Correctness and Performance for Stateful Chained Network Functions

on YouTube ↗21m

" summary

Presents CHC, an NFV framework that uses an external state store plus state-management algorithms and metadata tracking to maintain correct chain-wide state for stateful chained network functions during dynamic scaling and failures. Evaluates CHC on performance, reporting about 10 Gbps per-NF throughput and a 0.6 μs median per-packet latency increase while ensuring correctness across the chain.
