Performance Monitoring and Reporting

Y.1731 Performance Monitoring

Ethernet services can deliver multiple applications (voice, video and data) and Classes of Service that ensure bandwidth for these applications. These services can be delivered as “best effort”, or Service Providers can provide Service Level Agreements for different types of traffic. 4G/LTE mobile backhaul requires strict SLA guarantees, and Enterprises are requiring more granular SLA metrics for VoIP, private cloud services and financial transaction services.

iConverter® Network Interface Devices (NIDs) provide comprehensive support of the ITU-T Y.1731 Performance Monitoring standard. Y.1731 provides measurement of Frame Loss, Delay, Delay Variation and Availability. iConverter GM4 NIDs feature performance monitoring and testing with nanosecond resolution for the highest levels of measurement accuracy.

iConverter GM4 NIDs support MEF 23.1 Class of Service Performance Objectives that define specific performance metrics for over 20 application types, including Mobile Backhaul, VoIP, Video Conferencing, Financial Services and Cloud Services.

FeaturesBenefits
ITU-T Y.1731 Performance Monitoring Enables delivery of SLAs for value-added revenue and service differentiation
ITU-T Y.1731 threshold monitoring and threshold crossing alerts Ethernet data can deteriorate over time, so threshold monitoring allows for alerts to be generated to provide advanced warning on potential service outages
MEF 23.1 Class of Service Performance Objectives (CPO) Support for MEF 23.1 enables SLAs with application-oriented performance metrics for over 20 application types, including Mobile Backhaul, VoIP, Video Conferencing, Financial Services and Cloud Services
Hardware-based Delay and Delay Variation measurement with nanosecond resolution Highest available performance monitoring for sensitive applications financial transactions and mobile backhaul sync

 

Performance-Monitoring

ITU-T Y.1731 Performance Monitoring OAM probes inject test and monitoring frames in-band with the Ethernet service to measure a variety of service parameters. Probes and standards-based reporting mechanisms provide for periodic and historical measurements.

iConverter NIDs can capture and collect the data from performance monitoring and present it periodically to the service provider’s network management system. This data can be processed and presented in numerical or graphical form to the wholesale operator partner for SLA enforcement, or the Subscriber for proof of SLA conformance.

iConverter NIDs conform to MEF 23.1 Class of Service Performance Objectives. MEF 23.1 is part of Carrier Ethernet 2.0 that define specific performance metrics for over 20 application types, including Mobile Backhaul, VoIP, Video Conferencing, Financial Services and Cloud Services. MEF 23.1 is part of Carrier Ethernet 2.0, and expands on ITU Y.1731 performance metrics to include:

  • Mean Frame Delay
  • Frame Delay Range
  • Inter-Frame Delay Variation
