20090089641 | RETRANSMISSION SCHEME FOR COMMUNICATION SYSTEMS - One embodiment relates to a method of communicating data between a transmitter and a receiver of a communication system. In this method, a payload data stream is received from a network interface layer. The payload data stream includes data units eligible for retransmission and data units non-eligible for retransmission. These data units are grouped into containers, where a container is associated with a container identifier that distinguishes the container from other containers. The containers are grouped into data transmission units, where a data transmission unit includes at least one container along with redundancy information that facilitates error detection for that data transmission unit. The data transmission units are transmitted to the receiver as a transmission data stream. Other methods and systems are also disclosed. | 04-02-2009 |
20090144590 | INTERLEAVING REDUNDANCY APPARATUS AND METHOD - One embodiment of the invention relates to a network communication device. The network communication device includes a network interface configured to receive an initial data stream. The network communication device also includes an interleaving redundancy encoder that comprises a memory unit arranged in N columns and D rows. The interleaving redundancy encoder is configured to calculate at least one redundancy byte based on a series of equally spaced, non-consecutive bytes in the initial data stream, where a number of bytes between equally spaced bytes is approximately equal to D−1. Other systems and methods are also disclosed. | 06-04-2009 |

20100046549 | Channel Bonding and Packet Fragment Retransmission Method and Apparatus - According to one embodiment, a physical line receiver is coupled to at least one of a plurality of bonded communication lines over which a sequence of packet fragments are transmitted as data units. The physical line receiver includes at least one physical sublayer that transfers packet fragments recovered from different ones of the data units received by the physical line receiver to a bonding sublayer for packet reassembly until the physical line receiver is instructed to stop transferring packet fragments because of a transmission error on one or more of the bonded communication lines coupled to a different physical line receiver. The at least one physical sublayer also buffers the recovered packet fragments without transferring the buffered packet fragments to the bonding sublayer until the physical line receiver is instructed to resume transferring packet fragments to the bonding sublayer. | 02-25-2010 |
20110072327 | Method and Device for retransmission - Embodiments related to retransmission in a communication system are described and depicted. In one embodiment, a retransmission entity repeats a transmission of a data transfer unit by the device after a predetermined number of other transmitted data transfer units has been transmitted. The retransmission entity may also determine whether a measure for a time period since the first transmission of the data transfer unit by the device has exceeded a predetermined threshold and to provide a final transmission of the data transfer unit based on the determining that the measure for the time period has exceeded the predetermined threshold. | 03-24-2011 |
