Apparatus, systems and methods for pre-processing, analyzing, and storing genomic data through a scalable, distributed analysis system across a network is presented.

This document describes, among other things, a router providing service-enabled multicast forwarding for a flow-based architecture. Services are enabled using inbound / outbound policies from Access Control Lists (ACLs). In a first mode, per-flow services are not enabled, and flows are aggregated for efficiency. In a second mode, per-flow services are enabled, and control information for an outbound interface (OIF) is shared across all multicast flows that do not have per-flow service enabled. A flow management scheme for these modes allows dynamic multicast membership updates while reducing disruption of active flows. This supports a large multicast OIF list and a high rate of multicast “Joins” and “Leaves”. This provides scalability and performance, such as desired for deploying multicast for broadband subscriber applications.

Mechanisms are provided to manage media stream transmissions at a content server. A content server detects that a user on a device such as a mobile device has stopped playing a live media stream. The content server maintains information associating the user with the media stream and time information. When the content server detects that a user wishes to resume playing a media stream, the user can continue viewing the media stream from where stoppage occurred. In many instances, the content server stores many hours of live media stream data and allows a user to select a particular starting point.

A client device presents streaming media and includes a stream manager for controlling streams, a request accelerator for making network requests for content, a source component coupled to the stream manager and the request accelerator for determining which requests to make, a network connection, and a media player. The request accelerator can accelerate a download rate using a plurality of TCP connections. A target download rate can vary among HTTP requests. The TCP receiver window size for a given TCP connection might be based on the target download rate for that TCP connection and / or a current estimated round-trip time for the current TCP connection multiplied by a multiplier rate, wherein the multiplier rate is within a range bounded by the target download rate for the current TCP connection and a rate that is higher than the target download rate by a predetermined amount.

A flow authority control system of the workflow management system, wherein a character management module comprises a dynamic character management module consisting of sub-modules for managing the flow starter character, the flow manager character, the flow handler character, and the flow operation.

By adopting the dynamic character module to control the flow authorization mechanism, the flow right control becomes more flexible and strict.

A network communication system includes one or more talkers that may communicate data streams to one or more listeners over a network, such as an Ethernet Audio / Video Bridging network. Before transmitting a new data stream, a talker may request a reservation for bandwidth through a controller that is configured to manage and / or control the flow of data streams over the network. If there is not enough bandwidth, then the controller may determine whether any existing data streams may be transmitted at lower bandwidths to make available enough bandwidth for the new data stream. Alternatively, the controller may determine whether any existing data streams having lower priorities than the new data stream may be terminated to make available enough bandwidth for the new data stream.

A stream manager provides a way of redirecting and managing messaging and information access in a packet network environment. The stream manager can include a computer-based router or server that behaves as if it were a gateway for a sub-network of destination site servers, and the stream manager is linked to a packet network, such as the Internet. The stream manager receives over the packet network a message from a user's host server initiated by a user and intended for a destination site. The message bears an address for the stream manager which is provided to the host server by the address server for the packet network, such as a server utilized as part of the domain name system. The stream manager determines the availability of at least one destination server at the destination site to receive and process the message. If a destination server at the destination site is available to receive and process the message, the stream manager selects a destination server from those available, and initiates the routing of the message to the selected destination server. If a destination site is unavailable, the stream manager may report that to the host server, along with other information (such as customer care or promotional information).

A data processor for executing branch prediction comprises a queuing buffer (23) allocated to an instruction queue and to a return destination instruction queue and having address pointers managed for each instruction stream and a control portion (21) for the queuing buffer. The control portion stores a prediction direction instruction stream and a non-prediction direction instruction stream in the queuing buffer and switches an instruction stream as an execution object from the prediction direction instruction stream to the non-prediction direction instruction stream inside the queuing buffer in response to failure of branch prediction. When buffer areas (Qa1, Qb) are used as the instruction queue, the buffer area (Qa2) is used as a return instruction queue and the buffer area (Qa1) is used as a return instruction queue. A return operation of a non-prediction direction instruction string at the time of failure of branch prediction is accomplished by stream management without using fixedly and discretely the instruction queue and the return destination instruction queue.
