  • Patent number: 10686885
    Abstract: The present disclosure relates to methods and systems for managing a guest virtual machine executing within a virtualized environment. A daemon is established on a guest virtual machine executing within a virtualized environment. The daemon is configured to communicate with a management service virtual machine executing within the virtualized environment. The daemon receives, from the management service virtual machine via an application layer protocol, a request identifying an action type of a plurality of predetermined action types. The daemon identifies the action type of the plurality of predetermined action types from the received request and performs an action corresponding to the identified action type. In some implementations, the application layer protocol is one of Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS).

  • Patent number: 9600313
    Abstract: This disclosure describes a system for Single Root I/O Virtualization (SR-IOV) pass-thru for network packet processing via a virtualized environment of a device. The system includes a device comprising a virtualized environment and a plurality of virtual machines having a virtual network interface for receiving and transmitting network packets. A driver for the physical network interface of the device creates a plurality of virtual devices corresponding to the physical network interface, which appear as a Peripheral Component Interconnect (PCI) device to the virtualized environment. A virtual device of the plurality of virtual devices is assigned via the virtualized environment to each virtual machine of the plurality of virtual machines. The virtual machine uses the virtual device assigned to the virtual machine, to receive and transmit network packets via the physical network interface of the device.

  • Patent number: 9215212
    Abstract: The present invention is directed towards systems and methods for generating a representation a plurality of learned rules from a learning engine of an application firewall. The representation may be generated based on a history of URL communications with a web server. A learning engine of an application firewall may determine a plurality of learned rules based on a history of URL communications with a web server. Each of the plurality of learned rules mat be assigned a URL string. A visualizer can categorize a subset of the plurality of learned rules under a first check type of a plurality of check types. The visualizer may further generate a tree representation of URL strings of the subset of learned rules. Each node of the tree corresponds to a segment of the URL strings identified based on a delimiter for the URL strings.

  • Patent number: 8819561
    Abstract: The present invention is directed towards systems and methods of providing management of network services provided by an intermediary device managing traffic between a plurality of clients and servers. The intermediary device may include one or more virtual servers managing a plurality of services. A user can invoke a visualizer tool of the intermediary device to identify a configuration and an operational status of the virtual servers and services managed by the virtual servers. The visualizer tool may also determine from the configuration two or more services having a common set of configuration properties and managed by a first virtual server. The visualizer tool may establish a service container comprising these services. The visualizer tool may display via an interface a graphical representation of the configuration and the operational status of the first virtual server and the service container identifying the common set of configuration properties of these services.

  • Patent number: 8812714
    Abstract: The present solution is directed towards embodiments of a feature generally referred to as Application Templates or AppTemplates, which allows a administrator of an intermediary, such as an appliance, to configure and manage settings per application on a basis of a subset of application network traffic. Once configured, the application settings can be exported in a file called the Application Template, and imported into other intermediary systems. The Application Template includes the settings for the application as configured via the intermediary.
