摘要： The present invention addresses the issue of jitter and clock drifting in streaming media applications. The present invention utilizes the Real Time Transaction Protocol (RTP) to embed MPEG packets within RTP packets in a Multiple Program Transport Stream (MPTS). Each MPEG packet in an MPTS stream is tagged at a gateway with: an arrival timestamp, a per-flow index and internal index to identify where the packet resides in an RTP packet and within a stream. After demultiplexing, this information is utilized in conjunction with the sending timestamp of each RTP packet to create a sending time for each MPEG packet to aid in the reduction of jitter and clock drifting.

摘要： A write operation writes first data to a target logical address range included in a first logical address range of a virtually provisioned device. It is determined that physical storage is not allocated for the target logical address range. First processing is performed to allocate a first portion of physical storage having a first corresponding logical address subrange that includes the target logical address range. The first portion is allocated from a physical device included in a first storage tier. The first processing includes selecting the first storage tier from multiple storage tiers in accordance with selection criteria including metrics characterizing an expected workload or level of activity for the first corresponding logical address subrange of the virtually provisioned device. Mapping information is updated to indicate that the first corresponding logical address subrange of the virtually provisioned device maps to the first portion of physical storage.

摘要： A method is described that includes receiving a program request from a transceiver that includes a program request to receive a video program at the transceiver. The method also includes determining an amount of bandwidth on a channel available to the transceiver. The method further includes determining whether to provide a unicast stream or a multicast stream to deliver the requested video program to the transceiver in response to the program request based on a result obtained after implementing a policy control function that considers an amount of bandwidth on the channel to the transceiver. The method further includes formatting and selecting an incoming media stream in accordance with the result of the policy control function to provide a corresponding formatted unicast or multicast media stream that includes video data for the requested video program. The method further includes outputting the associated formatted unicast or multicast media stream on the channel.

摘要： A networked data storage system includes data movement logic and a virtual machine for executing a data management processing plan which is generated by a facility outside the storage array based on statistical information associated with extent level activity metrics provided by the storage array. Dynamically updated and automatically generated data management processing plans are provided to the storage array in the form of units of compiled byte code which the storage array is able to verify and execute using a virtual machine. The virtual machine interfaces with the environment in which it is embedded in a carefully constrained manner, thereby preventing clearly undesirable operations.
