  • Patent number: 10110604
    Abstract: The disclosure includes a sandbox technology based webpage browsing method and device. A method comprises receiving an instruction for webpage browsing in a sandbox. Upon receiving the instruction, a framework process is started outside the sandbox to process an operation incurred in the framework process outside the sandbox, wherein the framework process is a first part implemented by a browser. A browser process created by the framework process is intercepted, wherein the browser process is a second part implemented by the browser. The browser process is put into the sandbox to save a webpage access result in a specified directory in the sandbox or to run a script in the webpage in a virtual environment of the sandbox.

  • Patent number: 9699189
    Abstract: The invention discloses a sandbox technology based webpage browsing method and device. The method comprises: upon receiving an instruction for webpage browsing in a sandbox, starting a framework process outside the sandbox, so that an operation incurred in the framework process is processed outside the sandbox; intercepting a browser process created by the framework process and putting the browser process into the sandbox, so that a webpage access result is saved in a specified directory in the sandbox, and/or a script in the webpage runs in a virtual environment of the sandbox. The present invention not only ensures the convenience of user operations, but also meets the security requirement for webpage access.

  • Patent number: 7327733
    Abstract: Disclosed is a flushing method with separated sets for type 5 Link State Advertisement (LSA) in the Open Shortest Path First (OSPF) protocol. All LSAs originated in a network device are separated into S sets with a mapping method in advance. Only one set of LSAs are flushed at first; then another set of LSAs are flushed in order at a flushing interval. The method reduces the instantaneous traffic impact on a network by the LSAs greatly, so the network keeps a low level load. Furthermore, the method guarantees that all LSAs are flushed once every network flush interval, so the OSPF protocol can be implemented normally.
