Transport Frame Structure for Retransmission in DSL
First Claim
1. A method comprising:
- framing data into transport frames, each transport frame carrying payload data that is viewed differently according to the computing layer in which it is transported;
transporting the transport frames over a first computing layer, the payload data of each transport frame corresponding to an integer number Q of elementary cells of the first computing layer, an integer number of header bytes containing information specific to the transport frame, and an integer number of padding bytes; and
transporting the transport frames over a second computing layer, the payload data content of each transport frame corresponding to payload data of an integer number M of elementary cells of the second computing layer,wherein a number of padding bytes is determined such that a total number of bytes contained in the payload of the second computing layer M elementary cells equals a total number of bytes contained in the header bytes plus padding bytes plus Q elementary cells of the first computing layer.
