Abstract
The present invention is directed to data communication. In certain embodiments, the present invention provides switching mechanism for choosing between redundant communication links. Data received from a first set of communication links are processed to have alignment markers removed, and first figure of merit value is determined based on the data without alignment markers. Similarly, a second figure of merit value is determined for the data received from the second set of communication links. A switch selects between the first set of communication links and the second set of communication links based on their respective figure of merit values. Alignment markers are inserted into the data transmitted through the selected set of data links. There are other embodiments as well.
