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: Two (or more) client devices engage in a chat session. Packets associated with the chat session are numbered using a predetermined pattern. When the packets are received, the receiving client device extracts signals from the packet metadata to determine whether the primary cause of packet loss during transit is network congestion or link losses. Based on the extracted signals, the receiving device sends a control message back to the other client device indicating how one or more chat parameters should be updated. On receiving the control message, the other client device updates the chat parameters accordingly.

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: Aspects of the present disclosure describe an end-to-end communication protocol for interactive applications that ensure high throughput and low delay. A sender device and a receiver device are in communication with each other through a network. As multimedia content is captured by the sender device, the sender device packetizes each frame of the multimedia content into a plurality of packets thereby creating a packet train of packets that are sent to the receiver the device. The receiver device models the behavior of the network based on a continuous distribution. Based on the model of the network, the receiver device generates a forecast that describes the amount of data that the sender device can send to the receiver device. The receiver device sends the forecast to the sender device which subsequently sends data to the receiver device according to the forecast.

Abstract: Techniques to scan and reorganize media files to remove gaps are described. In one embodiment, an apparatus may comprise a media handling component operative to receive a media file, the media file comprising a header portion and an encoded media portion, the header portion comprising one or more indexing tables, the encoded media portion comprising a plurality of encoded chunks; a media topology component operative to build an encoded media topology list by scanning the one or more indexing tables; and a media rebuilding component operative to build the media file into a rebuilt media file by copying the plurality of encoded chunks while generating one or more replacement indexing tables where the encoded media topology list indicates that the encoded media portion contains one or more unreferenced portions. Other embodiments are described and claimed.

Abstract: Techniques for managing a remote web client from an application on a mobile device are described. In one embodiment, an apparatus may comprise a messaging application operative on the processor circuit to receive a request from a remote web browser, the request for the remote web browser to receive messaging updates from the messaging application; establish an encrypted connection between the messaging application and the remote web browser; receive a messaging update at the messaging application; and transmit the messaging update from the messaging application to the remote web browser. Other embodiments are described and claimed.

Abstract: A system and methods are provided for aggregating communication connections. Multiple users connect to a system (e.g., a web-based system) that hosts an application or service for exchanging communications. Users who exchange communications among themselves may be considered “associates.” When one user who is on-line with the application sends a communication through the system for an associate, the system determines whether the associate is on-line or off-line. If the associate is off-line, the system crafts and sends toward the associate a notification regarding the communication, including an address of the communication server to which the one user is connected. When the associate's device receives the notification, the application may attempt to connect to the specified address. In this way associated users' connections will aggregate or gravitate toward the same communication server, thereby eliminating the latency and cost of exchanging users' communications between multiple communication servers.

Abstract translation: 提供了一种用于聚合通信连接的系统和方法。 多个用户连接到承载用于交换通信的应用或服务的系统（例如，基于web的系统）。 在彼此之间交换通信的用户可以被认为是“关联人员”。当与应用程序联机的一个用户通过系统发送通信以进行联系人时，系统确定该联系人是在线还是离线。 如果员工离线，则系统向员工发送关于通信的通知，包括与一个用户连接的通信服务器的地址。 当员工的设备收到通知时，应用程序可能尝试连接到指定的地址。 以这种方式，相关联的用户的连接将聚集或引向同一个通信服务器，从而消除了在多个通信服务器之间交换用户的通信的延迟和成本。
