Networking Software: The two most popular cables in networking are the twisted pair (10BaseT) and the thin coaxial cable (10Base2). Figure 3-1 illustrates the roles of the various devices that form the network infrastructure of a large-scale enterprise network, and Table 3-1 summarizes the features Since packets are sent in bits, it is therefore not necessary to reserve a path during communication as different packets follow different paths and are later reassembled at the receiver’s end (Hekmat, n. d). It is very likely your business uses some degree of telecoms technology, whether that’s phone lines and headsets, or computers, smart phones and the internet. FEASIBILITY STUDY . For larger distances, the network is either referred to as Metropolitan Area Networks (MAN) or a Wide Area network (WAN). (2010). In example, a network that includes Juniper Networks' switches and HP ProCurve's data center management solution would be considered a hybrid network. Up to date, education still continues to be one of the areas where computer networks are greatly applied. An example of an RJ-45 connector is shown below. Facilities that mostly house infrastructure such as data centers. Ad hoc wireless LANs. 2 Network Design For communication and exchange of data between any two nodes to occur, various underlying technologies must be in place and the interconnection is not as simplistic as it often appears. also offered here. about. Repeaters therefore operate on the physical layer (layer 1) of the OSI model (Network Hardware Components, 2007). "Network Infrastructure and Security" paper states that virtualization and cloud computing are used in an immense manner with the aim of ascertaining that resources are StudentShare Our website is a unique platform where students can share their papers in a matter of giving an example of the work to be done. For example, in a really small network with one switch and a firewall and perhaps a single wireless access point, there isn’t much to document. A definition of IT infrastructure with several examples. 7. References AllBusiness. Years down the line, the third generation mobile telephony (3G) has emerged and is able to handle both data and voice applications. Technically, both private and public could be LANs, MANs or even WANs but often, public networks tend to be WANs. com/networking/Lesson01. This includes foundational networking hardware, software, services and facilities. The network infrastructure is responsible for maintaining both internal and external connectivity of the internal and external systems. Workers may be taking orders for products that are out of inventory or even discontinued. Services of the failed terminal can still continue to be offered from other terminals as the functions are distributed (Coulouris, Dollimore, & Kindberg, 2005). One such example is Google cloud – It is a suite of public cloud services offered by Google. In light of the above, this paper will evaluate network infrastructure and its business application. As the dominant supplier of Enterprise Resource Planning (ERP) software, we can assume SAP set the agenda in the packaged software market and so provide a useful point of reference for the industry as a whole. Boston: Addison-Wesley. Some infrastructure networks only contain network equipment from one vendor -- like Cisco -- because the pieces are interoperable and would therefore avoid mis-communication between devices; it could also create a faster network (in theory). The World Wide Web , E-mail , [39] printing and network file sharing are examples of well-known network services. Network infrastructure therefore refers to the architecture in terms of the equipment as well as the connections that in total make up the entire network. However, losses resulting from network failures can be serious and even detrimental to the business. In a Messaging Server deployment, determining your network infrastructure from the project goals ensures that you will have an architecture that can scale and grow. With more advancement in technology, it is nowadays possible to set up wireless networks that are faster in data transfers and enhance mobility. Routers are placed at the network layer (Layer 3) of the Opens Systems Interconnection (OSI) model. Diagramming your IT infrastructure would allow you to take an inventory of the resources By continuing we’ll assume you’re on board with our cookie policy. Prior to the widespread of the networking that eventually led to the birth of the internet, links were limited by their nature and communications could only take place between two stations. Retrieved July 5, 2010, from http://davestechsupport. Fig. Advance in technology has seen Digital Subscriber Lines (DSLs) and modems for home use being integrated with routers to enable multiple home computers to access the internet (Network Hardware Components, 2007). Further, this layer checks for errors from the physical layer and does synchronization. The three common types of computing endpoint. It is very likely your business uses some degree of telecoms technology, whether that’s phone lines and headsets, or computers, smart phones and the internet. Retrieved July 6, 2010, from http://www. The following are common examples of network infrastructure. Retrieved July 5, 2010, from http://www. Network configuration management systems can use this template to verify current configurations and alert you when out of policy. Public networks on the other hand are accessible to the general public but only upon payment of a connection fee. +44 (0)1865 589216 Why You Need a Computer Network. A typical example of distributed systems application is the banking systems explaining how one is able to withdraw cash from any Automated Teller Machines irrespective of their specific bank branch. The short answer is that it should include everything that’s relevant—but what that means varies between networks. The IP addressing for systems on the network and the quantity of network components has to be decided. View network and IT infrastructure documentation examples generated by our documentation tool XIA Configuration. Cisco IOS is the most critical part of network infrastructure. (546). These packets are passed from one node to the intermediate next, which temporarily stores it, waiting for the receiving node to be ready to receive it. Dave. This is done mainly through use of offsite servers or other backup systems. Private networks belong to the organizations that maintain them such as banks, airline companies, hospitals, insurance companies and so on. Technology refresh cycles in the IT infrastructure realm can be as short as 2–3 years or as long as 5–7 years. 5 Source: NOSPINGroup Having connected the different personal computers, a hub is then used to connect them centrally. com/ NOSPINGroup. Computer network architectures and protocols. These were deployed in the early 1980’s and it was not until 1990s that the second generations (2G) were deployed. (1989). In addition they have connectors called RJ-45 connectors, that are synonymous to that of phone cord connectors. It isn’t necessarily easy, particularly if you have a deployment that involves two or more types of infrastructure, and especially considering a geographically distributed setup managed with load balancing and failover mechanisms.. Use them as templates to get you started. Network infrastructures can be built through the combination of wires and no wires! (467), 4.9 The implication to that section of the economy that can actively and creatively make use computer networks to accomplish various business needs is even more momentous. freepctech. According to Bellis, little computer networking can be traced back to 1950’s and formed the foundation on which the internet is built (Bell, n. d). They can be used to document a simple computer network for a single home or a complex technological infrastructure for an entire city. In this model, a layered archtecture of network is proposed, with each layer having a specified function, protocol and behaviour.

For a whole nation, it includes all the physical systems such as road and railway networks, utilities, sewage, water, telephone lines and cell towers, air control towers, bridges, etc. The delivery depends on the session layer (Layer 5) which enhances connections between an application, initializes and terminates connections. This is accomplished by examining the header of a given data packet and then making a decision on where in the next hop the packet should be sent to. It might be enough to put everything in a single diagram. FEASIBILITY STUDY . 2.
