Techniques and algorithms to forward packets have been a topic of discussion since the eighties. In this podcast, I chat with Mario Baldi about forwarding. Mario has also his own blog at https://blog.baldi.info/
We informally cover:
- Layer 2 vs. layer 3 forwarding
- ACLs processing
- Binary vs. ternary matches
- Binary hash table forwarding
- Ternary LPM (Longest Prefix Match) forwarding
- Combining forwarding with ACLs
- Flow cache based forwarding
