a covered passageway specifically : a horizontal passageway through or under an obstruction. b : a subterranean gallery (as in a mine) c : burrow. 2 : a hollow conduit or recess : tube, well. tunnel.There are three basic types of tunnel construction in common use. Cut-and-cover tunnels are constructed in a shallow trench and then covered over. Bored tunnels are constructed in situ, without removing the ground above. Finally, a tube can be sunk into a body of water, which is called an immersed tunnel.In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another, by exploiting encapsulation. It involves allowing private network communications to be sent across a public network (such as the Internet) through a process called encapsulation.
