    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: An apparatus is provided in one example embodiment and it includes a first node coupled to an active endpoint and a standby endpoint. The first node communicates with a second node. When the active endpoint experiences a failure, the standby endpoint is activated such that a communication involving the second node continues. The standby endpoint communicates a complete window's worth of packets to the second node after the failure, the window's worth of packets including a last known sequence number acknowledged by the second node. In more specific embodiments, the first node is an L2TP network server (LNS) and the second node is an L2TP access concentrator (LAC). The last known sequence number was check pointed by the active endpoint to the standby endpoint.

    Abstract: A method for detecting unavailable network connections comprises, at a first data processing node that is hosting a transport protocol connection that uses a plurality of sequence values to identify messages sent to a peer node, wherein the first node is communicatively coupled to a second data processing node serving as a redundant backup, periodically sending a checkpoint sequence value to the second node; detecting that either the transport protocol connection or a process using the transport protocol connection is unavailable, without use of a timeout; and in response thereto, sending a notification to the peer node, wherein the notification includes the checkpoint sequence value. One embodiment provides for rapidly detecting and responding to failure of a TCP process without using long timeouts as conventionally provided in long-lived applications that run on top of TCP.

    Abstract: A router is operative to perform the following actions for each one of a plurality of wireless devices operating in a wireless network. The router initially transmits a number of data packets matched for a window size which corresponds to a default window size. The router then measures a round trip time (RTT) associated with communication of each of the transmitted packets. The router increases the window size if the RTT associated with the communication of each of the transmitted packets is within a first threshold. On the other hand, the router decreases the window size if the RTT associated with the communication of any of the transmitted packets is more than the first threshold but less than a second threshold. The router sets or updates at least one of the first or the second thresholds based on traffic communicated to the plurality of wireless devices via the router.

    Abstract translation: 路由器可操作以对在无线网络中操作的多个无线设备中的每一个执行以下动作。 路由器最初发送与对应于默认窗口大小的窗口大小匹配的数个数据包。 然后路由器测量与每个发送的分组的通信相关联的往返时间（RTT）。 如果与每个发送的分组的通信相关联的RTT处于第一阈值内，则路由器增加窗口大小。 另一方面，如果与任何发送的分组的通信相关联的RTT大于第一阈值但小于第二阈值，则路由器减小窗口大小。 路由器基于经由路由器传送到多个无线设备的业务来设置或更新第一或第二阈值中的至少一个。
