Y.1564 - Ethernet Service Activation Test Methodology
Overview
This document describes ITU-T Y.1564, a standard for Ethernet Service Activation Testing (SAT). It focuses on validating Service Level Agreements (SLAs) through Key Performance Indicators (KPIs) such as Frame Delay (FD), Frame Loss Ratio (FLR), and Frame Delay Variation (FDV) in a single test. The document also covers traffic classification, service prioritization using Quality of Service (QoS), and performance verification mechanisms like Loopback Messages (LBM).
The SAT feature allows service providers to verify Ethernet service configurations and performance before activating them for customers.
OcNOS switches execute SAT by generating test traffic, collecting performance data, and ensuring SLA compliance before activation. This supports validation for both upstream (traffic entering the network interface) and downstream (traffic exiting the network interface) directions, with results displayed post-test.
The SAT allows service providers to verify Ethernet service configurations and performance before activating them for customers.
Currently, this feature is supported on OcNOS devices equipped with the Qumran2 and Jericho2 chipsets.
Feature Characteristics
An SLA (Service Level Agreement) is a binding agreement between a service provider and a customer, ensuring that the delivered service meets agreed-upon performance levels.
To meet SLA obligations, ITU-T Y.1564 provides a standardized procedure for verifying SLAs by:
Validating service configuration: Ensuring each Ethernet service is correctly set up.
Validating service quality: Ensuring the delivered quality meets user expectations.
Each User Network Interface (UNI) runs multiple services qualified by KPIs. The SAT verifies the network's ability to handle traffic within design parameters, ensuring compliance with Bandwidth Rate Profiles and Performance Criteria.
Bandwidth Profile
The SAT generates traffic based on the configured bandwidth profiles:
• Committed Information Rate (CIR): The guaranteed bandwidth available at all times for a specific service.
• Excess Information Rate (EIR): Additional bandwidth above the CIR, available based on network load.
OcNOS applies bandwidth profiles that include KPIs to indicate minimum performance requirements. Both CIR and EIR are essential for maintaining SLA compliance.
Performance Criteria
The SAT collects the following KPIs to ensure SLA requirements are met:
• Frame Delay (FD): Measures latency, the time taken for a packet to travel from source to destination.
• Frame Delay Variation (FDV): Also known as jitter, it measures variability in packet arrival times.
• Frame Loss Ratio (FLR): The percentage of packets lost due to errors or network congestion.
Color Codes for Traffic Policing
OcNOS uses traffic color codes to police ingress packets and manage their priority:
• Green: Traffic guaranteed at all times for a specific service.
• Yellow: Best effort traffic, utilizing excess bandwidth when available.
• Red: Traffic dropped without disrupting guaranteed services.
Quality of Service (QoS)
QoS ensures efficient traffic prioritization in the network. By assigning priority levels to each service and using appropriate prioritization algorithms, OcNOS delivers higher service quality for critical traffic. QoS differentiates traffic using specific fields in frames, ensuring higher-priority traffic receives preferential treatment.
Service Traffic Test Types
OcNOS performs the SAT on interfaces provisioned with rate profiles. Performance statistics are collected during the test (either locally at PE1 by looping the traffic back from PE2, if the test is two-way or at PE2, if the test is one-way.), which operates in either:
Upstream: Traffic is generated at the UNI and forwarded towards the network (From PE1 UNI to PE2 UNI).
Downstream: Traffic exit at the interface (PE1 network interface to PE2 network interface).
The illustration below depicts the traffic flow of Upstream and Downstream.
Upstream and Downstream Traffic Flow
SAT Performance Statistics
During SAT testing, the following statistics are collected to verify SLA compliance:
• Frame counts
• Errors
• Out-of-order frames
• Lost frames
• Minimum/maximum frame delay
• Frame delay variation
In two-way tests, Loopback Messages (LBM) and Loopback Replies (LBR) are used to measure throughput and frame loss. LBMs are sent as test traffic, while the peer device responds with LBR packets, allowing OcNOS to collect performance data.
