to install as well as being easy to expand by connecting additional nodes or devices. Faults are easily detected and parts are easy to remove. In a Start topology, when devices need to be added or removed, it does not cause disruptions to the network. This type of topology is used for many different applications, ranging from small to large networks. (FCIT, Univ. of Florida)

Core The core layer is the backbone layer of the network running at high speed switching, transferring large amounts of data and also handling the requests of the distribution layer . This layer has high speed devices; the most implementations have layer 3 switches or high end routers. Its key characteristics are: redundancy, fast transport of large amounts of data, high reliability and availability, low latency. The core layer should not do any packet manipulation.

The last and final problem on the network is the UPS power unit installed at all sites. At this point this may provide enough power to the take care of the current network infrastructure, but this will not work for the new network design. This is vital to the network because, “If a computer is not receiving a consistent flow of electricity, damage can and often does occur.” (Fisher). Providing a redundant power supply will be vital to the network because having the ability to operate when power goes out will make sure that no information or data is

As for the cabling that would be required to get Gigabit internet, or 1000 megabits per second, that would call for either Category 5+, 5e or 6. Any one of those three is technically capable of supporting Gigabit speeds. All three have been out for some time now and it would be best to go ahead and spend the extra amount, although not too much extra, on the category 6 cable. If this is done, it is extremely unlikely that any re-cabling would have to occur for the foreseeable future (Lowe, 2002).

There are various options for connection of the RNC site to the rest of the operator’s network. In this study only the IP related options shall be studied, thus the only considered scenarios are layer 3 (routed, IP based) and layer 2 (switched, Ethernet) transport.

appropriate redundancy in ICN to enable a high level of reliability remains unknown. In this paper, we

The Modern Mouldings current wired infrastructure will be appraised based on the following qualities. Speed, Topology, Scalability, Cost, Reliability and Availability.
