What switching technologies are mostly used in the WAN? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Most of the switching technologies used in WAN are packet switching.

Packet switching, also known as packet switching, divides the data communicated by users into a number of smaller equal-length data segments, and adds the necessary control information in front of each data segment as the head of the data segment, and each data segment with a header constitutes a packet.

The header indicates the address of the packet to be sent. When the switch receives the packet, it will forward the packet to the destination according to the address information in the header. This process is packet switching. A communication network capable of packet switching is called a packet switching network.

The essence of packet switching is store-and-forward, which temporarily stores the accepted packets and queues on the destination route. When it can send information, it sends the information to the corresponding route to complete forwarding. The process of storing and forwarding is the process of packet switching.
