Presto: A match-action TCP stack for the terabit era
Presto is a guest post describing how the system builds on the RMT architecture behind programmable switches while addressing the architecture’s main constraints to improve switch programmability and practicality.
MAIN POINTS
- Presto leverages the RMT architecture as the foundation for programmable switches.
- It focuses on overcoming the primary limitations inherent in RMT-based designs.
- The post frames Presto as an architectural response to switch programmability challenges.
- Its emphasis is on making programmable switching more workable within RMT constraints.
TAKEAWAYS
- RMT remains a key architecture for programmable switch design.
- Practical switch systems must account for hardware constraints, not just programmability goals.
- Presto is positioned as a solution that adapts to those limitations.
- Understanding RMT’s bottlenecks is essential to evaluating switch architectures.
