This paper presents the designs for new multilayer open systems interconnect protocols that improve Internet data transmission within a hybrid communication network consisting of a geo-stationary earth orbit satellite and a terrestrial channel. These new designs span the transport, network, and data-link open systems interconnect layers and decrease the time required to transmit large data sets over a hybrid communication network compared to the Transmission Control Protocol variant Reno and frequency division multiplexing over a geo-stationary earth orbit satellite. This paper outlines the functional details for these news designs, provides simulated data transmission performance characteristics for all designs, and concludes with justifications for and benefits related to our research. 1 2
