  • Patent number: 9191316
    Abstract: At a network device that forwards packets between compute devices and virtual storage area networks using Fiber Channel over Ethernet techniques, data is stored for a virtual fabric port of the network device identifying each of a plurality of virtual storage area networks. For each virtual storage area network, data is stored identifying each of a plurality of compute devices that are logged into the virtual storage area network via the network device. The network device forwards packets sent to the virtual fabric port of the network device from the plurality of compute devices to corresponding ones of the plurality of virtual storage area networks.

  • Patent number: 8464058
    Abstract: A password-based cryptographic method is effected between a first party with a specified identity and secret password and a second party with a master secret. During a registration phase, a long-term password-based public key is generated for the first party from its password and the master secret of the second party. Subsequently, to generate matching keys, asymmetric or symmetric, for the parties for a specific interaction, the first party generates short-term secret x, and computes a short-term password-based public key that requires for its computation direct knowledge of the first party's password and secrets x; the second party then transforms this short-term password-based public key into an clement X, complimentary to x, by using its master secret and at least a first-party-specific constituent of the first party's long-term password-based public key. The secret x and element X are then used to provide matching keys for the parties.

  • Publication number: 20120020217
    Abstract: Storing network flow information. Network packets comprising network internet protocol flow information is received at a network device, the network packets comprising an internet protocol header comprising internet protocol source and destination information pairs. The internet protocol source and destination information pairs are stored at a memory table of the network device. The internet protocol source and destination information pairs are made available for searching.

  • Publication number: 20110026529
    Abstract: A method and apparatus for processing a Dynamic Host Configuration Protocol (DHCP) packet in a trusted network are disclosed. The trusted network includes a plurality of trusted network devices and a trusted host. The DHCP packet is received at a network device of the trusted network. A port of the network device from which the DHCP packet was received is determined. An identifier associated with the port is determined. An option in the DHCP packet is marked by the network device using the identifier. The marked DHCP packet is transmitted along a forwarding path.
