Beeline: Enforcing application-layer policies in eBPF
The post argues that although Layer 7 protocols are often difficult to parse, enforcing Layer 7 policies is usually simple enough that Beeline can remove the service proxy from the critical path for 89% of real-world policies.
MAIN POINTS
- L7 protocols are generally complex to parse.
- Enforcing L7 policies is usually much simpler than parsing them.
- Beeline can bypass the service proxy for most policy enforcement.
- This applies to 89% of observed real-world L7 policies.
TAKEAWAYS
- Parsing complexity does not necessarily mean enforcement complexity.
- Most L7 policy checks can be handled without proxying traffic.
- Removing the proxy from the critical path can improve efficiency.
- The claim is supported by a large share of real-world policy cases.
