  • Virtual router redundancy for server virtualization
    Patent number: 9094334
    Abstract: A solution for virtual router redundancy for server virtualization includes, at a network device configured as a backup router of a virtual router, examining a packet stored in a memory of the network device. Responsive to the examining, the network device determines whether to forward the packet via a network towards a destination or to send the packet via the network to a master router of the virtual router for forwarding of the packet, by the master router, towards the destination.
    Type: Grant

  • Techniques for preventing attacks on computer systems and networks
    Patent number: 8509106
    Abstract: Techniques for detecting and responding to attacks on computer and network systems including denial-of-service (DoS) attacks. A packet is classified as potentially being an attack packet if it matches an access control list (ACL) specifying one or more conditions. One or more actions may be performed responsive to packets identified as potential attack packets. These actions may include dropping packets identified as potential attack packets for a period of time, rate limiting a port over which the potential attack packets are received for a period of time, and other actions.
