  • Publication number: 20180285579
    Abstract: Disclosed are methods and printer drivers for printing confidential documents. The method includes receiving a document for printing via an application running on a computing device. Then, it is determined whether received document is a confidential document based on at least one of: pre-defined methods and keywords. Then, the user is enforced to use a secure print mode and further invokes one or more security features, based on the determination. Then, the user is prompted to enter a passcode at the computing device for enforcing the secure print mode for the confidential document. A job request including the selected document and command parameters corresponding to the security features is sent to a multi-function device (MFD). The multi-function device enforces the security features for the received job request and prints the document as a secure print based on the passcode entered by the user at the multi-function device.

  • Patent number: 8532070
    Abstract: A method and apparatus for handoff of a wireless client from a first network device to a second network device in a wired network are disclosed. In one embodiment, the method includes receiving data from a new wireless client at the second network device and transmitting a request for a route update for the new wireless client to the wired network. Prior to network convergence for the route update, data traffic for the new wireless client is received from the first network device and forwarded to the new wireless client. Context information for the new wireless client is transmitted from the second network device to other network devices in a proximity group of the second network device.

  • Patent number: 8503445
    Abstract: Bridge domain communication methods and devices are presented for efficiently communicating information in a bridge domain based upon group indications and source indications. Packets with a source and destination indication are received. A bridge domain communication process is performed at the bridge level wherein a packet is selected for forwarding based upon a source and group indication. For example, a determination is made if a particular bridge domain corresponds to the group destination indication in the received packet. The source indication in the packet is compared with a tracked source designation indication. Output ports associated with the tracked source designation indication are identified if the tracked source designation indication matches the received source indication. The communication packet is forwarded on identified ports.

  • Patent number: 8320567
    Abstract: In one embodiment, a method for processing encrypted wireless station data at a network device includes receiving from an access point, one or more frames comprising wireless station data fragmented into a plurality of encrypted protocol data units. The frames are configured to identify the encrypted protocol units associated with the wireless station data. The method further includes decrypting the encrypted protocol data units and forwarding the wireless station data. An apparatus for processing encrypted wireless station data, a method for transmitting encrypted multicast data for a wireless client, and a method for processing encrypted wireless station data at an access point are also disclosed.

  • Patent number: 8040884
    Abstract: A method, system, computer program product and apparatus are presented to enable a L2 network device, such as a bridge or switch, to control the flow of a multicast data stream to a connected router in response to control messages received from the router by the L2 network device. By controlling the flow of multicast data streams in this manner, there will be a corresponding reduction in wasted bandwidth due to unnecessary transmission of these multicast data streams and a reduction in processing overhead by the router due to analysis and dropping of unnecessary multicast frames. In one aspect of the present invention, the router can generate the control messages in response to receiving a data frame in a multicast data stream from the L2 network device.
