摘要： A streams manager determines when congestion is happening or is predicted to happen in a streaming application, and in response, unfuses one or more operators in the streaming application from its processing element. The selection of which operators to unfuse in which processing elements is made using suitable unfuse criteria, which may include selecting operators that do not maintain state, selecting operators that have a threaded port or queue preceding the operator, selecting operators at natural boundaries, and inserting queues before operators to be unfused. Once one or more operators are unfused, the streams manager can take action to enhance performance of the unfused operator(s). For example, the streams manager can allocate additional resources to the unfused operators, can create clones of unfused operators that process tuples in parallel, can move one or more unfused operators to a public cloud, etc.

摘要： Example embodiments described herein provide systems and methods for transmitting data packets between a protocol sender and a protocol receiver in a cloud environment, having either the protocol sender or the protocol receiver residing within a virtualized host. A protocol acceleration module may observe the data packets transmitted along the data path between the protocol sender and the protocol receiver using protocol stack configuration information of the protocol sender. The protocol acceleration module may override the protocol stack configuration information with policy-based protocol stack configuration information such that data packets transmitted from the protocol acceleration module to the protocol receiver use the policy-based protocol stack configuration information. For various embodiments, the protocol stack configuration information of the protocol sender is not modified.

摘要： Conventional quality of service (QoS) treatment is extended to over-the-top (OTT) applications transmitting data over a commercial wireless network via a virtual private network (VPN) tunnel. An over-the-top (OTT) application server and a VPN client/server routing data to/from that OTT application server via a VPN tunnel, are integrated with a quality of service (QoS) server to enable the OTT application server and/or VPN client/server to request and get desired QoS treatment for application data routed by the OTT application server over the VPN tunnel. The QoS server forwards QoS rules received in a QoS request message to a policy and charging rules function (PCRF) on the OTT application/VPN client devices' home mobile network operator (MNO). If the client device is roaming, the PCRF on the home MNO forwards QoS rules to a PCRF on a serving MNO. QoS treatment is then carried out by the PCRF in a conventional manner.

摘要： A method is provided in one example embodiment and includes receiving at a network element a flow offload decision for a first service node that includes a portion of a service chain for processing a flow; recording the flow offload decision against the first service node at the network element; and propagating the flow offload decision backward on a service path to which the flow belongs if the first service node is hosted at the network element. Embodiments may also include propagating the flow offload decision backward on a service path to which the flow belongs if the flow offload decision is a propagated flow offload decision and the network element hosts a second service node that immediately precedes the service node on behalf of which the propagated flow offload decision was received and a flow offload decision has already been received by the network element from the second service node.

摘要： Disclosed herein are various systems and methods that may improve the transmission of data over low-bandwidth communication channels in an electric power delivery system. Devices communicating across a low-bandwidth communication channel may implement several approaches, according to various embodiments disclosed herein, to reduce the data transmitted across the low-bandwidth communication channel and to prioritize the transmission of time-sensitive and/or more important information with respect to other data. Various embodiments disclosed herein may inspect packets to be transmitted across a low-bandwidth communication channel in order to identify high priority data. High priority data may be time-sensitive information, and accordingly, transmission of such data may be prioritized over other data in order to reduce transmission latency of the higher priority data.

摘要： A system, method, base station, and computer program product for coordinating communication of data packets between a user device and an application server is described. The data packets may correspond to a bit-stream of encoded video data. In one aspect, the base station includes a memory and a computer processor operatively coupled to the memory, to a radio transmitter, and to a radio receiver. The processor is configured to detect a video frame type of the data packets and transmit one or more of the plurality of data packets based on the detected video frame type. For example, the processor may transrate, drop, or schedule the data packet for transmission based on the detected video frame type.
