Connection technology[ edit ] Many technologies are available for wide area network links. Figure Example of Trends in Campus Design Layer 3 networking is required in the network to interconnect the switched workgroups and to provide services that include security, quality of service QoSand traffic management.
Leased lines can be very expensive. Determining your networking requirements Designing Campus Networks A campus network is a building or group of buildings all connected into one enterprise network that consists of many local-area networks LANs.
Consequently, network Wan design paper 1 generally deploy a campus design optimized for the fastest functional architecture that runs on the existing physical wire.
The speeds that people can currently use range from Design options[ edit ] The textbook definition of Wan design paper 1 WAN is a computer network spanning regions, countries, or even the world. You can use a Token Ring switch as either a transparent bridge or as a source-route bridge.
Hubs were for wiring closets, and routers were for the data-center or main telecommunications operations. Although the wiring and protocols of a campus might be based on WAN technology, they do not share the WAN constraint of the high cost of bandwidth.
Network designers are now designing campus networks by purchasing separate equipment types for example, routers, Ethernet switches, and ATM switches and then linking them. As Figure shows, these switches are usually installed to replace shared concentrator hubs and give higher-bandwidth connections to the end user.
Routing integrates these switched networks, and provides the security, stability, and control needed to build functional and scalable networks. However, upgrading the physical wiring can be expensive. Consequently, it was rare to make a hardware design mistake.
Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. ATM switching technologies ATM switching offers high-speed switching technology for voice, video, and data.
Traditionally, Layer 2 switching has been provided by LAN switches, and Layer 3 networking has been provided by routers. This is the base fabric of the network. Its operation is similar to LAN switching technologies for data operations.
At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other.
New developments in technologies have successively increased transmission rates. Many WANs are built for one particular organization and are private. They might also upgrade wiring to meet the requirements of emerging applications. Increasingly, these two networking functions are being integrated into common platforms.
It is possible to separate these technologies and build thoughtful designs using each new technology, but network designers must consider the overall integration of the network.
The distinct characteristic of a campus environment is that the company that owns the campus network usually owns the physical wires deployed in the campus. Cisco Systems offers product solutions in all these technologies. Table summarizes the various LAN technologies required to build successful campus networks.
After the wire is installed, bandwidth is inexpensive because the company owns the wires and there is no recurring cost to a service provider. The campus network topology is primarily LAN technology connecting all the end systems within the building.
Examples include circuit switched telephone lines, radio wave transmission, and optical fiber. Gigabit Ethernet provides high-bandwidth capacity for backbone designs while providing backward compatibility for installed media. Multilayer switches that provide Layer 2 and 3 functionality, for example, are now appearing in the marketplace.
WANs are often built using leased lines. LAN switches provide this performance benefit by increasing bandwidth and throughput for workgroups and local servers. Although individual purchase decisions might seem harmless, network designers must not forget that this separate equipment still works together to form a network.
This could be to facilitate higher bandwidth applications or provide better functionality for users in the CAN. If this overall integration is not considered, the result can be networks that have a much higher risk of network outages, downtime, and congestion than ever before.
A campus is generally a portion of a company or the whole company that is constrained to a fixed geographic area, as shown in Figure ATM, however, offers high-bandwidth capacity.A wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance/place.
Wide area networks are often established with leased telecommunication circuits. I. Physical Network Design A. Network Topology Business Needs University of Maryland University College required a facility that will provide the tools students need to properly complete the required full time workload.
A recent expansion that includes a library, office space, computer labs and classrooms will provide this capability and enhance students 94%(). Designing WANs. WAN communication occurs between geographically separated areas.
In enterprise networks, WANs connect campuses. When a local end station wants to communicate with a remote end station (an end station located at a different site), information must be sent over one or more WAN links.

A WAN, also known as a Wide Area Network, is an essential part to bigger corporate networks most government networks and companies with multiple sites as well. A WAN, basically, is 2 or more LANs (Local Area Networks) stuck together and running as one big network over a big geographical area.
WAN Design 2 Abstract In this paper I will explain how and why ACME Manufacturing will benefit from a WAN with VOIP. ACME Manufacturing is a quickly growing company that currently has headquarters in Atlanta. The Headquarters in Atlanta houses corporate operations, administrative staff, marketing, and accounting.
