Abstract: The present application provides a method for dynamically allocating resources in an SDN/NFV network based on load balancing. For multimedia services with different demands, a virtual link mapping target, a constraint and a load state of a physical link are associated. A subtask is adaptively mapped to a network node according to the load state of the physical link. The method effectively distinguishes used resources and remaining resources of a physical node and a link to balance the load, and thereby improve the utilization of network resources and avoid occurrence of a local optimum or current optimum. The solution involves performing a subtask mapping to find a server node satisfying constraints for each subtask in a service request. The model for mapping the subtask is min T ? V ? ? Target 1 s . t . ? C 1 , C 2 , C 3 , C 4 .

Abstract: Audio and video devices can be virtualized using synchronous A/V streaming. When a video device such as a webcam is connected to a client terminal while the client terminal has established a remote session on a server, video data generated by the video device can be encoded into an encoded video stream using the H.264 or similar standard. Additionally, audio data corresponding to the video data can be embedded into the encoded video stream. The encoded video stream with the embedded audio can then be transferred to the server. The server-side components can extract the audio from the stream and perform the necessary decoding on the video and possibly on the audio data prior to providing the decoded data to drivers that function as virtualized audio and video devices on the server.

Abstract: A network device has a processor that executes software instructions for a primary control plane operable to program a primary data plane that processes packets received at the network device to determine how or whether the packets are to be directed into a network. The processor also executes software instructions for a secondary control plane operable to program a secondary data plane. The secondary control and data planes are software containerized versions of the primary control and data planes, respectively. One or more configuration changes to be made to the network device are received at the secondary control plane. Test packets are obtained from the primary data plane, and network processing decisions are executed by the secondary data plane on the test packets based on the one or more configuration changes. Results of the network processing decisions executed by the secondary data plane on the test packets are evaluated.

Abstract: The global proliferation of high speed communication networks has created unprecedented opportunities for geographically distributed resource interaction. However, while the opportunities exist and continue to grow, the realization of those opportunities has fallen behind. A dynamic process execution architecture solves the enormous technical challenges of providing effective and efficient process execution environments for geographically distributed resources to execute a complex project.

Abstract: Described are system, apparatus, article of manufacture, method, or computer program product embodiments for controlling streaming of media content. An embodiment operates by halting a presentation of future content from a buffer upon determining that the buffer is exhausted of content to present. The embodiment includes receiving one or more packets over a network connection, the one or more packets including media information corresponding to a first portion of streaming media content, in which the first portion corresponds to a second portion of the streaming media content. The one or more packets in a buffer are stored as buffered content. Responsive to determining that the network connection is not experiencing a burst condition, the buffer is trimmed. Then, presentation of buffered content is resumed and the first portion is caused to be presented in sync with the second portion.

Abstract: Embodiments presented herein describe techniques for tracking operators of a distributed computing environment (e.g., a streams processing environment) using metadata. During execution of a distributed application of the computing environment, a tracker tool monitors a plurality of operators of the distributed application. Each of the operators stores one or more specified metadata values associated with the operator. For each operator, the tracker tool retrieves the one or more specified metadata values associated with the operator. Upon determining that one of the one or more specified metadata values do not comply with a corresponding expected metadata value, the tracker tool generates an indicator for the operator. The indicator includes information describing the one or more specified metadata values.
