  • Patent number: 9912663
    Abstract: Methods and systems of communicating with secure endpoints included within a secured network from a mobile device external to the secured network is disclosed. The method includes initiating a VPN-based secure connection to a VPN appliance, and initializing a stealth-based service on the mobile device. The method further includes transmitting user credential information from the mobile device to a VDR broker via the VPN appliance, and receiving status information from the VDR broker identifying a VDR associated with the mobile device and providing a connected status. The method also includes communicating with one or more secure endpoints within the secured network via a VPN connection to the VDR via the VPN appliance and through the VDR to the one or more secure endpoints within a community of interest based on the user credential information transmitted to the VDR broker.

  • Patent number: 6832376
    Abstract: A method and apparatus for reusing a thread for different programmed operations are provided in various embodiments. In one embodiment, different application operations are defined as subclasses of a thread operation class, and a thread is implemented with a thread class. In one embodiment, the application operations can be queued to the thread for scheduled execution using the thread. In another embodiment, a first application operation can start a thread and be executed therewith, while a second application operation can attach to the thread for execution.

  • Patent number: 6687729
    Abstract: A system and method for managing a pool of threads for executing thread operations. A thread pool is instantiated which includes a plurality of threads, and a work queue having program controllable states is instantiated. Thread operations are queued to the work queue when the work queue is in a running or suspended state, and when the work queue is in a stopped state requests to queue thread operations are denied. The work queue supports controlled allocation of thread resources to a variety of thread operations.
