摘要： A data stream recorder system, for multi-stream recording and retrieval of utilizes a number of gateways, each for sending and receiving packets containing streaming multimedia content data at real-time rates via a packet data network. A session manager communicates via the network with source client devices and receiver client devices, to establish and control recording and retrieval sessions. The manager assigns sessions to the gateways for the sending and receiving of the packets to and from client devices. Content is distributed across storage devices associated in storage nodes. Each of the gateways receives packets containing content data at real time rates during a recording session and distributes the received packets from the session across all of the storage nodes. A scheduler of each respective storage node distributes content data from packets distributed to the respective storage node, across all of the digital storage devices of the respective storage node.

摘要： Systems and techniques for transmitting data stream to a client include transmitting a data segment from one of a plurality of nodes of a continuous media server to a client according to a scheduler on the node. A system includes a plurality of data processing devices, each data processing device coupled with at least one storage device. Each data processing device includes a scheduler to schedule transmission of the data segment to a client in sequence with other data segments, and a module to transmit the data segment to the client.

摘要： Admission of a new disk stream is based on probability of overcommitting disk bandwidth based on parameters related to the disk. This fixed parameters are determined either by obtaining or by investigating the desk. Probability functions of the disk parameters may be obtained. Exemplary disk parameters may be disk seek time, probabilistic determination of the amount of data exchange during a single exchange, and probabilistic information about reading versus writing.

摘要： Systems and techniques are provided for using a multi-threshold buffer model to smooth data transmission to a client. A client to receive data such as streaming media data may include a buffer. A server to transmit data to the client may transmit the data to the client at a first server transmission rate. The client buffer level may be determined at different times; for example, a first buffer level may be determined at a first time and a second buffer level may be determined at a second time. If the buffer level is at a threshold level or has passed a threshold level between the first and second times, server transmission rate information may be determined and may be sent to the server.
