Abstract: Techniques to dynamically configure target bitrate for streaming network connections are described. An apparatus may comprise a streaming component operative to establish a streaming network connection with a second client device at a first client device; and a stream configuration component operative to determine inter-arrival rate information for the streaming network connection; provide the inter-arrival rate information to an inter-arrival rate analysis component; receive a preliminary target bitrate from the inter-arrival rate analysis component in response to providing the inter-arrival rate information to the inter-arrival rate analysis component; determine round-trip time information for the streaming network connection; determine an assigned target bitrate and a packet size setting for the streaming network connection based on the preliminary target bitrate and the round-trip time information; and configure the streaming component to perform the streaming network connection with the assigned target bitrate and the packet size setting. Other embodiments are described and claimed.

Abstract: A method, apparatus and computer program product is provided for processing the status of phone devices having a phone number. A synthetic communication server receives updated status of a target phone device referencing a normalized phone number that specifically identifies the target phone device on a synthetic communication network. Accordingly, the server stores the updated status of the target phone device in a status area referenced by the normalized phone number. The server identifies a subset of phone devices from phone devices on the synthetic communication network interested in the status of the target phone device. For each of the phone devices in the subset, the server pushes the updated status of the target phone device to each phone device in the subset.Yet another aspect of the invention concerns monitoring status of the phone devices in a status list of normalized phone numbers on a phone device. The phone device monitors other phone devices and also provides individual status. Accordingly, the method and system sends the status list and updated status of the phone device that includes a normalized phone number identifying the phone device on the synthetic communication network. Subsequently, the method and system receives the status updates of the one or more other phone devices in the status list. The status updates received are also referenced using the corresponding normalized phone numbers for each of the other phone devices. These status updates of the one or more other phone devices are processed by the method and system and then displayed in a display area of the phone device.

Abstract: An apparatus may include a messaging server component operative to determine a sharing event for a data item, the sharing event associated with a source client device with a local storage of the data item. The apparatus may request that the source client device upload the data item to a destination storage device in response to a determination that network storage of the data item is scheduled for relocation from a source storage device to the destination storage device. The apparatus may include a storage management component operative to determine that the network storage of the data item is scheduled for relocation from a source storage device to a destination storage device and de-schedule the relocation of the data item.

Abstract: A system and methods are provided for conveying connection-oriented communications (e.g., textual messages among multiple users) via a protocol such as HTTP (Hypertext Transfer Protocol). When a device operating a communication application that features a custom application layer protocol for formatting messages for transmission cannot connect to the system hosting the application using a default protocol stack that include the custom application layer protocol, it instead connects using HTTP's chunked mode of transfer encoding. Each outgoing communication is encapsulated in a separate HTTP chunk, and communications to multiple different users may be conveyed via the one connection. Incoming communications (e.g., from the multiple users) are received as separate chunks and are unwrapped or de-encapsulated to retrieve the communication for presentation to a user.

Abstract: Aspects of the present invention include method and systems or processing multimedia data exchanged between mobile devices. Initially, a transmitting mobile device attempts to send multimedia data formatted in a primary format even though a receiving mobile device cannot process the data. The multimedia data in the primary format is then uploaded to a multimedia communication server where the multimedia data can be transcoded on demand into a secondary format that the receiving mobile device can indeed process. To track the multimedia data, the transmitting mobile device receives a multimedia identifier associated with the multimedia data uploaded to the multimedia communication server. Instead of sending the multimedia data, the transmitting mobile device forwards the multimedia identifier to the receiving mobile device allowing the receiving mobile device to demand transcoding the multimedia data into a secondary format on the server that the receiving mobile device is capable of receiving and processing.

Abstract: A system, apparatus, and methods are provided for supporting automated recall of a message (e.g., a chat message) from an originator's device, or at least media that accompanied the message. An original message may convey one or more media files that are temporarily stored on a system or apparatus that hosts the communication application used to create, send, and receive messages. The media files may be lost in transit because of failure of a system component, failure of a storage device, purging of the files before they are retrieved by a recipient, or for some other reason. When the recipient's device receives an error in response to an attempt to retrieve the media file(s), it automatically initiates a recall request that is returned to the originating device. If the message and media are still available on the device, an abbreviated version of the message is re-sent, with the media.

Abstract: A system and methods are provided for dynamically muting or suppressing notifications of new communications. When a new communication is received for a user of a communication device (e.g., a mobile telephone, a computer) while notifications are muted, no notification may be issued to the user or, alternatively, a muted notification that differs from a normal notification may be issued. A muted notification may have muted sound or no sound, abbreviated vibration or no vibration, or may otherwise be a dampened version of a normal notification. Dynamic muting may be applied or managed on the user's device or on a system that hosts the communication application for which notifications are muted. Different applications and/or communication sessions (e.g., different chat groups) may be muted differently (e.g., for different periods of time). When a group chat session is muted, the duration of muting may be proportional to the number of participants.
