Multitenant In-Network Acceleration with SwitchVM

on YouTube ↗17m

" summary

Proposes SwitchVM: a sandboxed VM that runs tenant Turing-complete DPFs on programmable switches, implemented as an interpreter built in P4 on Intel Tofino. Claims: strong isolation, zero-overhead runtime programmability, and two orders of magnitude more in-switch programs than prior work; prototype supports up to thirty thousand tenants and uses four execution units (four-wide ISA per packet pass) to run load‑aware load balancing, Paxos acceleration and a KV cache successfully at line rate.
