What is WAN design?

What is WAN design?

WAN links are connected by switches, which are devices that relay information through the WAN and dictate the service provided by the WAN. WAN communication is often called a service because the network provider often charges users for the services provided by the WAN (called tariffs).

What are WAN design objectives?

The objective of WAN is to transport the data over the large networks with the help of ISPs and Telco’s. We use the different devices, protocols, application and technologies like ATM, ISDN and frame-relay etc. for communication among our distant offices.

What are two common WAN Wide Area Network design types?

There are several types of network topologies that are used in networking systems. However, the ones that are most commonly used for WAN purpose are Dual ring and mesh topologies.

What is an example of wide area network?

WAN, the popular word in network, refer to wide area network, is a network which is used to connect different local area networks (LAN). There may be used many router to connect large amount of LANs. The big example of wide area network is internet. On internet we transfer files from one computer to other.

What is LAN architecture?

LAN architecture is the set of rules and design principles that define the LAN. A LAN is made up of three components: physical media, such as the cabling and network interfaces; the topology, such as a star or ring topology; and the protocols, or LAN technologies, such as Token Ring or Ethernet.

What is the media of WAN?

A WAN is a network that uses various links—private lines, Multiprotocol Label Switching (MPLS), virtual private networks (VPNs), wireless (cellular), the Internet—to connect smaller metropolitan and campus networks in diverse locations into a single, distributed network.

What are the components of a wide area network?

WAN consists of different components that combine together to form a wide area network.

• Routers, Switches and Modems (Edge Device)
• Connecting Media (Fiber, Wireless, Microwave or Satellite)
• Customer Premises Equipment (CPE)

How does a wide area network work?

What are the key features of a wide area network?

WANs have a large capacity,connecting a large number of computers over a large area,and are inherently scalable.

They facilitate the sharing of regional resources.

They provide uplinks for connecting LANs and MANs to the Internet.

What are the examples of wide area network?

ATM: A dedicated-connection switching technology that organizes digital data into 53-byte cell units.

Frame Relay: (FR).

SONET/SDH: Synchronous Optical Network is an international standard for high speed communication over fiber-optic networks.

What are the disadvantages of a wide area network?

Many Skilled technicians and network administrators are required to handle the network servers.

There is no guarantee in the privacy of the users. It is easy to access the information for a third party.

A good firewall is required to restrict third party users from accessing the data.

Providing security to users is a little complex.

What does wide area network stand for?

Wide area network. A wide area network is a network that covers a broad area using private or public network transports.
