    Abstract: A computing system includes a virtual desktop server and a client computing device. The virtual desktop server includes an application framework comprising a real-time media application to provide real-time communications (RTC), a native RTC engine to execute a portion of the real-time media application when received by the native RTC engine, and an API code redirection module. The API code redirection module redirects intercepted APIs of the real-time media application intended for the native RTC engine based on redirection code injected into the real-time media application so that the portion of the real-time media application is redirected. The client computing device includes a client RTC API engine communicating with the API code redirection module through a virtual channel to execute the redirected portion of the real-time media application.

    Abstract: A computing system includes a virtual desktop server and a client computing device. The virtual desktop server includes a real-time media application to provide real-time communications (RTC) for peer-to-peer networking, and a native RTC engine to execute a portion of the real-time media application when received by the native RTC engine. An API code redirection module redirects intercepted APIs of the real-time media application so that the portion of the real-time media application is redirected away from the native RTC engine to a client RTC engine in the client computing device. The portion of the real-time media application being redirected includes provisioning information directed to a remote media server. A network location service provides provisioning information directed to a nearby media server. The client RTC engine executes the redirected portion of the real-time media application, and selects the remote media server or the nearby media server based on network proximity to the client computing device.

    Abstract: Virtual application and desktop delivery may be optimized by supplying application metadata and user intent to the device between a client and a server hosting resources for the delivery. The data packets used to deliver the virtual application or desktop may be also tagged with references to the application. By supplying the metadata and tagging packets with the metadata, an intermediary network device may provide streams of data packets at the target QoS. In addition, the device may apply network resource allocation rules (e.g., firewalls and QoS configuration) for redirected content retrieved by the client out of band relative to a virtual channel such as the Internet. The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.

    Abstract: Described embodiments provide systems and methods for steering network traffic using dynamically generated configuration scripts. A first device may generate a configuration script for an application on the client for connecting with a server. The configuration script may specify the application to establish a direct connection or an indirect connection with the server. The first device may provide the configuration script to be invoked by the application to identify a first address to access the server based on a determination to establish the direct connection or the indirect connection. The first device may receive, from the client, an initiation request to connect with the server including the first address. The first device may determine second address by applying a routing policy to the first address. The first device may establish one of the direct connection or the indirect connection using the second address.

    Abstract: Described embodiments provide systems and method for intelligent path selection to reduce latency and maintain security. A client can request access to a server and multiple connections can be initiated to the requested destination, for example, a direct connection from a branch office and a backhauled connection through a data center. Traffic via the second connection can be controllable by application of at least one rule of the data center. A device can determine a delay in the exchange of data via the connections and a security level of the connections. The determination of the delay in the exchange of data via the another connection can be based on in part feedback about the application of the rule. The device can connect a client device to a server through one of the connections using the determination of the delay and the security level of the connection.
