    摘要： Technologies are described herein for buffer management during real-time streaming. A video frame buffer stores video frames generated by a real-time streaming video capture device. New video frames received from the video capture device are stored in the video frame buffer prior to processing by a video processing pipeline that processes frames stored in the video frame buffer. A buffer manager determines whether a new video frame has been received from the video capture device and stored in the video frame buffer. When the buffer manager determines that a new video frame has arrived at the video frame buffer, it then determines whether the video processing pipeline has an unprocessed video frame. If the video processing pipeline has an unprocessed video frame, the buffer manager discards the new video frame stored in the video frame buffer or performs other processing on the new video frame.

    摘要： Technologies for handling early media in VoIP communications with multiple endpoints are provided. A calling device sends an initial VoIP call request to multiple destination devices, or endpoints. The calling device then receives a provisional response from one or more of the destination devices that includes media streaming parameters regarding the destination device. The calling device creates a media context associated with the destination device that contains the media streaming parameters and stores the media context. The calling device uses the media context to establish a media connection with the destination. One of the destination devices returning a provisional response is selected to exchange early media over the media connection established with the destination device.

    摘要： Technologies are described herein for detecting and managing congestion on a shared network link. A determination is made whether the shared network link is congested based on loss rate and round-trip time (RTT) between a computer and a receiver operatively coupled by the shared network link. Upon determining that the shared network link is congested, a back-off operation is performed on the computer. The back-off operation may reduce an allocated bandwidth of the computer on the shared network link by transforming a higher allocated bandwidth into a lower allocated bandwidth.

    摘要： Embodiments are configured to provide communication environments to communicating participants using a number of modality control features, but are not so limited. In an embodiment, a system includes a communications manager to manage an amount of available communication bandwidth to a number of communication modalities that include an audio modality, a video modality, an application sharing modality, and/or a file transfer modality. In one embodiment, available bandwidth can be distributed by controlling an audio state, a video state, an application sharing state, and/or a file transfer state, including using first and second distribution ratios as part of allocating available bandwidth.

    摘要： Instead of utilizing a centralized server or hardware (routers/gateways) to enforce connectivity policy restrictions, the policy connectivity restrictions for media session traffic are enforced by an endpoint that is involved in the media communication. Based on the policy requirements, the client enforces the policy restrictions by restricting the candidates that may be selected for the establishment of the media path. For example, the enforcement may result in the client selecting a path from available candidates that avoids congested Wide Area Network (WAN) links, avoiding a low bandwidth link, or possibly even failing the communication completely. The clients may also provide periodic updates to the policy server to allow tracking of the utilization of managed WAN links.

    摘要翻译： 不采用集中式服务器或硬件（路由器/网关）来强制执行连接策略限制，媒体会话流量的策略连接限制由媒体通信中涉及的端点执行。 根据策略要求，客户端通过限制可能被选择用于建立媒体路径的候选者来强制执行策略限制。 例如，执行可能导致客户端从可用的候选者中选择一条路径，以避免拥塞的广域网（WAN）链路，避免低带宽链路，甚至可能甚至完全失败通信。 客户端还可以向策略服务器定期更新，以便跟踪受管WAN链路的利用率。
