    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.

    Abstract: A virtual desktop server include 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, and a processor coupled to the application framework and to the native RTC engine. The processor redirects original application program interfaces (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 to be redirected. The processor receives from a client computing device capabilities of the client computing device to execute the redirected portion of the real-time media application. The processor switches to a fallback mode if the client computing device has limited capabilities.

    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: 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: Described embodiments provide systems and methods for selectively encrypting and decrypting portions of a network flow by intermediary devices. A first device may identify a protocol used by a network flow traversing the first device via one or more packets of the protocol. The first device may determine that a level of encryption for the network flow meets a predetermined threshold. The first device may receive networks packets to be communicated between a sender and a receiver. The packets may include a first portion that is encrypted and a second portion that has clear text information. The first device may encrypt the second portion of the one or more packets. The first device may forward the network packets with the first portion and the encrypted second portion via a tunnel to a second device for decryption of the encrypted second portion for forwarding to the receiver.
