    摘要: In a messaging system interfaced through the Internet, a method for processing a message from a sender and intended for delivery to at least one recipient, which sender is interfaced to the Internet through a sender server and which recipient is interfaced to the Internet through a recipient server, where the message includes at least recipient information and message body, is disclosed. The method includes testing the recipient information by establishing a temporary test connection through the Internet from the sender server to the recipient server, before relying on the recipient information for sending the message, so as to provide an indication of deliverability of the message to the recipient without using an SMTP VRFY command.

    摘要: A method and apparatus that secures a dynamic virtualized network is described. In an exemplary embodiment, a device learns a current network policy of the dynamic virtualized network, where the dynamic virtualized network is a virtualized layer 2 network that is overlaid on a layer 3 physical network. In addition, the current network policy includes multiple network policy elements, where each of the multiple network policy elements identifies an authorized endpoint in the dynamic virtualized network. Furthermore, the layer 3 physical network includes multiple network access devices. The device further determines a network security policy for the dynamic virtualized network from the current network policy. The network security policy includes one or more second network policy elements that are a different network policy element than one of the multiple network policy elements of the current network policy. In addition, each of the one or more second network policy network elements adds an additional policy on how network traffic is processed in the dynamic virtualized network by a port of one of the plurality of network access devices. The device further applies the network security policy to each network access device that is affected by the network security policy.

    摘要: A method and apparatus that determines a plurality of matching policies for a segment of a dynamic virtualized network is described. A device retrieves a virtual network identifier of the segment, where the virtual network identifier includes a plurality of bits and a plurality of subnets and each of the plurality of subnets is a different subset of the plurality of bits. In addition, the dynamic virtualized network is a virtualized layer 2 network that is overlaid on a layer 3 physical network, where the layer 3 physical network includes a plurality of network access devices, and the segment includes a plurality of endpoints. The device further determines the plurality of matching policies for the segment from the plurality of subnets of the virtual network identifier, where each of the plurality of subnets corresponds to one of the plurality of matching policies. The device additionally applies the plurality of matching policies to each network access device that corresponds to one of the plurality of matching endpoints.

    摘要: A method and apparatus of a device that dynamically changes how management data is managed in response to events detected in a network system is described. In an exemplary embodiment, the device detects an event occurring in the network system. The device further determines if the event triggers a system change in how the management data is reported on one or more of the managed nodes. If the event notification does trigger the system change, for each of the one or more of the managed nodes, the device determines a command for that manage node that represents a specific change in how frequent the management data is reported to the network management system. In addition, the device sends the command to that managed node, where the agent applies the command to the managed node and the applied command implements the specific change in how frequent the management data is reported to the network management system.
