  • System and Method for Managing Network Flows Based on Policy Criteria
    Publication number: 20090100506
    Abstract: A policy-based network flow management system and method. In one embodiment, various policy conditions are configured based at least in part upon source network conditions and multi-layer information (e.g., Layer 2, Layer 3, and so on) associated with network traffic. Where network traffic from a content requester is determined to satisfy a policy condition, a corresponding policy action is effectuated, e.g., dropping the network traffic, forwarding the network traffic, redirecting the network traffic, or queuing the network traffic.

  • Port re-enabling by monitoring link status
    Patent number: 7417953
    Abstract: The present invention features embodiments of automatically re-enabling a disabled port or physical media interface by monitoring the link status of the physical layer interface. Any change in the link status automatically re-enables a previously disabled port, thereby permitting data coming in through the previously disabled port to be admitted into the switch and automatically forwarded or routed/switched, without the network administrator manually issuing any commands to manually re-enable the port.
