Abstract: A computer-implemented method for providing data communication between two or more host systems is provided. The method comprises designating a first network as a primary network by updating a routing table, monitoring network connections on the first network channel and a second network channel, transmitting data on the first network channel according to the routing table, detecting termination of network connection on the first network channel, determining to transmit data traffic on the first network channel, modifying the routing table, transmitting data traffic on the second network channel according to the routing table, detecting connection on the first network channel, and in response to the detection of data traffic on the first network channel, measuring a network attribute and comparing against a satisfactory threshold, and selecting the first network channel for data communication if the network attribute value satisfies the threshold.

Abstract: Aspects of the invention relate to systems and methods of providing voice communications over a packet switched network having one or more client device connected on a low bandwidth connection. One aspect allows VOIP connections to adapt to the various, and potentially changing conditions, caused by different connection types and transmission qualities. One aspect modifies the data, the encryption methods, the sampling frequencies, and other parameters of the VOIP configuration to improve the functioning of the VOIP communication. These parameters may be changed based on the connection types and transmission quality of both the sending and receiving devices, among other factors. Another aspect of the present invention relates to methods of predictive voice transmission by constantly recording into a buffer and only transmitting portions of the buffered recording based on the presence of voice.
