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.

Systems and methods for managing streams of packets via intermediary devices

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.

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.

Auto tuning of hybrid WAN links by adaptive duplication of packets on alternate links

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.

The present invention is directed towards systems and methods for providing discovery of applications for classification of a network packet for performing QoS and acceleration techniques. Remote display protocol traffic associated with a new application not previously included in a list of predetermined applications may be parsed for application information, and the new application may be added to the application list. The remote display protocol traffic may then be classified according to the new application, and network performance may be enhanced and optimized by providing QoS and acceleration engines with packet- or data-specific information corresponding to the newly identified application.

Systems and methods for quality of service of ICA published applications

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.

Systems and methods for quality of service of encrypted network traffic

The present invention is directed towards systems and methods for providing multi-level classification of a network packet. In some embodiments, network performance may be enhanced and optimized by providing QoS and acceleration engines with packet- or data-specific information. In addition to source and destination IP addresses and port numbers, packet- or data-specific information can include direction of traffic (client to host or server; server or host to client; or both), Virtual LAN (VLAN) ID, source or destination application or associated application, service class, ICA priority, type of service, differentiated service code point (DSCP), or other information. Some or all of this information may be used to classify the network packet at a plurality of layers of a network stack, allowing for deep inspection of the packet and multiple levels of granularity of classification.

An exhaust driven turbofan to operates a generator, for generating electrical energy, which is stored in a battery until needed. An air blower is powered by energy from the battery, to generate pressurized air. The pressurized air passes into the piston chamber when the gas pedal is depressed, independent of the rotation of the crank shaft. An exhaust blower powered by the battery, sucks air from the piston chamber during the exhaust stroke, ensuring complete removal of the exhaust gasses. Valve overlap timing is no longer needed, eliminating the dwell time between intake and exhaust gasses. A non-ferrous wheel having ferrous portions is anchored in spaced relation about the outer periphery of the non-ferrous wheel, to assist the rotation of the crank shaft. At least one electromagnet is selectively energized to aid rotation of the non ferrous wheel. A diesel injector nozzle is positioned across the head of the combustion chamber for direct injection of diesel fuel as the piston power stroke approaches maximum extension. The diesel injector nozzle includes a sodium filled outer body to delay heating the fuel at the nozzle. Rotating bearings are disposed at every rotational part of the diesel engine.
