Abstract:
1. A method of implementing adaptive coding and modulation in a satellite communications network, the method comprising: associating a first modcode of a first order with a first signal quality range; associating a second modcode of a second order higher than the first order with a second signal quality range of better quality than the first signal quality range; receiving a first packet destined for a first link within the first signal quality range and a second packet destined for a second link within the second signal quality range; encapsulating the first packet in a payload portion of a first frame; determining that an available portion of the payload portion is insufficient to fit the second packet; fragmenting the second packet into a first fragment sized to fill the available portion and a second fragment; encapsulating the first fragment in the available portion of the payload of the first frame; and transmitting the payload portion of the first frame in the satellite communications network according to the first modcode.
