  • Publication number: 20090304001
    Abstract: A method is described that entails assigning a source network address to an outbound packet, associating the outbound packet with a network service and identifying a first network interface associated with the network service. The method further entails inquiring into and confirming that the first network interface is associated with the source network address. The method further entails constructing a search key from an identifier of the first network interface and the outbound packet's destination address. The method further entails submitting the search key to a routing function, the routing function providing the outbound packet's next hop address. The method further entails transmitting the outbound packet to a node identified by the next hop address from the network interface.

  • Publication number: 20090227274
    Abstract: A method for configuring a device includes receiving a first configuration profile comprising a first configuration and a first certificate and a second certificate, verifying the first configuration profile with the first certificate, receiving a user input indicating to accept the first configuration profile, configuring the device according to the first configuration, receiving a second configuration profile comprising a second configuration, verifying the second configuration profile with the second certificate and updating the device according to the second configuration, wherein the user is unaware of the updating.

  • Publication number: 20090006635
    Abstract: Systems and methods relating to managing network addresses. In one implementation, a method is provided. The method includes sending a first request to use a particular network address, sending one or more second requests for respective hardware addresses corresponding to network addresses of one or more network address leases. When a hardware address corresponding to a particular network address lease is received in response to one of the one or more second requests and an acknowledgement of the first request to use the network address is not received determining whether the network address identified by the lease is the same as the network address in the first request, and when the network address is not the same, sending a third request to use the identified network address corresponding to the lease.

  • Publication number: 20090006600
    Abstract: Methods, computer program products, systems and data structures for generating a signature for a network are described. A network signature may include, for example, network information associated with a network (e.g., IP address, MAC address, domain name, DNS name, routing information, phone number, etc.). A signature of a network that has previously been created can be stored to enable identification of the network in the future and to record parameters, settings, properties and attributes previously used for that network.

  • Publication number: 20070050645
    Abstract: One embodiment of the present invention provides a system that wakes up a sleeping target system located on a target LAN (Local Area Network) from a remote system located on a remote LAN. Note that, since the sleeping target system is in a sleep state, it receives packets of a lower-layer protocol which cannot be used by the remote system to directly send packets to the sleeping target system. During operation, the remote system creates a wake-up packet. The remote system then uses a second protocol to send the wake-up packet to a relay agent located on the target LAN. Note that using the upper-layer protocol enables the remote system to communicate with the relay agent even though they are on different LANs. Upon receiving the first wake-up packet, the relay agent uses the lower-layer protocol to send a second wake-up packet to the sleeping target system, which causes the sleeping target system to wake up.
