selectively disabling mechanisms reliable network connection

One or more computer readable media having computer-executable instructions embedded therein that, when executed, they perform a method of communicating through a network connection established between a first endpoint and a second endpoint residing in networks disparate, the method comprising: providing (602) the network connection extending between the first endpoint and the second endpoint, wherein the network connection operates as a tunnel bridging the disparate networks in which they reside the first endpoint and the second endpoint, respectively, in which communication messages between the first endpoint and the second endpoint comprises packet transmission Internet protocol, IP, from the first endpoint to the second endpoint through tunnel, wherein the network connection includes a connection running higher level above the lower level connection, where s and integrally execute one or more mechanisms reliability higher level in connecting upper level and integrally execute one or more mechanisms reliability of the lower level in the lower level connection, wherein the one or more reliability mechanisms the lower level comprises a control mechanism configured to manage congestion transmission rate IP packet; disabling (604) selectively one or more mechanisms reliability of the lower level, being performed automatically disabling unless an input in the opposite direction is provided, wherein the control mechanism congestion built into the lower level connection is disabled for the first endpoint without any negotiations with the second end when the first end acts as the transmission end; and communicating (606) messages between the first endpoint and the second endpoint through the tunnel.
