Establishing tunneling connection over restrictive networks

Abstract:

Systems, methods, and software can be used for establishing a tunneling connection over restrictive networks. One example of a method includes selecting, at an endpoint, at least one protocol to be used to establish a tunneling connection between the endpoint and a server. The at least one protocol is one of transmission control protocol (TCP) or user datagram protocol (UDP). The method further includes transmitting data between the endpoint and the server over the tunneling connection by using the selected at least one protocol.
