METHOD AND APPARATUS FOR PACKET RETRANSMISSION IN DSL SYSTEMS

摘要

Embodiments disclosed herein include systems and methods of packet retransmission. More specifically, at least one nonlimiting example of a method includes receiving data from above a y (gamma) interface, the data being identified as protected or not protected data; and storing the protected fragment in a retransmission queue included in a transport protocol specific transmission convergence layer.

主权项

1. A method, comprising:
receiving data at a physical medium specific transmission convergence layer; determining whether there is an error in the received data; in response to a determination that the received data includes the error, determining whether the error can be corrected with a forward error correction (FEC) decoder; in response to a determination that the error cannot be corrected with the forward error correction decoder, constructing an indication to a far-end transmitter device for retransmitting at least a portion of the data received in error; and in response to a determination that the data includes no error or the error can be corrected with the forward error correction decoder, sending the data across an α/β (alpha/beta) interface for rescheduling in a transport protocol specific transmission convergence layer.
