Patent ID: 7929972

Claim:
A method of transmitting data across a communications network having multiple channels, comprising: selecting a maximum or a minimum bandwidth for establishing a bandwidth for transmission of said data based on a priority status of said data, wherein a maximum bandwidth is selected for a given data rate if said data is priority data and a minimum bandwidth is selected for a given data rate if said data is not priority data; selecting a modulation scheme and symbol rate from available combinations of data rates and modulation schemes for said bandwidth, wherein said selecting is a function of said establishing said bandwidth; concluding if at least one channel from said multiple channels provides said bandwidth; if said bandwidth is not available for transmission, determining if said bandwidth is a minimum required bandwidth for transmitting said data; transmitting said data over said at least one channel when concluding said bandwidth is available or after said determining said bandwidth is said minimum required bandwidth; and if said bandwidth is not said minimum required bandwidth, modifying said symbol rate when said data is priority data, and when said data is not priority data and said modulation scheme is not BPSK, modifying said modulation scheme.
