In computer networks, a tunneling protocol is a communication protocol which allows for the movement of data from one network to another. They can, for example, allow private network communications to be sent across a public network (such as the Internet), or for one network protocol to be carried over an incompatible network, through a process called encapsulation.
Quantum tunneling, the quantum-mechanical effect where a particle crosses through a classically forbidden potential energy barrier; Tunneling (fraud), a fraud committed by a company's own management or by major shareholders; Tunneling protocol, transmitting one computer network protocol that is encapsulated inside another network protocol
Quantum tunneling oscillations of probability in an integrable double well of potential, seen in phase space. The concept of quantum tunneling can be extended to situations where there exists a quantum transport between regions that are classically not connected even if there is no associated potential barrier.
HTTP tunneling is used to create a network link between two computers in conditions of restricted network connectivity including firewalls, NATs and ACLs, among other restrictions. The tunnel is created by an intermediary called a proxy server which is usually located in a DMZ .
This was solved by IP tunneling. The first approach to IP tunneling used an IP Loose Source Route and Record (LSRR) Option to hide the multicast address from the non-multicast aware routers. A multicast-aware destination router would remove the LSRR option from the packet and restore the multicast IP address to the packet's IP destination field.
ICMP tunneling works by injecting arbitrary data into an echo packet sent to a remote computer. The remote computer replies in the same manner, injecting an answer into another ICMP packet and sending it back. The client performs all communication using ICMP echo request packets, while the proxy uses echo reply packets.
In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It uses encryption ('hiding') only for its own control messages (using an optional pre-shared secret), and does not provide any encryption or confidentiality of content ...
Tunneling or tunnelling is financial fraud committed by "the transfer of assets and profits out of firms for the benefit of those who control them". [1] In legal terms, this is known as a fraudulent transfer , such as when a group of major shareholders or the management of a publicly-traded company orders that company to sell off its assets to ...
