    Abstract: Systems and methods for multi-links software-defined wide area network (SD-WAN) using phone mobile hotspots include a network device that receives, from a client, a request to establish a connection with a data source. The network device may select, responsive to receiving the request, a connection between the network device and one of the first registered cellular device or the second registered cellular device via which the network device is to transmit network traffic corresponding to the request, the first registered cellular device and the second registered cellular device registered with the network device and having a respective cellular connection. The network device may transmit network traffic corresponding to the request from the client via the connection to the data source.

    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: Disclosed embodiments process network traffic according to user feedback. At least one intermediary between a client and a server on a network may process network traffic of a session established between the client and the server. The at least one intermediary may intercept a message from the client identifying a level of quality of experience (QoE) indicated by a user based on the network traffic. The at least one intermediary may determine, in response to the intercepted message, that the level of the QoE is below a threshold, and a predefined action to improve a condition of the network causing the identified level of QoE. The at least one intermediary may change, according to the determination, the processing of the network traffic by taking the predefined action.

    Abstract: Embodiments of the present disclosure describe a system and method for dynamically duplicating network packets onto a reliable link. Network devices can be connected by a primary link and by a secondary link. As the network quality of the first link degrades, the system can adaptively duplicate network packets onto the second link. As a high priority link, the secondary link can have less total bandwidth when compared to the primary link. Accordingly, all the traffic traversing the primary link may not be able to be duplicated onto the secondary link to preserve network reliability when the quality of the first link degrades. The present solution can effectively manage the bandwidth of the secondary link and set duplication rates that control the duplication of the packets onto the secondary link.

    Abstract: The present invention is directed towards systems and methods for providing classification of an encrypted network packet for performing QoS and acceleration techniques. Encrypted packets may be classified by a first classifier at a first portion of a network stack of a device as corresponding to a first predetermined application, and an application identifier may be included with the packet. In some embodiments, the packets may be decrypted in an order dependent on a first classification of the encrypted network packet. After decryption, packets may be reclassified as corresponding to a second predetermined application by a second classifier operating at a second portion of a network stack of the device above the first portion. Thus, network performance may be enhanced and optimized by providing QoS and acceleration engines with packet- or data-specific information corresponding to the application, while avoiding inefficiencies due to a lack of prioritization of decryption.

    Abstract translation: 本发明涉及用于提供用于执行QoS和加速技术的加密网络分组的分类的系统和方法。 加密分组可以由与第一预定应用相对应的设备的网络堆栈的第一部分处的第一分类器分类，并且应用标识符可以包括在分组中。 在一些实施例中，分组可以以取决于加密网络分组的第一分类的顺序被解密。 在解密之后，可以通过在第一部分上方的设备的网络堆栈的第二部分操作的第二分类器将分组重新分类为对应于第二预定应用。 因此，可以通过向QoS和加速引擎提供与应用相对应的分组或数据特定信息，同时避免由于缺乏解密优先级而导致的低效率，可以增强和优化网络性能。
