摘要： Methods and systems are provided herein for initiating real-time, peer-to-peer communication from a collaborative session. Real-time, peer-to-peer communication includes sharing content such as media content over a peer-to-peer connection such as peer-to-peer conferencing, for example. More particularly, from within the collaborative session where a plurality of clients collaboratively interact with a remotely-accessed application, for example, the systems and methods enable discovery of the clients actively participating in the collaborative session (e.g., peer nodes) and enable establishment of peer-to-peer connection(s) between pairs of the clients.
摘要翻译：本文提供了用于启动来自协作会话的实时，点对点通信的方法和系统。实时的点对点通信包括例如通过点对点连接共享诸如媒体内容的内容，例如对等会议（peer-to-peer conferencing）。更具体地说，从多个客户端与远程访问的应用程序协作交互的协作会话内，例如，系统和方法使得能够发现主动参与协作会话的客户端（例如，对等节点），并且能够建立客户端对之间的对等连接。

摘要： Systems and methods for providing a connection of a client to an unmanaged service in a client-server remote access system. An unmanaged service may register at a remote access server and open a communication connection there between remote access server may be configured for providing remote access to the unmanaged service by a client. The remote access server receives keep-alive messages from the unmanaged service over the communication connection, which may serve to indicate that the unmanaged service is operational. The remote access server may a request for a client connection to the unmanaged service, after which, a terminate keep-alive message is communicated to the unmanaged service to terminate the sending of keep-alive messages from the unmanaged service in response to the request for the client connection to the unmanaged service.

摘要： A client-side flow control mechanism for controlling the flow of messages communicated from a service to a client in a remote access system. The service, which may be a managed or unmanaged service, may communicate messages to the client where the messages include a service sequence ID (SSI). As the client processes the messages from the service, the client responds with a client sequence ID (CSI). The SSI and CSI values determine the number of messages that are in transmission queues. The service compares a difference between the current SSI and CSI to a stop window value. If the difference is greater than the stop window value, transmission of messages from the service to the client is turned OFF. The client continues to send CSI acknowledgments as it processes messages. Once the difference falls below a start window value, the transmission of messages to the client is turned ON.
摘要翻译：一种用于控制从远程访问系统中的服务传递到客户端的消息流的客户端流控制机制。可以是被管理或非托管服务的服务可以向客户端传送消息，其中消息包括服务序列ID（SSI）。当客户端处理来自服务的消息时，客户机以客户端序列ID（CSI）进行响应。 SSI和CSI值确定传输队列中的消息数。该服务将当前SSI和CSI之间的差异与停止窗口值进行比较。如果差值大于停止窗口值，则从服务到客户端的消息传输被关闭。客户端在处理消息时继续发送CSI确认。一旦差异低于启动窗口值，则将消息传送到客户端就被打开。

摘要： A method and system for providing remote access to multi-channel audio by periodically polling channels of audio produced by, e.g., an application program by calling an Application Programming Interface (API). A method performs the polling to retrieve audio data from multiple channels and to mix the multiple channels into a mixed multichannel audio that is communicated to a remote computing device. The method transmits a sample minimum duration of audio data retrieved from all channels during at polling interval to provide low latency transmission of audio to remotely connected computing devices.

摘要： Systems and methods for providing a collaborative browsing capability. A web browser service may be collaboratively browsed by plural client computing devices at an enumerated URL in a collaborative browsing (co-browsing) session. A request made by a web browser in the session may be intercepted by a co-browsing service and forwarded to the web browser service. A response to the request is received by the co-browsing service and communicated all web browsers participating in the co-browsing session. For configured web browsers, a view associated with web browser service may be translated into client computing device specific presentation data for display.
