Abstract: At least one retransmission request is received from each of a plurality of wireless devices receiving a multicast broadcast, and a number of retransmission requests received from each of the plurality of wireless devices is determined. A first group of wireless devices is selected from among the plurality of wireless devices, and a delay time is determined for each wireless device in the first group based on the respective number of retransmission requests from each wireless device. When a data packet is not received at the one or more wireless devices of the first group, a timer is started at each of the wireless devices of the first group using the respective delay times. When the shortest delay time expires, another retransmission request is received from the wireless device comprising the shortest delay time of the one or more wireless devices.

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: In one embodiment, an ingress device of a first routing domain in a computer network buffers received packets, and in response to receiving a request from a particular node indicating that the particular node has migrated from the first routing domain to a second routing domain, determines how to reach the particular node in the second routing domain, and forwards the buffered received packets to the particular node in the second routing domain, accordingly. In another embodiment, a device in the first routing domain migrates from the first routing domain to a second routing domain, and determines its new IP address. The device may then send a request to the first ingress router to forward buffered packets for the device to the second routing domain at the new IP address, and may thus receive buffered packets forwarded from the first ingress router at the device in the second routing domain.

The authentication request message is forwarded from the PN gateway to one or more PNEs mapped to the ID information of the PN, with reference to a PN routing table in which information about the one or more PNEs is mapped to the ID information of the PN. The one or more PNEs receive a service from the server through the PN gateway.

Abstract: An alternate path calculation process may be terminated after considering some of a source node's neighbors and without considering each of its neighbors, to reduce the amount of processing required to perform the alternate path calculations. The neighbors may be ranked according to the number of alternate paths that the neighbor has historically been able to provide on the network. The influence of historical success or failure may degrade over time so that the rankings may be adjusted to reflect changes in network topography. A given source node, when computing alternate paths through the network, may preferentially select neighbors to perform alternate path calculations on historically higher scoring nodes before performing calculations on historically lower scoring nodes. Several different criteria may be used to stop the alternate path calculation process before considering all neighbors. The neighbors may be loop free neighbors or U-turn neighbors.

Abstract: A multi-mode congestion control is employed in a transport network interconnecting a radio access node and a control node of a communication network. The transport network employs a window-based state providing a window-based congestion control mode for a data flow. This mode involves notifying an application level transport protocol implemented in a sending source of the communication network of any detected congestion event. If a congestion event in the transport network is detected a switch to a rate-based state is performed. The rate-based state provides a rate-based congestion control mode involving transmitting a rate-reducing message from the radio access node to the control node to trigger a reduction in the bitrate of the data flow in response to the detected congestion event.
