Abstract
Embodiments are directed towards minimizing the impact flood attacks may have on packet traffic management performance. A packet traffic management device ('PTMD') may employ a data flow segment ('DFS') and control segment (“CS”). The CS may perform high-level control functions and per-flow policy enforcement for connection flows maintained at the DFS, while the DFS may perform statistics gathering, per-packet policy enforcement (e.g., packet address translations), or the like, on connection flows maintained at the DFS. The DFS may include high-speed flow caches and other high-speed components that may be comprised of high-performance computer memory. The impact of flood attacks may be reduced by protecting the high-speed flow caches from being consumed by flow control data associated with malicious and/or in-operative non-genuine network connections. In at least one of the various embodiments, flood control filters may be adaptively activated based on the condition and quality of network traffic received at PTMD.
