The method includes flushing the second set of records of the database table in one or more persistent storage devices and querying of the plurality of records of the database table. The method includes inferring one or more complex events from transition of a plurality of states.

Abstract: The security of network connections on a computing device is protected by detecting and preventing compromise of the network connections, including man-in-the-middle (MITM) attacks. Active probing and other methods are used to detect the attacks. Responses to detection include one or more of displaying a warning to a user of the computing device, providing an option to disconnect the network connection, blocking the network connection, switching to a different network connection, applying a policy, and sending anomaly information to a security server.

Abstract: Dynamic subscriber interfaces in a network device are provided. An input port receives data units from multiple subscribers. A primary interface extracts source identifiers from headers associated with the received data units and creates dynamic subscriber interfaces to allocate network device resources to each of the multiple subscribers based on the extracted source identifiers.

Abstract: A method and device to manage addresses in a network includes receiving a request for a network address from a client computer at a proxy computer, relaying the request to an address server, receiving an address offer message from the address server at the proxy computer, storing an server identifier of the address server from the offer message, replacing the server identifier of the address server in the offer message with an address identifier of the proxy computer to produce an altered offer message, and sending the altered offer message to the client computer.

Abstract: Techniques are described for dynamically configuring an interface in a network service provider. The techniques allow dynamic configuration of, for example, a dual stacked interface that includes both Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4) on the same layer 2 link. In this way, a customer network having an existing IPv4 connection to a network service provider will be able to run both IPv4 and IPv6 over the same interface. A network device within the network service provider may receive a control packet from a subscriber device. The packet may be received on an ATM hybrid permanent virtual circuit (PVC) that supports multiple interface columns. The network device is capable of auto-sensing multiple packet protocols and may dynamically create multiple interface columns over the same ATM interface based on the encapsulation type of the received packets.

Abstract: Multiple subscriber devices are connected to a network device via one or more network switches. The network device transmits multicast traffic to the subscriber devices. In particular, the network device may receive membership requests for a multicast group from the subscriber devices via the network switch on a first interface, i.e., a mapping interface. The network device sends a multicast stream associated with the multicast group to the network switch on a second interface, i.e. an outgoing interface (OIF). Upon receiving a membership request, the network device maps the membership request to an OIF dedicated to the multicast group. In this way, when multiple subscriber devices connected to the same switch request the same multicast stream, each membership request will map to the same OIF. The network device sends one copy of the multicast stream to the network switch on the dedicated OIF.

Abstract: A network device seamlessly handles multicast traffic flow between virtual private networks (VPNs) and content providers located external to the VPNs. For example, the network device, such as a router, comprises an interface card and a forwarding component. The forwarding component maintains forwarding data for a public network and forwarding data for the virtual private network. The interface card receives a multicast packet from a virtual private network destined for a multicast content provider external to the virtual private network. When forwarding the multicast packet, the forwarding component bypasses the forwarding data for the public network and forwards the multicast packet to the multicast content provider in accordance with the forwarding data for the public network.
