Benchmarking DNSSEC Key Rollover Security Protocols (6644)
Technical Overview
Engineering breakdown of Benchmarking DNSSEC Key Rollover Security Protocols (6644). Bare-metal hardware performance requires isolated kernel parameters, deterministic interrupt handling, and cache-line alignment to achieve sub-microsecond latency variance. This article presents a reproducible methodology for measuring cryptographic operation throughput, validator convergence time, and rollover-induced query failure rates across RFC 6781, RFC 7583, and draft-ietf-dnsop-dnssec-key-timing implementations.
Testbed Topology
- Authoritative Cluster: 3x AMD EPYC 7763, 256GB RAM, Intel X710 10GbE, Linux 6.8 with PREEMPT_RT
- Recursive Validators: 5x Graviton3, 64GB RAM, ENA 25GbE, FreeBSD 14-CURRENT
- Traffic Generator: MoonGen/DPDK 23.11 on dual Xeon Platinum 8480+
Key Metrics
| Metric | Unit | Target |
|---|---|---|
| KSK Rollover Latency (RFC 6781) | ms | < 50 |
| ZSK Rollover Latency (RFC 7583) | ms | < 10 |
| Validator Cache Invalidation Rate | %/hr | < 0.01 |
| Signature Generation Throughput | k sig/s | > 200 |
