What Is Microtunneling?

For the construction of VPNs, network tunneling (Tunnelling) technology is a key technology. Network tunneling technology refers to the use of one network protocol to transmit another network protocol. It mainly uses the network tunnel protocol to achieve this function. Network tunneling technology involves three network protocols, namely the network tunneling protocol, the bearer protocol under the tunneling protocol, and the bearer protocol carried by the tunneling protocol.
