Abstract:
1. A link selection method for bonded data transmission links, comprising: determining a link priority for first and second links in a bonding group comprising the bonded data transmission links, the first and second links being of different link types, the determined link priority for first and second links being based on a data transmission reliability of the first and second links, respectively; detecting a link-to-group backpressure of the first and second links, the link-to-group backpressure of the first link being detected based on a first link congestion status of the first link that indicates the availability of the first link to accept additional data, and the link-to-group backpressure of the second link being detected based on a second link congestion status of the second link that indicates the availability of the second link to accept additional data; and selecting one of the first and second links as a next link to be used for data transmission based on the determined link priorities and the detected link-to-group backpressures of the first and second links, wherein the first link congestion status indicates that the first link is unavailable to accept additional data when a detected fill level in a first first-in-first-out (FIFO) memory provided in the first link exceeds a first watermark of the first FIFO and wherein the first link congestion status indicates that the first link is available to accept additional data when the detected fill level in the first FIFO is below a second watermark of the first FIFO.
