摘要： Embodiments are directed towards managing communication over a network assist application classification using predicted subscriber behavior. Subscriber information associated with a network flow may be determined. Prediction information that includes application identifiers may be generated based on the subscriber information. A classification engine may determine the applications associated with the network flow based on the prediction information and the network flow using a plurality of application classifiers that correspond to the applications. If an application identifier included in the prediction information is correspondent to an application classifier, the application may be determined based on the correspondent application classifier; otherwise the application is determined based on the remainder of the application classifiers. A policy for managing the network flow may be determined based on the determined application. Then the network traffic associated with the network flow may be communicated based on the at least one determined policy.

摘要： The present invention relates to congestion control for acknowledged communication over networks. The congestion is detected on the basis of the trends of both the flight size and the transmission rate in order to adapt the congestion window in accordance with the detection result. Such congestion detection enables, for instance, distinguishing between the congestion with or without unfair competition. Moreover, the measured transmission rate or its trend is filtered to compensate for time variations. The invention may be embodied within an end node or within a proxy.

摘要： The present invention includes various novel systems and methods for communication in a network. A System Environment Monitor is employed in some embodiments to extract from the network both real-time and historical Network Metrics at the Infrastructure Layer, as well as Application Metadata at the Application Layer. Network analytics facilitate decisions based upon the differing characteristics of Application Components and lower-level hardware components across multiple DTTs. In response, an SDN Controller generates modified sets of SDN Flows, and implements them in real time across a mixed technology (multi-DTT) network in a manner that avoids disrupting existing SDN Flows and other real-time network traffic.

摘要： A method for localized congestion exposure within a local loop in a cellular network that is performed by a localized congestion exposure receiver node of the local loop. The method includes receiving downlink packets destined for a downstream user device. The downlink packets have headers that indicate a level of congestion experienced by the downlink packets. The headers also indicate a level of expected downstream congestion declared by an upstream node. The method also includes forwarding the downlink packets to the downstream user device through a wireless connection. The method further includes sending packets upstream that have feedback indicative of the level of congestion experienced by the downlink packets and any congestion experienced within the localized congestion exposure receiver node.

摘要： In a packet communication system with large bandwidth delay product (BDP) and employing Transmission Control Protocol (TCP), the reported advertised window size as advertised by a receiver is employed only as an indication of window size and not as a throughput limit so that more data is sent than the amount specified by the advertised window size. Since the receiver can process all incoming TCP packets, the receiving buffer is consistently near empty. Since the TCP's advertised window size is not accepted as the absolute amount of buffer space available at the receiver, the sender is not constrained by the absolute value of the receiver's advertised window size and instead can transmit more data than the absolute value of the advertised window, enabling the system to increase the actual window size without modifying the link ends. This improved large-BDP-capable protocol is denoted TCP-SC.
摘要翻译：在具有大带宽延迟产品（BDP）并采用传输控制协议（TCP）的分组通信系统中，由接收机通告的所报告的通告窗口大小仅用作窗口大小的指示而不是吞吐量限制，发送的数据超过广告窗口大小指定的数量。由于接收器可以处理所有传入的TCP数据包，因此接收缓冲区一直接近空。由于TCP的广告窗口大小不被接收为接收机可用的缓冲区空间的绝对量，所以发送方不受接收方通告的窗口大小的绝对值约束，而是可以传送比通告窗口的绝对值更多的数据，使系统能够增加实际的窗口大小，而无需修改链接结束。这种改进的具有大BDP能力的协议被表示为TCP-SC。
