SaM: thE nEW Standard in EthErnEt tESting

ITU-T Y.1564 is the new standard for turning up and troubleshooting Carrier Ethernet services. This methodology is completely
adapted to today’s Ethernet services, especially mobile backhaul and commercial services. Up to now, RFC 2544 has been the
most widely used methodology. However, it was designed for network device testing in the lab, not for services testing in the field.
ITU-T Y.1564 is the first testing standard developed for the field. It has a number of advantages over the RFC 2544 including
validation of critical SLA criteria such as packet jitter and QoS measurements. This methodology is also significantly faster, thereby
saving time and resources while optimizing QoS.

Contrary to other methodologies, EtherSAM supports new multiservice offerings. EtherSAM can simulate all types of services
that will run on the network and simultaneously qualify all key SLA parameters for each of these services. Moreover, it validates
the QoS mechanisms provisioned in the network to prioritize the different service types, resulting in more accurate validation
and much faster deployment and troubleshooting. EtherSAM is comprised of two phases, the service configuration test and the
service performance test.

Service Configuration Test

The service configuration test consists of sequentially testing each service to validate that the service is properly provisioned and
that all specific KPIs or SLA parameters are met. A ramp test and a burst test are performed to verify the committed information
rate (CIR), excess information rate (EIR), committed burst size (CBS) and excess burst size (EBS).

Service Performance Test

Once the configuration of each individual
service is validated, the service performance
test simultaneously validates the quality of all the
services over time.
