  • Patent number: 8612754
    Abstract: A method provides data loss protection of sensitive data using digital fingerprinting. The method includes assigning a security level to each document of a plurality of documents associated with a data loss protection server, and storing the plurality of documents in a digital asset management server, wherein only a single copy of each document of plurality of documents is stored in the digital asset management server. The method also includes sending a query to the digital asset management server from the data loss protection server, and receiving a query response by the data loss protection server from the digital asset management server, the query response including at least one document file. The method further includes creating a digital fingerprint of the at least one document file by the data loss protection server.

  • Patent number: 7778268
    Abstract: Systems and methods for redundancy in a network device are disclosed. An exemplary network device comprises: a plurality of data forwarding elements (DFEs); and a redundant control plane. The redundant control plane comprises: an active control processor for configuring forwarding operation of each of the DFEs; an active layer-2 switch coupled to the active control processor and to each of the DFEs; a standby control processor; and a standby layer-2 switch coupled to the standby control processor and to each of the DFEs. The active control processor is programmed in a full-mesh so that the active control processor is in communication with each of the DFEs. The standby control processor is programmed in a full-mesh so that the standby control processor is in communication with each of the DFEs.

  • Publication number: 20080311615
    Abstract: A method for the separation and simultaneous determination of urinary D- and L-lactic acid enantiomers by high performance liquid chromatography tandem mass spectrometry (HPLC/MS/MS). The chiral separation was done using a chirobiotic teicoplanin aglycone column varying mobile phase parameters such as the acetic acid/triethylamine content and the aqueous/organic ratio.

  • Publication number: 20070104105
    Abstract: Systems and methods for determining lost packets for real-time transport protocol (RTP) data flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor. The processor is configured by the software to perform the steps of determining a sequence number of a received RTP data packet within said RTP data flow, storing said determined sequence number, calculating whether said determined sequence number sequentially falls within a predetermined numerical order, and if said sequence number of said received RTP data packet does not sequentially fall within said numerical order, storing said sequence number as a missed RTP data packet.

  • Publication number: 20060187927
    Abstract: A system and method for providing rapid rerouting of real-time transport protocol (RTP) multi-media flows is disclosed. Generally, a first endpoint is connected to a second endpoint, wherein the first endpoint comprises a transceiver, software stored within the first endpoint defining functions to be performed by the first endpoint, and a processor configured by the software. The processor is configured to perform the steps of, performing flow processing on a data packet received at a first endpoint, from a second endpoint, removing a multi-protocol label switching (MPLS) tag from the data packet, translating a source address and destination address of the data packet, and determining a forwarding destination if more than one destination address of the data packet is provided.

  • Publication number: 20060005243
    Abstract: Methods, systems, and products are disclosed for detecting an intrusion to a communications network. One embodiment describes a peripheral card having a communications portion and a processor. The communications portion has only a capability for receiving data packets via the communications network. The communications portion lacks capability of transmitting the data packets via the communications network. The processor manages the communications portion, and the communications portion reduces intrusion of the communications network.

  • Patent number: 3974026
    Abstract: The belt press is constructed with a rotatable cylinder, a guide belt to confine the material between the belt and cylinder, and a press member for pressing the belt towards the cylinder to remove water from the confined material. The press member has a curved face slightly spaced from the belt as well as a pressure chamber which delivers a pressurized medium, such as water or air, against the belt over the face of the press member.
