摘要： An application proxy is disposed between a user device and an application server. The application server supports an application that is available on the user device. The user device registers with the application proxy for the application. The user device is prevented from transmitting application update request messages to the application server. The application proxy transmits application update request messages to the application server on behalf of the user device. The application proxy receives application update response messages from the application server. The application proxy determines, based on the application update response messages from the application server, whether to send an application update notification message toward the user device. In this manner, application update traffic normally transmitted via the network between the user device and the application proxy is reduced. The application update request and response messages may be polling messages, keep-alive messages, and the like.

摘要： A capability is provided for reducing the effects of lost packets on algorithms used for reducing or eliminating redundant traffic in cellular wireless networks. An encoding node encodes a target packet using a reference packet from a packet cache of the encoding node, and transmits the encoded packet to a decoding node having a packet cache. The decoding node receives the encoded packet and attempts to decode the encoded packet to recover the target packet. The decoding node detects that the reference packet identified in the encoded packet is missing from the packet cache of the decoding node. The decoding node generates a control packet identifying the missing reference packet and transmits the control packet to the encoding node. The encoding node receives the control packet and processes the reference packet stored in the packet cache of the encoding node in a manner for preventing use of the reference packet, by the encoding node, for encoding packets for transmission to the decoding node.
摘要翻译：提供了一种能力，用于减少丢失数据包对用于减少或消除蜂窝无线网络中冗余流量的算法的影响。编码节点使用来自编码节点的分组高速缓存的参考分组对目标分组进行编码，并将编码分组发送到具有分组高速缓存的解码节点。解码节点接收编码的分组，并尝试对编码的分组进行解码以恢复目标分组。解码节点检测到编码分组中标识的参考分组从解码节点的分组高速缓存中丢失。解码节点生成识别丢失的参考分组的控制分组，并将控制分组发送到编码节点。编码节点以编码节点的方式接收控制分组并处理存储在编码节点的分组高速缓存中的参考分组，以防止使用参考分组来编码用于传输到解码节点的分组。

摘要： A system and method for latency assignment in a system having shared resources for performing jobs including computing a new resource price at each resource and sending the new resource price to a task controller in a task path that has at least one job running in the task path. A path price is computed for each task path of the task controller, if there is a critical time specified for the task. New deadlines are determined for the resources in a task path based on the resource price and the path price. The new deadlines are sent to the resources where the at least one job is running to improve system performance.
