Abstract: 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.

Abstract: 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.
