Auditable evidence
A signed report with date, time, measurement equipment and results. Tomorrow, in an ISO audit, a claim or an operator switch, the proof is in your hand.
Home›Y.1564 Certification
ITU-T Y.1564 certification with every installation
Quality demonstrated, not promised
Quality demonstrated, not promised. Every Olivet Telecom connection ships with a signed ITU-T Y.1564 certification report, 5 auditable KPIs and simultaneous multi-stream testing. It's not a speed test — it's the international standard for validating Ethernet services in production with contractual PASS/FAIL thresholds.
Why it matters
Three reasons to demand certification
Why "the speedtest shows fine" is not enough.
Enforceable SLA
The 5 Y.1564 KPIs match the ones in your contract. You have measured, verifiable figures for each penalty criterion.
A baseline to compare with
If an app feels slow tomorrow, you have an initial reference. The NOC can repeat the test and detect real degradation versus the day of installation.

How it works
One methodology, two clear phases
What we actually do on your line before handing over the service.
A · The standard
ITU-T Y.1564 — built for production networks
Y.1564 is an ITU-T recommendation published in 2011 that replaces RFC 2544 for commercial Ethernet services. The IETF itself confirms this in RFC 6815: RFC 2544 was meant for lab use and should not be applied to production networks. Y.1564 was born precisely to fill that gap.
- International recommendation adopted by operators worldwide
- PASS/FAIL thresholds tied to the contractual SLA
- Deterministic durations that can be replicated
- Simultaneous multi-stream: reflects real usage
B · The 5 KPIs
What is measured and why each one matters
Quality isn't just "plenty of Mbps". It's a combination of five parameters that, together, define the real user experience. Y.1564 validates them simultaneously, not separately, because the combined behaviour is where degradation actually shows up.
- CIR 1 Gbps symmetric · bandwidth contractually guaranteed
- EIR additional burst without degrading the CIR
- FTD < 5 ms · one-way latency, critical for video calls and VoIP
- FDV < 1 ms · jitter, critical for audio and video streaming
- FLR < 10⁻⁶ · loss, critical for TCP and sensitive SaaS
C · Two phases
Service Configuration Test + Service Performance Test
A Y.1564 test is split in two phases with different goals. The first verifies that the service can reach the CIR without losing packets via a progressive ramp-up. The second sustains traffic for an extended period to validate the stability of all 5 KPIs under continuous load.
- Phase 1 (Configuration): ramp-up to 110% of CIR · a few minutes
- Phase 2 (Performance): sustained traffic for 15 min to 24 h
- Final report with PASS/FAIL per KPI
- Digital signature from the measurement device for auditability
D · Simultaneous multi-stream
Because testing a single stream misses the point
The key difference with RFC 2544 is simultaneous multi-stream. Y.1564 generates several traffic classes at once (voice, video, data) and measures the KPIs for each one. This mirrors real office usage and catches SLA violations that a single-stream test would never see.
- More than one service measured simultaneously
- Variable packet sizes (64B to 1518B)
- Differentiated classes with Ethernet priority close to ORO
- Realistic validation of the network under production load

Frequently asked
Technical questions
What systems teams usually ask us about Y.1564.
What exactly is ITU-T Y.1564?
An ITU-T recommendation for validating Ethernet services in production. It defines a two-phase methodology that simultaneously measures bandwidth, latency, jitter and loss against PASS/FAIL thresholds.
Why is RFC 2544 unsuitable for production networks?
It was meant for lab use. The IETF itself warns in RFC 6815: 2544 uses a single stream, non-deterministic durations, and has no PASS/FAIL thresholds. Y.1564 was created to fill that gap.
Which five KPIs does it measure?
CIR, EIR, FTD (latency), FDV (jitter) and FLR (loss). Every metric has a contractual threshold and a PASS/FAIL outcome.
How long does the test take and is it intrusive?
Configuration takes a few minutes; Performance runs 15 minutes (default) or up to 24 hours on request. It is carried out during installation and does not affect customer production.
Does the certificate serve as legal evidence?
Yes. The report is auditable, signed and traceable to the measurement equipment. Accepted by ISO audits, quality certifications and SLA claims.
Can the test be repeated later?
Yes. The Olivet NOC can schedule a new Y.1564 test on request, in the same format for easy comparison.
