The BSD Packet Filter: A New Architecture for User-level Packet Capture
, 1992
"... Many versions of Unix provide facilities for user-level packet capture, making possible the use of general purpose workstations for network monitoring. Because network monitors run as user-level processes, packets must be copied across the kernel/user-space protection boundary. This copying can be m ..."

The original Unix packet filter was designed around a stack-based filter evaluator that performs sub-optimally on current RISC CPUs. The BSD Packet Filter (BPF) uses a new, registerbased

On the Effectiveness of Route-Based Packet Filtering for Distributed DoS Attack Prevention in Power-Law Internets
- In Proc. ACM SIGCOMM
, 2001
"... Denial of service (DoS) attack on the Internet has become a pressing problem. In this paper, we describe and evaluate route-based distributed packet filtering (DPF), a novel approach to distributed DoS (DDoS) attack prevention. We show that DPF achieves proactiveness and scalability, and we show tha ..."

Ffpf: Fairly fast packet filters
- In Proceedings of OSDI’04
, 2004
"... FFPF is a network monitoring framework designed for three things: speed (handling high link rates), scalability (ability to handle multiple applications) and flexibility. Multiple applications that need to access overlapping sets of packets may share their packet buffers, thus avoiding a packet copy ..."

Flexibility is achieved by allowing expressions written in different languages to be connected to form complex processing graphs (not unlike UNIX

Face Detection Using Quantized Skin Color Regions Merging and Wavelet Packet Analysis
, 1999

In this paper, a novel scheme for human faces detection in color images under nonconstrained scene conditions, such as the presence of a complex background and uncontrolled il ..."

A merging stage is then iteratively performed on the set of homogeneous skin color regions in the color quantized
