  • Patent number: 10560550
    Abstract: A first network device may establish connectivity with a second network device. The first network device may determine information that identifies a cluster identifier based on establishing connectivity with the second network device. The first network device may compare a first software version of the first network device and a second software version of the second network device. The first network device may selectively obtain and install a system image of the second network device based on comparing the first software version and the second software version. The first network device may receive, from the second network device, configuration information and user session information based on selectively obtaining the system image. The first network device and the second network device may form a high-availability cluster.

  • Patent number: 9130887
    Abstract: A system is provided for forwarding packets with hierarchically structured variable-length identifiers (HSVLIs) over Ethernet. The system receives an Ethernet-encapsulated registration message from a content server, which includes a packet containing an HSVLI. A destination MAC of the registration message is an Ethernet group MAC address. The system then creates an entry in a forwarding information base corresponding to the HSVLI indicating a MAC address of the content server and a port on which the registration message is received. The system receives an interest packet from a client which includes the HSVLI. The packet has the Ethernet group MAC address as its destination MAC address and the client's MAC address as its source MAC address. The system forwards the interest packet to the content server, which has the content server's MAC address as its destination MAC address and a local switch's MAC address as its source MAC address.

  • Patent number: 8976968
    Abstract: Intercepting a secure communication session includes distributing a key from a key distribution point to establish a secure communication session between a first endpoint and a second endpoint. A secure channel is established between the key distribution point and an intercepting point. The intercepting endpoint may be determined to be authorized to intercept the secure communication session. The key is provided to the intercepting endpoint only if the intercepting endpoint is authorized to intercept the secure communication session, where the key provides the intercepting endpoint with access to intercept the secure communication session.

  • Patent number: 6219799
    Abstract: A system and method for providing redundant access to a network-based storage medium. The storage medium is divided into at least two partitions and two computers are configured as network servers, one each of the computers acting as a server for one each of the partitions. Each of the computers is assigned a unique name to identify it to the network. A first one of the computers supports multiple network names. When the other computer fails or goes off-line the first computer is configured to respond to both the first name and the second name, and to act as a network server for both partitions. The network can thus access the partition served by the second computer even though the second computer is off-line. When the second computer returns on-line, the first computer is re-configured to its initial configuration.
