tooling to provide: Event monitoring with metadata: When a packet is dropped, the tool doesn’t just report the source and destination IP of the packet, the tool provides the full label information of both the the sender and receiver among a lot of other information. Policy decision tracing: Why is a packet being dropped or a request rejected. The policy tracing framework allows to trace the policy decision viewing security policies, and configuring network monitoring behavior. Linux Kernel BPF Berkeley Packet Filter (BPF) is a Linux kernel bytecode interpreter originally introduced to filter network packets

This means that traffic will look like it is coming from outside of the cluster to the receiving

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
