  • Detection and mitigation of rapidly propagating threats from P2P, IRC and gaming
    Patent number: 8117657
    Abstract: A network switch detects at least two simultaneous connections on a single network port. The simultaneous connections use different protocols despite using the same port. The network switch mirrors network traffic associated with the simultaneous connections to a security management device on the network. The security management device then determines a source or destination of the network traffic.

  • Enforcing host routing settings on a network device
    Patent number: 8055800
    Abstract: A method and system for enforcing host routing settings in a network device comprises network devices having enforcement logic for extracting host routing settings from a DHCP packet issued by a DHCP server to a DHCP client connecting to a network. The network devices generate enforcement rules based on the host routing settings and apply those rules to ports through which the DHCP client connects to the network. The enforcement rules include access control lists having one or more match conditions generated based on the host routing settings.

  • Frequency-table-based storage for network performance data
    Patent number: 7743136
    Abstract: A network services system (100) uses frequency tables (300) to store real-time network performance data such as delay, jitter, loss, loss burstiness, and mean opinion score (MOS) for a real-time communications protocol such as the Real Time Protocol (RTP).

  • Detection of load balanced links in internet protocol netwoks
    Patent number: 7426577
    Abstract: A system is provided that includes a memory 204 comprising a baseline topology 216; and a processor 208 that selects, from the baseline topology 216, first and second addresses associated with first and second routers 224 and 228, respectively, wherein the first router 224 has an associated first hop count relative to a selected node 200 and the second router 228 an associated higher second hop count relative to the selected node 200, transmit test packets having a time to live equal to or greater than the first hop count, receive responses associated with the test packets, and determine, based on the response, whether load balancing is in effect at the first router 224.
