Abstract: A method is provides in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes (401) that a number of data units that has been transmitted by the sending node are missing. The receiving node sends (402) a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.

Abstract: Discussed is a method of sending status information (STATUS PDU) in which a receiving side reports a data received state to a transmitting side in a mobile telecommunication system. A receiving side RLC entity considers an available radio resource to construct a status PDU fit to the size of the radio resource and then sends the constructed status PDU to a transmitting side RLC entity, thereby avoiding a deadlock situation of RLC protocols.

Abstract: A communication system includes a plurality of nodes and a control device. Each node includes a packet processor that processes a packet in accordance with a processing rule when the packet is received. The processing rule correlates the processing applied to the packet with a matching rule that identifies the packet the processing is to be applied to. The control device calculates a packet forwarding path in response to a request for setting processing rules from any node, sets processing rules that implement the packet forwarding path on the node on the packet forwarding path and records the processing rules in a manner coordinated with one another. The control device inquires at the node on the packet forwarding path about state of setting of processing rule and, upon detecting failure in the processing rule set in at least one node, executes rollback operation on the correlated processing rules set in other node.

Abstract: Systems, methods, and devices for an improved recovery for the downlink are described herein. In some aspects, delay and overhead associated with retransmission of data lost due to an interruption can be reduced and/or eliminated by configuring a receiver to generate and transmit status information following resumption from the interruption. The receiver can be configured to generate and transmit status information immediately upon resuming from the interruption. In some aspects, the receiver can be configured to automatically generate and transmit status information independent of receiving a polling request from the sender. Status information can indentify at least last received user data prior to the interruption. In some aspects, status information further identifies lost data due to the interruption.

Abstract: A method and system for facilitating one-to-many data transmissions with reduced network overhead includes conducting a round of data transmissions from a source computing device to a plurality of sink computing devices. Each of the sink computing devices generates a bucket list of lost data blocks for the round of data transmissions and transmits the bucket list to the source computing device. The source computing device conducts a subsequent round of data transmissions based on the bucket lists. One or more additional subsequent rounds may be conducted until the bucket list of each sink computing device is empty.

Abstract: A method of transmitting data over a communication network using negative acknowledgment is presented. In the method, a stream of data packets is transmitted from a first node of the network to a second node of the network. All but at least two of the stream of data packets is successfully received at the second node, wherein the data packets that are not successfully received are not located sequentially within the stream of data packets. A status packet is transmitted from the second node to the first node, wherein the status packet includes an indication of each of the data packets that were not successfully received. In response to receiving the status packet at the first node, the data packets that were not successfully received at the second node are retransmitted from the first node to the second node in response to receiving the status packet.
