There is a growing demand for network devices capable of examining the content of data packets in order to improve network security and provide application-specific services. Most...
—Regular expression matching has become a critical yet challenging technique in content-aware network processing, such as application identification and deep inspection. To meet ...
We present an approach to building multicast services at the network layer using unicast forwarding and two additional building blocks: (i) ephemeral state probes, i.e. extremely l...
Deep Packet Inspection (DPI) refers to examining both packet header and payload to look for predefined patterns, which is essential for network security, intrusion detection and c...
Modern deep packet inspection systems use regular expressions to define various patterns of interest in network data streams. Deterministic Finite Automata (DFA) are commonly used...
