Abstract: A method and system for using low earth orbit satellites to overcome latency is presented. In one embodiment, the method may include establishing a data session using a first channel having a first characteristic different than a second characteristic of a second channel, wherein the first channel is a Low Earth Orit (LEO) channel and wherein the second channel is a Geosynchronous Equatorial Orbit (GEO) channel; determining a type of traffic involved in the data session; determining whether the second channel should be used for the data session; when the second channel should be used for the data session, then switching the data session from the first channel to the second channel; and periodically monitoring the data session to determine whether the second channel should continue to be used for the data session.
