Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for encoding frameless packets. One of the methods includes receiving a data payload to be transmitted. The data payload is partitioned into multiple payload words, each payload word being of a predetermined size. A first sync word is added to each of the multiple payload words. A control word comprising label and an error checking value is added. A second sync word is added to the label and error checking word. If one or more counter criteria are satisfied while transmitting the multiple payload words, an idle word is transmitted before transmitting the label and error checking word.
