摘要： Improved systems and methods for implementing data-driven protocols are provided. In one embodiment, improved implementations of multicast routing protocols are provided. Separation between multicast forwarding and control elements are provided by use of a powerful yet simple application program interface (API) for inter-module communication. The API is multicast-routing-protocol-independent and can be used to express the forwarding state of any existing multicast protocol. Efficient platform-specific implementations are facilitated.

摘要： Methods and apparatuses are provided that facilitate providing an object-based transport protocol that allows transmission of arbitrarily sized objects over a network protocol layer. The object-based transport protocol can also provide association of metadata with the objects to control communication thereof, and/or communication of response objects. Moreover, the object-based transport protocol can maintain sessions with remote network nodes that can include multiple channels, which can be updated over time to seamlessly provide mobility, increased data rates, and/or the like. In addition, properties can be modified remotely by network nodes receiving objects related to the properties.

摘要： A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.

摘要： A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. A client device can be adapted to take advantage of the ingestion process. The client device might be configured to optimize use of resources, given the information available to it from the ingestion system. This may include configurations to determine the sequence, timing and construction of block requests based on monitoring buffer size and rate of change of buffer size, use of variable sized requests, mapping of block requests to underlying transport connections, flexible pipelining of requests, and/or use of whole file requests based on statistical considerations.

摘要： Disclosed are systems, methods and computer program products for preemptive DNS resolution. A DNS proxy is provided for inspecting data packets transmitted to a client device on a first communication link. The proxy identifies one or more host device names embedded in the inspected data packets and resolves IP addresses associated with the embedded host device names. The proxy device transmits the inspected data packets to the client device without alterations on a second communication link. The second communication link has significantly higher propagation latency than the first communication link. The proxy then transmits to the client device, independent of the inspected data packets, the one or more host device names and the associated resolved IP addresses for use by the client device to establish connections to the host devices identified in the inspected data packet.

摘要： A communications system can provide methods of dynamically interleaving streams, including methods for dynamically introducing greater amounts of interleaving as a stream is transmitted independently of any source block structure to spread out losses or errors in the channel over a much larger period of time within the original stream than if interleaving were not introduced, provide superior protection against packet loss or packet corruption when used with FEC coding, provide superior protection against network jitter, and allow content zapping time and the content transition time to be reduced to a minimum and minimal content transition times. Streams may be partitioned into sub-streams, delivering the sub-streams to receivers along different paths through a network and receiving concurrently different sub-streams at a receiver sent from potentially different servers. When used in conjunction with FEC encoding, the methods include delivering portions of an encoding of each source block from potentially different servers.
