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 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: The present disclosure is directed to systems and methods for identifying and providing highlight messages from a group messaging thread. For example, systems and methods described herein detect when a group messaging thread participant becomes absent from the group messaging thread, and identifies one or more highlight messages that were submitted to the group messaging thread while the participant was absent. Systems and methods described herein identify highlight messages that are specific to the absent participant, such that when the participant again accesses the group messaging thread, the participant can review the identified highlight messages in order to quickly “catch up” on the group messaging thread without having to read each electronic message submitted to the group messaging thread during the participant's absence.

Abstract: A system, apparatus, graphical user interface and methods are provided for conducting electronic voice communications with status notifications. A user of a first portable device executing a communication application selects a multi-function control that automatically initiates an audio recording, which is automatically sent toward another participant of an active communication session when the control is released. The same multi-function control may be used to transmit a textual message. A representation of the recording is displayed on the user's device, with an indicator that changes appearance when the other participant plays the recording. In addition, when one user initiates an audio recording that will be automatically sent to another user, the other user's device is advised of the initiation of recording and displays that status for the other user.

Abstract: Techniques to perform the dynamic configuration of load-balanced relay operations are described. In one embodiment, an apparatus may comprise a first load balancer component, a second load balancer component, a first relay server component, a second relay server component, and a persistent shared-memory storage component. The apparatus may be operative to perform the dynamic configuration of load-balanced relay operations for a two-tier relay system using persistent shared-memory storage in which a session identifier received from client devices is used to coordinate the activities of the relay server components based on information shared via the persistent shared-memory storage component. Other embodiments are described and claimed.

Abstract: A server receives a request for a business account with the messaging system that includes a business name and a contact point. The server determines whether users of the messaging system associate the business name with the contact point. The server also determines whether the business name and/or the contact point has characteristics consistent with the request originating from a genuine business. The business account is validated if users of the messaging system associate the business name with the contact point and at least one of the business name or the contact point have characteristics consistent with the request originating from a genuine business. The business account profile is updated to indicate it is verified. Client devices are adapted to display messages from the business account in conjunction with a visual indicator that the business account is verified.
