Types of WAN Connections

Types of WAN Connections

What is the types of WAN connections?

There are two main types of WAN connections.

• Dedicated Connection 
• Switched Connection

Types of WAN connection

Dedicated Connections

In computer networks and telecommunications, a dedicated line is a communications medium or other facility dedicated to a specific application, in contrast with a shared resource such as the telephone network or the Internet is called dedicated connection.

1.Leased Lines:

• It is a dedicated point to point connection which provides pre-establish WAN communication path through ISP to remote destination is called as leased line.
• It provide very high speed data transmission up to 64Gbps.
• It is very expensive.

2.Digital Subscriber Line (DSL):

• It is a provide connection between ISP to a customer through telephone line.
• It is a broadband technique which provides same upstream and downstream.

3. Asymmetric Digital Subscriber Line (ADSL): 

• Asymmetric digital subscriber line is type of digital subscriber line technology a data communication technology that enables faster data transmission over the copper telephone line rather than conventional voice modem used. 
• It is some like as digital subscriber line but only difference is that upstream and downstream are different. 

Switched Connections

There are three types of switched connection are as follows.

1. Circuit Switched Network.
2. Packet Switched Network.
3. Cell Switched Network.

1. Circuit Switched Network:

• In circuit switches network every time before transferring data over the WAN, new connection get establish after data transfer over the connection get closed.
• In this technique generally data is transferred through single connection or single route.

2. Packet Switched Network:

• In packet switched network uses virtual connection for transferring data, it for transferring data create connection on first data transmission and used it as a permanent connection.
• It is faster than circuit switched network.
• It is used for multi path communication.

3. Cell Switched Network: 

• In this type of network data transfer in fixed size cell that is 53 bytes.
• Its example as ATM.
