In an exemplary device implementation, a device includes: a connection migrator that is configured to migrate connections away from the device; the connection migrator capable of precipitating a compilation of protocol state for a connection across a protocol stack; the connection migrator adapted to aggregate the compiled protocol state with data for the connection into an aggregated connection state; the connection migrator further capable of causing the aggregated connection state to be sent toward a target device. In an exemplary media implementation, processor-executable instructions direct a device to perform actions including: obtaining at least a portion of a source/destination pair from a packet; accessing an encapsulation mapping table using the at least a portion of the source/destination pair to locate an encapsulation mapping entry; extracting a flow identifier from the encapsulation mapping entry; and replacing part of the packet with the flow identifier to produce an encapsulated packet.

In an exemplary method implementation, a method includes: receiving a packet requesting a new connection at a forwarding component; sending the packet from the forwarding component to a classifying component; selecting, by the classifying component, a route for the new connection; and plumbing, by the classifying component, the route for the new connection by causing a new entry to be added in a local routing table of the forwarding component. In an exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to perform actions including: receiving a first packet for a connection at first forwarding functionality; plumbing a route for the connection at the first forwarding functionality; receiving a second packet for the connection at second forwarding functionality; and plumbing the route for the connection at the second forwarding functionality using a distributed session tracking table.

In an exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to facilitate actions including: operating network load balancing infrastructure in a first configuration; scaling out the network load balancing infrastructure; and operating the scaled-out network load balancing infrastructure in at least one other configuration. In another exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to be configured such that different percentages of system resources may be allocated to different network-load-balancing functions. In one embodiment, the scaling out includes moving at least a portion of network-load-balancing functionality from a device that executes host functionality to another device, that does not execute host functionality and routing network traffic from the other device to the host functionality executing on the device.

Media collections (MC) service embodiments are presented which generally facilitate access to diverse forms of media by resolving an identifier tuple assigned to a content item into a set of one or more Uniform Resource Identifiers (URIs) which point to an instance of the content item. This scheme supports the upload and query of collections of media elements such as images, audio, video, deep zoom images, photosynth and so on. In addition, the foregoing scheme affords a standard way to bind to media that persists, and makes it easier to author and play content while being flexible about where the media is located.

“Experience Streams” (ESs) are used by a “rich interactive narrative” (RIN) data model as basic building blocks that are combined in a variety of ways to enable or construct a large number of RIN scenarios for presenting interactive narratives to the user. In general various ES types contain all the information required to define and populate a particular RIN, as well as the information (in the form of a series of navigable states) that charts an animated and interactive course through each RIN. In other words, combinations of various ES provide a scripted path through a RIN environment, as well as various UI controls and/or toolbars that enable user interaction with the interactive narrative provided by each RIN. Example ESs include, but are not limited, content browser experience streams, zoomable media experience streams, relationship graph experience streams, player-controls/toolbar experience streams, etc.

A method, apparatus, and computer program product provide applications and application developers with generic access from user mode to the L2CAP layer of Bluetooth by exposing the L2CAP layer to user mode via a socket interface. In particular, a kernel mode primary component and user mode helper component cooperate to expose a Winsock interface to user mode components, and to manage various Bluetooth-specific functions and operations, allowing a user mode user application to access Bluetooth functionality without providing Bluetooth-specific commands or actions, and without being required to use RFCOMM.
摘要:
An automated task centered collaboration technique is described that significantly lowers the technological entry barrier for the development and deployment of a broad class of collaborative applications, which are termed Task Centered Collaboration (TCC) applications. TCC applications facilitate the processing of a large number of work items, or tasks, by people working independently or in small, synchronously collaborating groups. The technique also provides a mechanism for the study of computer mediated communication and human-computer interactions for this class of applications. The technique creates an abstraction applicable to the broad class of TCC applications, which enables the factoring out of significant portions of the application into a common infrastructure. It provides a programming model that enables a developer to focus on the User Interface and logic associated with operations on a single task, without being exposed to issues such as security, authentication, binding users to activities, synchronization, concurrency and persisting data.

In a first exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: accumulating host status information at multiple hosts; and sending the accumulated host status information from the multiple hosts. In a second exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: receiving host status information from multiple hosts; and making load balancing decisions responsive to the received host status information. In a third exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: determining health and load information on a per application basis; and selecting an application from among multiple applications responsive to the health and load information.
摘要:
The invention provides quality-of-service (QoS) delivery services over a computer bus having isochronous data transfer capabilities. A transmitting node on the bus transmits a message to an intended recipient indicating a requested bandwidth for a connection. If the intended recipient has sufficient resources, it allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits the data on the allocated channel. If the recipient cannot allocate a channel, it does not respond, and the transmitter thereafter detects a time-out condition and begins transmitting using a “best efforts” scheme (i.e., non-guaranteed time delivery). In a second variation, a receiving node detects that it is receiving large quantities of data from a transmitting node. In response, the receiving node allocates an isochronous data channel on the bus and notifies the transmitter of the allocated channel. Thereafter, the transmitter transmits using the allocated isochronous channel. In a third variation, multiple receiving nodes that need to receive streaming data from a single transmitting node share a common isochronous data channel. In any of these variations, each receiver can periodically transmit a “deadman” timer message on a broadcast channel to indicate that it is still receiving on a given channel. If a transmitter detects that the deadman timer has expired, it reverts to transmitting data using a “best-efforts” scheme. A transmitter can transmit both to receivers that can handle QoS services and those that cannot explicitly support QoS services.
摘要:
A custom palette comprises colors on a plurality of luminance levels consisting of colors of uniform luminance. The spacing in luminance between levels varies in relation to the luminance, the spacing between levels being closer at low luminance and increasing at greater luminance. The palette preferably includes a gray color from each luminance level, highly saturated colors at the vertices of every alternate level, and a selection of lower saturation colors encircling the gray color on each level. The selection of lower saturation colors preferably includes a higher concentration of flesh and sky colors.
