Abstract: Described herein are techniques optimizing queries on data in a data lake. The techniques involve ingesting data from multiple data lake sources, partitioning the data based on a key, and generating a partition index based on the key. The partition index can then be used to efficiently perform queries on data in the data lake.

Abstract: Systems, methods, and computer-readable media provide techniques for on-demand access to object data hosted in distributed object storage. A query is received for the distributed object storage database, wherein the distributed object storage database includes first object data stored in a first data center at a first geographical location, and second object data stored in a second data center at a second geographical location. It is determined that the query is for at least a portion of the first object data stored by the first data center. The query is transmitted to a first computing device in the first data center. Results are received from the first computing device for the query, and the results are provided in response to the received query.

Abstract: A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending, via a transmitter, a primary video stream corresponding to a particular channel to a media device. The operations further include sending a secondary video stream to the media device. The secondary video stream is associated with a lower quality level than the primary video stream. Transmission of a frame of the secondary video stream is delayed with respect to transmission of a corresponding frame of the primary video stream.

Abstract: Network resources for a call are allocated. The network resources for the call are reserved based on a reservation. The network resources are reserved before any one network resource is committed. If the call is confirmed, then the network resources are committed.

Abstract: A system includes a processor and a memory. The memory stores instructions that, when executed by the processor, cause the processor to perform operations including sending a primary multicast video stream and a secondary multicast video stream to a media device. The secondary multicast video stream is limited to intra-coded frames (I-frames) extracted from the primary multicast video stream. Transmission of each intra-coded frame (I-frame) of the secondary multicast video stream is delayed with respect to transmission of a corresponding I-frame of the primary multicast video stream. The delay is based on an amount of writing time to satisfy a buffer threshold of a video content buffer at the media device to prevent a noticeable time shift of video displayed by the media device when the media device switches from outputting the secondary multicast video stream to outputting the primary multicast video stream.

Abstract: Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. The network resources are reserved before any one network resource from the reserved network resources is committed. The reserved network resources for the call are committed when a called party indicates acceptance for the call.

Abstract: Lawfully-authorized electronic surveillance is performed. A call associated with a first party to be surveilled is verified, on a per-call basis. Packets associated with the call are sent to a second party. Copies of the packets are sent to a surveillance receiver.

Abstract: Method and apparatus for providing a control plane across multiple optical network domains is described. In one example, topology and resource discovery is employed in a transport network having a plurality of control domains. Topology information for each of the control domains is summarized to produce summarized topology information. The summarized topology information for each of the control domains is exchanged among the control domains. At each of the control domains, the summarized topology information of each of the control domains is combined to produce combined topology information. The combined topology information is passed among network elements within each of the control domains using an intra-domain routing protocol.
