First Claim
Patent Images
1. A policy-based network flow management method, comprising:
- determining whether network traffic received from a requester satisfies a policy condition that is configured based at least in part upon one of a source network condition associated with said requester and multi-layer information associated with said network traffic; and
responsive to said determining, applying a policy action corresponding to said policy condition, said policy action including at least one of dropping said network traffic, forwarding said network traffic, redirecting said network traffic, and queuing said network traffic.

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.

17. A network node, comprising:
-
means for maintaining at least one pointer table associated with a plurality of policy application servers, wherein said policy application servers are grouped into clusters based on an access control list, said policy application servers operating to apply one or more policy actions with respect to network traffic generated by content requesters; means for polling said policy application servers to determine status of said policy application servers; and means for updating said at least one pointer table based upon said polling. - View Dependent Claims (18, 19, 20, 21, 22)
