1. A method for communication to a destination over multiple satellite links using different spectrums, respectively, comprising:
- using a plurality of bands for data communication in a single antenna dish and single router,measuring link performance parameters during the data communication, wherein data communication is permitted to the destination via a selected one of the bands in accordance with a comparison between the measured link performance parameters and predetermined criteria;
measuring the link performance parameters in real time;
storing the measured link performance parameters in the destination;
real time updating of the stored link performance parameters;
determining a link that serves as a guaranteed link for communication;
determining another alternative link, the guaranteed link have a lower throughput than the throughput of the another alternative link;
simultaneously establishing a plurality of physical connections over the satellite link(s) from the source to the destination; and
switching between the guaranteed and the another alternative links so as to uniquely establish a single IP link between the source to the destination at any given time.

Abstract
A satellite communication system between a source and a destination over multiple satellite communications paths including first identifying the link performance established in multiple spectrums, performing a link comparison among the multiple spectrums (for example C-, Ku-, or Ka-Band) in order to determine a spectrum link that provides the highest throughput within an acceptable reliability criteria, and switching among the multiple spectrum links to provide that determined spectrum link between the source and the destination.

12. A destination apparatus for receiving data over multiple satellite links using different spectrums, respectively, comprising:
-
a single antenna dish and single router that use a plurality of different bands for data communication over the different spectrums, and an intelligent modem for measuring link performance parameters during data communication, wherein the intelligent modem permits data communication via a selected one of the bands in accordance with a comparison between the measured link performance parameters and predetermined criteria; wherein the intelligent modem determines a link that serves as a guaranteed link to communication, and determines another alternative link, the guaranteed link having a lower throughput than a throughput of the another alternative link; and wherein the intelligent modem automatically switches between the guaranteed link and alternative link in accordance with the comparison between the measured link performance parameters and predetermined criteria;
simultaneously establishes a plurality of physical connections over the satellite link(s) from the source to the destination; and
switches between the guaranteed and the another alternative links so as to uniquely establish a single IP link between the source to the destination at any given time. - View Dependent Claims (13, 14, 15, 16)
