Maestro: Automatic Parallelization of Software Network Functions

Maestro is a tool that analyzes a sequential implementation of a Software Network Function (NF) and automatically generates an enhanced parallel version that carefully configures the NICs RSS mechanism to distribute traffic across cores, while preserving semantics. When possible, Maestro orchestrates a shared-nothing architecture, with each core operating independently, without requiring shared memory coordination, maximizing performance. Otherwise, Maestro choreographs a fine-grained read-write locking mechanism that optimizes operation for typical Internet traffic.
