Abstract: A communication application displays a modality view that may be one of a collaboration, a gallery, or a messaging view on a conversation canvas. The application may display an initial view according a modality selection by the user. A user is enabled to select a next view from the set by providing a user action such as a tap, swipe action, etc. The application dynamically generates the next modality view according to the initial view. Common participants and common contexts are used to configure the next view. Subsequent to configuration, the application displays the next modality view on the conversation canvas by transitioning from the initial view. The application retains session information from the initial view to restore the initial view session if the user selects to return to the initial view.

Abstract: Signaling from a mobile device is transparently tunneled through a cellular voice network to a Voice over Internet Protocol (“VoIP”) core network so that multi-party calls, including conference calls and call waiting, can be managed entirely within the VoIP core network. The tunneled signals enable call control to be implemented in the VoIP core network and also establish a way to communicate requests, instructions, and call state. The signaling is transparent to the cellular network because that network does not receive and interpret the signaling. Instead, the cellular network's existing and unmodified control plane is repurposed by the mobile device by placing new, brief outgoing calls through the cellular network to the VoIP core network where the called party number (i.e., the caller-ID) encodes specific information. The VoIP core network immediately releases the new cellular call once the caller-ID is received and the encoded information is interpreted.

Abstract: A file system layout apportions an underlying physical volume into one or more virtual volumes (vvols) of a storage system. The underlying physical volume is an aggregate comprising one or more groups of disks, such as RAID groups, of the storage system. The aggregate has its own physical volume block number (pvbn) space and maintains metadata, such as block allocation structures, within that pvbn space. Each vvol has its own virtual volume block number (vvbn) space and maintains metadata, such as block allocation structures, within that vvbn space. Notably, the block allocation structures of a vvol are sized to the vvol, and not to the underlying aggregate, to thereby allow operations that manage data served by the storage system (e.g., snapshot operations) to efficiently work over the vvols. The file system layout extends the file system layout of a conventional write anywhere file layout system implementation, yet maintains performance properties of the conventional implementation.

Abstract: A communication application displays a conversation navigation bar to manage conversations. The application inserts an interactive tile into the navigation bar for each conversation. Each tile presents status information about the conversation and the modality of the conversation. Tiles are ordered according to activity and updates. The navigation bar is adjustable to accommodate hardware and software limitations of a platform.

Abstract: An encoding manager facilitates robust single-pass variable bit rate video encoding of a video sequence. Before encoding the video sequence, the encoding manager determines the size of a buffer to use for keeping track of over/under used bits generated during encoding. The encoding manager uses the target bit rate for the video sequence and the length of the video sequence to determine the size of the buffer. After allocating bits to a frame of the sequence, the encoding manager determines the quant to use to encode that frame. The determination of a quant to use to encode a frame is informed by the fullness of the buffer. The encoding manager adjusts the quant to use (and thus the aggressiveness of its encoding) in response to the amount of overflow generated thus far by the encoding of the video sequence.

The system comprises a processor; zero or more hardware components coupled with the processor; and a memory coupled with the processor and comprising a set of processor-executable instructions. The instructions comprise a component handling state machine responsive to at least one of a kernel component or a userspace component; and at least one component interface thread in communication with the component handling state machine and configured to interact with at least one of the zero of more hardware components responsive to a signal from the component handling state machine.

Abstract: In one embodiment of the present invention, a method and system are provided to control access to the non-volatile log (NVlog) of a storage server. By controlling access to the NVLog of a storage server the relative disk write bandwidth available to different client write requests can be controlled. The incoming write request can be categorized, and, during times of heavy load, only be permitted to use NVLog space as permitted based on the categorization of each write request. In one embodiment, the present invention includes receiving a write request from a client at a storage server, and determining whether the received write request can be presently logged in a NVlog based on a category of the write request.

Abstract: A memory management system for managing memory of a processing device and a corresponding method thereof. The system comprises a memory manager and a garbage collector. The memory manager is configured to allocate memory after dividing discrete units of memory into smaller units. The garbage collector is configured to organize a memory availability collection of free units of memory in the memory manager. The collection is ordered based on at least one of the amount of each of the discrete units available and the allocation age of the discrete units.

Abstract: The present invention provides a system and method for flexible space reservations in a file system. An administrator of a storage system selects a fractional reserve percentage, which defines the size of the overwrite reserve that is to be maintained to ensure file writeability.

Abstract: An underlying physical volume of a storage system is an aggregate having a plurality of storage devices. The aggregate has its own physical volume block number (pvbn) space. A file system layout apportions the underlying physical volume into a plurality of virtual volumes of the storage system each having a virtual volume identification (vvid). Each virtual volume has its own virtual volume block number (vvbn) space. The block allocation structures of a virtual volume are sized to the virtual volume, and not to the underlying aggregate, to thereby allow operations that manage data served by the storage system (e.g., snapshot operations) to efficiently work over the virtual volumes. Each storage block in a virtual volume is identified by the triplet: pvbn, vvid, and vvbn.

Abstract: A computer data storage system is described. A processor maintains a striped volume set by striping a data container over a plurality of storage nodes. A storage node determines whether space available on that node is below a predetermined threshold, the predetermined threshold indicating a low-in-space state. The storage node sends a message indicating that the storage node is in a low-in-space state. The processor accepts no further write messages to the data container as long as the storage node is in a low-in-space state.

Abstract: A technique uniquely identifies block context signatures in a storage volume hierarchy of a storage system. In particular, the technique assigns unique volume identifiers (“IDs,” e.g., buffer tree or “bufftree” IDs) to volumes of the storage volume hierarchy, and allows clone volumes to determine that data blocks belong to an appropriate ancestor volume (e.g., and were written by the ancestor volume prior to creation of the clone). In this manner, the novel technique may uniquely identify and accurately determine whether an accessed data block is a correct data block (e.g., alleviating occurrences of data ID aliasing).

Abstract: A system and method for managing data during consistency points in a storage system is provided. A buffer data control structure is modified to include a flags array that tracks various status flags for both a current and a next consistency point (CP). By utilizing multiple pointers within a buffer control structure, the storage system may permit write operations to continue to a data container undergoing write allocation. Received writes during a write allocation procedure are stored in raw data buffers and the buffer control structure is marked as being dirty for a next CP.

Abstract: A system and method are provided to manage storage space. The method comprises detecting a free storage space threshold condition for a storage volume and automatically applying a space management technique to achieve a free storage space threshold condition. Space management techniques comprise deleting selected backup data (e.g., persistent consistency point images) and automatically increasing the size of the storage volume.
