Abstract: A wireless transmitter transmits a plurality of data blocks defined in a transmission window for receipt by a receiver. The transmitter transmits a status request to the receiver for positive acknowledgement of successful receipt of the status request, the status request identifying a data block. The transmitter updates the transmission window upon receipt of a positive acknowledgement of receipt of a data block or upon receipt of a positive acknowledgement of receipt of a status request relating to a data block. The updating removes the record of the data block from the transmission window and adds a record of at least one different data block to the transmission window.

Abstract: The present invention relates to a method and a transmitting unit for reducing a risk of transmission stalling between a transmitting unit and a receiving unit in a communication network system comprising said transmitting unit arranged to transmit data blocks to said receiving unit. Each data block comprises a block sequence number and transmitted data blocks are stored in a transmission buffer. A transmission buffer window is arranged to control the flow of retransmission of said transmitted data blocks. When the block sequence number has been acknowledged in a piggybacked acknowledgement/negative acknowledgement field, it is only set as acknowledged upon receipt of a packet uplink acknowledgement/negative acknowledgement message or a packet downlink acknowledgement/negative acknowledgement message comprising an acknowledgement for said block sequence number.

Abstract: A network stack includes a packet loss analyzer that distinguishes between packet losses due to congestion and due to lossyness of network connections. The loss analyzer observes the packet loss patterns for comparison with a packet loss model. The packet loss model may be based on a Forward Error Correction (FEC) system. The loss analyzer determines if lost packets could have been recovered by a receiving network device, if FEC had been used. If the lost packets could have been corrected by FEC, the loss analyzer assumes that no network congestion exists and that the packet loss comes from the lossy aspects of the network, such as radio interference for wireless networks. If the loss analyzer determines that some of the lost packet could not have been recovered by the receiving network device, the loss analyzer assumes that network congestion causes these packet losses and reduces the data rate.

Abstract translation: 网络堆栈包括分组丢失分析器，其区分由于拥塞引起的分组丢失以及由于网络连接的有损性。 损耗分析仪观察丢包模式，以便与丢包模型进行比较。 分组丢失模型可以基于前向纠错（FEC）系统。 如果使用了FEC，丢失分析器将确定丢失的数据包是否已被接收网络设备恢复。 如果丢失的分组可能被FEC纠正，则丢失分析器假设没有网络拥塞，并且分组丢失来自网络的有损方面，例如无线网络的无线电干扰。 如果丢失分析器确定某些丢失的分组不能被接收网络设备恢复，则丢失分析器假设网络拥塞导致这些分组丢失并降低数据速率。

Abstract: Embodiments of the present disclosure allow a HARQ transmitter to provide a receiver an indication of the protocol data units (PDUs) that should not be expected because they are part of a data burst that has been retransmitted a maximum allowable number of times. The indication message may contain a maximum serial number contained in the data burst that has reached the maximum number of retransmissions, or the serial number of a first PDU in the next data burst.

Abstract: Systems are provided for sequencing, delivery acknowledgement, and throttling of data packets over a network layer, such as UDP and SMS. To support devices with limited battery resources, the invention incorporates asymmetric retry logic and/or acknowledgements with overlapping ranges, to minimize the transmissions required for the device. The sender of a data-bearing frame does not need to wait for a frame to be acknowledged before sending the next, such that many frames can be “in flight” at once.

Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for adaptive data unit transmission. A sliding window is filled with data units and designates a sliding window start position and a sliding window end position. A value for each of the data units in the sliding window is stored, the value representing a maximum number of times that each data unit is to be transmitted. The stored value is different among at least two of the data units. Data units are selected from the sliding window to be assembled into a packet. An assembled packet is transmitted to a receiving computerized device. A determination that the data unit positioned at the sliding window start position has been transmitted a maximum number of time is performed, and in response a different data unit is positioned at the sliding window start position.

Abstract: Providing transport protocol within a communication network having a lossy link. The receiver distinguishes between packets received with non-congestion bit errors and packets having been not at all received due to congestion. When packets are received with non-congestion bit errors, the receiver sends selective acknowledgments indicating that the packets were received with bit errors while suppressing duplicate acknowledgments to prevent the invocation of a congestion mechanism.

Abstract: A router is operative to perform the following actions for each one of a plurality of wireless mobile devices operating in a wireless network. The router transmits to the wireless mobile device a number of data packets matched for a window size. The router changes the window size for the wireless mobile device based on whether a round trip time for communicating the data packets is within a threshold value. The router will update the threshold value based on the round trip times associated with traffic communicated via the router for all of the wireless mobile devices.
