Client/Server Network Design Essay

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.

The fifth layer is the session layer this establishes a connection,this layer makes and sets up the connection using co ordinates and could terminate conversations links. the session layer produces services that make authentication after an interruption and not only that but it can reconnect.and as well as the transporting layer it can also have the TCP and the UDP can provide services for all most all applications.An application layer is an abstraction layer that specifies the shared protocols and interface methods used by hosts in a communications network. The application layer abstraction is used in both of the standard models of computer networking; the Internet Protocol Suite (TCP/IP) and the Open Systems Interconnection model (OSI model).Although both models use the same term for their respective highest level layer, the detailed definitions and purposes are different.In TCP/IP, the application layer contains the communications protocols and interface methods used in process-to-process communications

This makes sure the data transferred is in the right order, error free and reliable from beginning to end. The Network Layer is the third layer of the model and its function is to interpret the network addresses into physical addresses and figure out how to direct them from the sender to the receiver. The next layer is the Data Link Layer, this is the second layer and it separates the data it receives from the Network layer into specific frames so they can be transmitted by the Physical layer. Frames are packages for moving data, they include the raw data, the sender and receiver’s addresses, as well as error checking and control information. This makes sure the frames are delivered to their destination without any problems. The physical layer is the first layer and the lowest, the protocols at this layer recognize and receive the frames from the Data Link layer. They also monitor data error and set data transmission

It is the software structure, which implements the communication function. The protocol architecture consists of a layered set of protocols, with one or more

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

Upon reviewing Kudler Fine Food network, it has been determined that a major network overhaul will need to be conducted to make sure that Kudler is brought up to speed with the latest technology. This is very important because if Kudler is unable to keep up with the technological advances then the company will fall behind. Making sure that Kudler is not only able to keep up with the advances with network systems it is also important to install the proper systems so that no money is wasted. What is meant by this is that if the improper systems and storage units are installed to only handle data over the next year this is

Layer 4 which is the Transport layer responsible for end to end connection. It parts and collect the data and is made into data streams. It ensures that the data is established and maintained. It also detects any errors found in the data while transferring as well as recovering those

Data will be created and used from all work stations on the network. The data will be produced by software application in a windows 7 environment on all work station and windows server 2008 on the server. Office 2010 professional (word, excel, power point, access and outlook) will also be utilized. Other data sources to be supported will be windows 7 accessories. The network cannot be accessed from outside the facility.

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 also acts against other types of malware such as worm, Trojan horses, backdoors, and spyware. The ESET NOD32 Antivirus 6 that I will utilize

The application layer: this layer allows different applications to communicate with each other’s. In order to exchange different data over the network connection, the protocols included in this layer set up the standards such as DNS, HTTP, FTP. The data coded in this layer will be encapsulated to transport layer for further packing.

First, we need to understand the difference between logical and physical topographical layouts. Logical layouts are how the data move across the network and physical layouts are how the network relates to its wires and hardware (Kevin Wallace, 2012). Note that how the data moves through the network is not going to be the same as how the data is physically structured (Michael Harris, 2008). The most coming physical topologies are Bus, Star, and Star-Wire Ring (Kevin Wallace, 2012). The most coming logical topologies are Bus, Ring, and Star (Kevin Wallace, 2012).

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

The ability to send and receive data efficiently is the most important objective of networking computers.
