A method for communication includes sending first data over a first communication link to a destination communication system at a first data rate, which can be varied. Second data, including at least a portion of the first data, is sent over a second communication link from the source communication system to the destination communication system at a second data rate, which can be varied. First and second data rates of the respective first and second communication links are dynamically set. At least the portion of the first data is selectively extracted from one of the first and second data at the destination communication system. In some embodiments, the first data equals the second data, and the data is extracted without data loss.

Data rate coordination in protected variable-rate links

A method for communication over a communication link, which includes a transmitter and a receiver, includes transmitting and receiving data, which is encoded using a specified forward error correction (FEC) code, modulated using a specified modulation scheme and transmitted at a given power level. One or more parameters of the communication link are monitored. A condition, which is based on values of one or more of the parameters monitored at a plurality of historical time instants, is evaluated. At least one feature of the transmitted data, selected from a group of features consisting of the FEC code, the modulation scheme and the power level, is modified based on the condition.

Adaptive coding and modulation based on link performance prediction

A communication system includes a first communication unit, which is arranged to communicate with a remote communication system over a first communication link having a first, variable data rate. A second communication unit is arranged to exchange data with the remote communication system by communicating with the first communication unit over a second communication link having a second data rate. The first and second communication units are arranged to modify the second data rate responsively to variations in the first data rate, so as to match the second data rate to the first data rate.
