Disclosed are various embodiments for fragmentation of time-associated streaming data. A producer application receives a stream of time-associated data. The producer application then generates a first fragment of the stream of time-associated data and assigns a first unique fragment identifier and a first timestamp to the first fragment. The producer application sends the first fragment via a network using an application-layer protocol to an endpoint. The producer application receives at least one acknowledgement for the first fragment from the endpoint via the network using the application-layer protocol.

Fragmentation of time-associated data streams

Various embodiments replicate and index fragments of a stream of time-associated data. In one embodiment, a stream endpoint application receives a first fragment of a stream of time-associated data from a producer via a network using an application-layer protocol. The stream endpoint application determines a producer timestamp from the first fragment. The stream endpoint application sends at least one acknowledgment to the producer via the network using the application-layer protocol. The stream endpoint application indexes the first fragment and sends the first fragment to a destination.

Replicating and indexing fragments of time-associated data streams

Disclosed are various embodiments for a framework for time-associated data stream storage, processing, and replication. A plurality of streams of time-associated data are received from a plurality of sources via a network using an application-layer protocol. Each of the plurality of streams is divided into a plurality of fragments. An acknowledgement is sent to each of the plurality of sources for each of the plurality of fragments via the network using the application-layer protocol. Processing is performed on each of the plurality of fragments for individual ones of the plurality of streams. An action is implemented relative to a respective fragment based at least in part on a result of the processing.

Framework for time-associated data stream storage, processing, and replication

Methods and apparatus are described for partitioning a manifest file to generate smaller manifest files for media content playback. A server partitions a manifest file prior to receipt of a request from a client or in response to a request from a client for a manifest for media content for a particular temporal range or subset of playback options.

Manifest partitioning

Methods and apparatus are described for generating manifest files for media content playback. A server can generate manifest files that include initialization metadata obtained from initialization fragments of media content files. Client devices can initiate playback of media content for playback using the manifest files without downloading or parsing the initialization fragments of the media content files.

Customized dash manifest

Methods and apparatus are described for segmenting a manifest file to generate smaller manifest files for media content playback. A server can segment a manifest file prior to receipt of a request from a client or in response to a request from a client for a manifest for media content for a particular fragment range.

Manifest segmentation

Technologies pertaining to attesting to computer-executable code residing on a robot are described herein. An attestation server includes a database that comprises file paths that correspond to files on the robot at a time of manufacture of the robot. The database also includes file digests that are indicative of content of the files on the robot. The attestation server randomly selects a file path and transmits the file path to the robot. The robot accesses the file at the file path and computes a file digest for that file. The robot then transmits the file digest to the attestation server, which compares the file digest from the robot with the file digest in the database. If the file digests match, then the attestation server attests to the computer-executable code on the robot.

Random file request for software attestation

The claimed subject matter provides a system or method for managing software changes. An exemplary method comprises creating a reset boot loader, a last known good (LKG) boot loader, and a current boot loader, then pointing the reset boot loader, LKG boot loader, and current boot loader to a parent virtual hard disk (VHD) containing a default master image. An operation to perform is determined, and a service partition is booted into. The LKG boot loader or current boot loader is pointed to a child VHD loaded with another desired image based on the operation selected, and the system is rebooted into the parent VHD or child VHD pointed to by the current boot loader.
