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: A method of providing video content is disclosed that includes receiving video content associated with a television stream from a video source at a server of a video distribution network. The method also includes sending a primary multicast video stream corresponding to the video content to a video distribution network entity via an Internet Protocol (IP) network. The primary multicast video stream is associated with a first bandwidth. Further, the method includes sending a secondary multicast video stream to the video distribution network entity via the IP network. The secondary multicast video stream is associated with a second bandwidth. The primary multicast video stream and the secondary multicast video stream are accessible to a set-top box device via the video distribution network entity in response to a channel change request that indicates the television stream.

Abstract: An application provisioning device may be used to manage a profile of a host and provide data corresponding to a selected application for installation at a host. A reverse firewall may use the profile of the host to determine whether to allow or block particular network communication from an application running on the host. An indication of a selected application may be received at the application provisioning device. Configuration information may also be received at the application provisioning device. The application provisioning server may request an update to the profile of a host and transmit such a request. The profile may be updated to reflect the configuration information and/or information of the selected application. Data corresponding to the selected application may be updated and transmitted to a host computer, where it may be installed. Therefore, the installed application running on the host may operate without being prematurely blocked by the reverse firewall.

Abstract: A system that incorporates teachings of the present disclosure may include, for example, a controller to determine a behavioral profile of an end user from packet traffic generated by activities of the end user, and share the behavioral profile with a network element for distributing targeted advertisements to the end user according to the behavioral profile. Additional embodiments are disclosed.

Abstract: A method of configuring a network access device connected to an access network connected to a plurality of service networks, the network device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a second subscriber of services of either the first service provider, or a second service provider provided by a second service network. The method comprises the steps of: sending a request from the network access device to the access network with user credentials for the second subscriber requesting access to the first service provider or a change to the second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol.
