Demultiplexing using Dynamic Code Generation A new packet-filter system, DPF (Dynamic Packet Filters), that provides both the traditional flexibility of packet filters and the speed of hand- crafted demultiplexing demultiplexing routines. DPF filters run 10–50 times faster than the fastest packet filters reported in the literature. DPF’s performance is either equivalent to or, when it can exploit runtime information declarative packet-filter language that is aggressively optimized using dynamic code generation. — 1994 (read)DPF Fast, Flexible Message Demultiplexing using Dynamic Code Generation A new packet-filter
