Abstract
Embodiments disclosed herein are configured for retransmission above the gamma (γ) interface. At least one embodiment of a method includes receiving data from an Ethernet layer, the data being identified as eligible for retransmission or not eligible for retransmission; in response to a determination that the data is eligible for retransmission, storing a copy of at least a portion of the data in a retransmission queue; and transmitting the data across a gamma (γ) interface to a packet transfer mode transmission convergence layer.
Claims19
A retransmission method, comprising:
- receiving data from an Ethernet layer, the data being identified as eligible for retransmission or not eligible for retransmission;
- in response to a determination that the data is eligible for retransmission, storing a copy of at least a portion of the data in a retransmission queue;
- and
- transmitting the data across a gamma (Υ) interface to a packet transfer mode transmission convergence layer.
A retransmission system, comprising:
- a demultiplexor configured to receive data from a transmitter device across a gamma (Υ) interface, the demultiplexor configured to determine whether the received data is at least one of the following:
- eligible for retransmission, not eligible for retransmission, and retransmitted;
- and
- a retransmission buffer coupled to the demultiplexor, the retransmission buffer configured to, in response to a determination that the received data is eligible for retransmission, determine whether the received data has at least one uncorrectable error or is missing at least one DTU because of a detected gap in received sequence identifiers of correctly received DTUs and, in response to a determination that the data includes at least one uncorrectable error or is missing at least one DTU because of a detected gap in received sequence identifiers of correctly received DTUs, send a retransmission request across the gamma (Υ) interface to the transmitter device to facilitate retransmission of at least a portion of the data,
- the retransmission buffer further configured to, in response to a determination that the received data is retransmitted data, recombine the retransmitted data with stored data for sending to a reassembly block.
A retransmission system, comprising:
- an identifying block configured to receive data from an Ethernet layer, the identifying block configured to determine whether the received data is eligible for retransmission or not eligible for retransmission;
- a retransmission buffer configured to, in response to a determination that the data is eligible for retransmission, storing at least a portion of the data;
- and a transmitting component configured to transmit the received data across a gamma (Υ) interface to a packet transfer mode transmission convergence layer.
