What are the types of WAN technologies?

Types of WAN technologies

  • TCP/IP protocol suite.
  • Router.
  • Overlay network.
  • Packet over SONET/SDH (PoS)
  • Multiprotocol Label Switching (MPLS)
  • ATM.
  • Frame Relay.

Which technologies are suitable for WAN connections over 50 Mbps?

SDH also provides 50 Mbps bandwidth at STM – 0. DWDM: DWDM stands for Dense Wavelength and Division Multiplexing and is a type of optical technology which is majorly introduced to further increase the bandwidth over fiber optic to overcome the requirements.

What are the key WAN technology concepts?

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 is DSL WAN technology?

DSL technology is an always-on connection technology that uses existing twisted-pair telephone lines to transport high-bandwidth data, and provides IP services to subscribers. A DSL modem converts an Ethernet signal from the user device to a DSL signal, which is transmitted to the central office.

What are the two types of WAN technology?

The two most common types of circuit-switched WAN technologies are the public switched telephone network (PSTN) and the Integrated Services Digital Network (ISDN).

Which WAN technology is best?

Here are 3 of the most secure WAN solutions:

  • MPLS. MPLS is a secure, reliable and flexible solution for nationwide WAN connectivity.
  • Metro Ethernet (MOE) Metro Ethernet Service is a flexible, easy-to-use, transport service that uses established Ethernet transport technology.
  • SD-WAN (Software Defined Network)

What is the best WAN technology to use?

Which technology is a private WAN technology?

The typical private WAN products are MPLS, VPLS, Short Haul Data Services, VLL (Virtual Leased Line) and Optical circuits. There are several different technologies available to decide upon when choosing how to build your organisation’s private wide area network (WAN).

What is a characteristic of a WAN?

It connects multiple networks that are geographically separated. It spans across a campus or city to enable sharing of regional resources. It is typically owned and managed by a single home or business. It requires a wireless access point to connect users to the network.

What does ADSL stand for?

Asymmetric Digital Subscriber Line
Asymmetric Digital Subscriber Line (ADSL) is a technology that provides high transmission speeds for video and voice to homes over an ordinary copper telephone wire.

Which of the following are examples of WAN technologies?

Most LANs today are Ethernet LANs. WANs are networks that span a larger geographic area and usually require the services of a common carrier. Examples of WAN technologies and protocols include Frame Relay, ATM, and DSL.

What are the different types of WAN technologies?

IPsec VPN securely connects all of your sites on the same private network using Internet connectivity as the data communications network. This type of VPN is deployed between a security appliance or firewall at each location, ensuring a secure IPsec tunnel between sites.

Which is the most expensive type of Wan?

Ethernet Private Line is available from 10 Mbps to 10Gbps, with 100Gbps available in some locations. EPL is one of the more expensive types of WAN technologies due to distance-sensitive pricing and dedicated network infrastructure used.

What are the advantages and disadvantages of a WAN?

Each has distinct advantages and disadvantages. Familiarity with these technologies is an important part of network design. As shown in Figure 1-17 and described in the list that follows, an enterprise can get WAN access in two ways.

What kind of Wan is needed for multiple sites?

If a private network connection between multiple sites is required, a point-to-point topology with multiple point-to-point circuits is one option. Each point-to-point circuit requires its own dedicated hardware interface that will require multiple routers with multiple WAN interface cards. This interface can be expensive.
