Data rate coordination in protected variable-rate links
First Claim
1. A method for communication, comprising:
- sending first data over a first communication link to a destination communication system at a first data rate, which can be varied;
sending second data, comprising at least a portion of the first data, over a second communication link, from the source communication system to the destination communication system at a second data rate, which can be varied;
dynamically setting respective first and second data rates of the first and second communication links; and
at the destination communication system, selectively extracting at least the portion of the first data from one of the first and second data.

Abstract
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.

25. A communication apparatus, comprising:
-
a source communication system, which is arranged to transmit first data over a first communication link at a first data rate, which can be varied, and to transmit second data, comprising at least a portion of the first data, over a second communication link at a second data rate, which can be varied; and a destination communication system, which is arranged to receive the first and second data and to selectively extract at least the portion of the first data from one of the first and second data, wherein one of the source and destination communication systems comprises a controller, which is arranged to dynamically set the first and second data rates in the first and second communication links. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