SAT Profile Configuration
To perform SAT testing, a rate profile must be configured. It includes parameters such as CIR, EIR, Class of Service (CoS), and Drop Eligibility Indicator (DEI). Multiple test streams can be configured and run sequentially or in parallel.
For delay measurement, Delay Measurement Messages (DMMs) are used:
• When EIR is configured, VLAN priorities alternate between CIR CoS and EIR CoS.
• If EIR is not configured, only CIR CoS is used.
SAT profiles allow for the following operations:
• Create, abort, delete, or start a test
• Clear test history and results
• Configure frame size profiles for non-default frame sizes
• Accept or reject frame loss and delay criteria for CIR traffic
• Delete SAT rate profile or acceptance profile
• Create SAT rate profile or acceptance profile
• Delete SAT frame size profile
• Display SAT test summary and detailed SAT test results
Limitations:
• Supported only on Qumran2 and Jericho2C+ chipsets.
• Limited to 2-way traffic testing.
• CRC validation is not supported for SAT frames due to hardware limitations.
• LBM/LBR supports only a single TLV length, which may cause malformed frames for multiple frame sizes.
• LAG load balancing is supported only for UP MEPs; DOWN MEPs are unsupported.
• Supports a maximum of 8 CIR-EIR stream pairs, allowing up to 32 streams in various configurations. For example, you can configure 8 CIR-EIR pairs alongside 16 CIR-only streams, or alternatively, up to 32 CIR-only streams. This flexibility enables a variety of traffic configurations to accommodate different traffic scenarios.
Benefits
The ITU-T Y.1564-based SAT feature ensures Ethernet services meet SLA requirements before deployment. By validating configuration and performance, it minimizes service disruptions and reduces troubleshooting efforts. The ability to measure KPIs like latency, jitter, and frame loss enables precise SLA verification, resulting in:
• Higher customer satisfaction
• Improved network reliability
• Cost-effective service activation testing
Prerequisites
To implement ITU-T Y.1564 Service Activation Testing (SAT), the following prerequisites must be met:
• Device Support - Network devices (e.g., routers, switches) must support ITU-T Y.1564 standards and the necessary traffic generation and measurement features.
• Configured Network Path - A properly configured network path for test traffic between the source and destination endpoints is required.
• Acceptance Criteria - Clearly defined acceptance criteria for SLAs and performance KPIs (e.g., Frame Delay, Frame Loss Ratio, Frame Delay Variation) to validate test results.
Configuration
Following are the steps required to configure SAT:
1. Configuring rate profiles (CIR, EIR, QoS) that defines the minimum performance standards to ensure.
2. Configuring acceptance profiles (CIR, FLR, FD, FDV). The service must operate at or above the performance levels defined in the acceptance profile to be considered for bringing into service.
3. Configuring frame size profile.
4. Configure a SAT test.
5. Setting up measurement tools, such as Loopback Message (LBM), Loopback Reply (LBR), and Delay Measurement Message (DMM). The packets are generated and responded by OcNOS devices.
6. Executing SAT test by generating traffic in upstream/downstream directions.
7. Collecting and analyzing KPIs.
Topology
The topology uses a EVPN MPLS ELINE services between PE1 and PE2 nodes. It consists of two CE1 and CE2 nodes. Traffic that complies with rate profile is generated on PE1 and sent out through the interface where the service is provisioned.
SAT Topology for EVPN MPLS ELINE Service
Procedure to configure SAT
The procedure given below performs SAT for EVPN MPLS ELINE service. It assumes that the EVPN MPLS ELINE service exist between PE1 and PE2. Ensure the CFM up mep session exists between PE1 and PE2 nodes along with delay-measurement reply on the PE2. Refer to Chapter 5, Y.1731 and CFM Over EVPN ELINE Single Home.
