Types of WAN Connections
What is the types of WAN connections?
There are two main types of WAN connections.
- Dedicated Connection
- Switched 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.
- Circuit Switched Network.
- Packet Switched Network.
- 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.
