  • Patent number: 7636940
    Abstract: A firewall protects an Ethernet network from a first larger network, e.g., the Internet. A first server on the Ethernet network stores an encrypted private key, decrypts the private key using a passphrase, and communicates with clients on the first network using the private key. A second server on the Ethernet network determines whether an intrusion has occurred from the first network into the first server and provides the passphrase to the first server only when no intrusion has occurred from the first network into the first server. The invention can be realized in apparatuses, methods, and/or instruction sets.

  • Publication number: 20080008302
    Abstract: A method for call-logging is provided. The method includes monitoring packet headers transmitted from and received by a port associated with a computer device. Next, the port number of the computer device is determined. Subsequently, an identification is made as to whether a communication channel for passing data has been established. If the communication channel has been established and the port number is determined to be associated with an H.323 application then the method moves on to record call start time. When the communication channel is terminated the method proceeds to record the call end time. Thereafter, the call duration is determined by subtracting the call start time from the call end time. After that, a calendar application is invoked and the call duration is logged into the calendar application.

  • Patent number: 7263071
    Abstract: A communication protocol, and a method and system of communication exchange between systems over a communication network includes establishing a connection between a first system and a second system. Data is formatted by the first system into an IP datagram with an IP header and one of a TCP and a UDP header. A connectionless TCP/IP header is constructed to add to the formatted data. The connectionless TCP/IP header includes a pre-defined identifying value in a designated field, and a checksum to validate that a connectionless TCP/IP header has been identified. The formatted data having the connectionless TCP/IP header is transmitted from the first system to the second system, and the pre-defined identifying value in the designated field is verified to identify the connectionless TCP/IP header. The connectionless TCP/IP header is then removed from the IP datagram, and the IP datagram is processed.
