EtherSAM Bidirectional Results
EXFO’s EtherSAM approach proves even more powerful as it executes the complete ITU-T Y.1564 test with bidirectional
measurements. Key SLA parameters are measured independently in each test direction, thus providing 100 % first-time-right service
activation—that is the highest level of confidence in service testing.
rfc 2544 tESting
In cases where the Ethernet service is delivered via switched transport, the RFC 2544 measurements provide a baseline for service
providers to define SLAs with their customers. They enable service providers to validate the quality of service (QoS) delivered and
can provide them with a tool to create value-added services that can be measured and demonstrated to customers. For example,
these tests provide performance statistics and commissioning verification for virtual LANs (VLANs), virtual private networks (VPNs)
and transparent LAN services (TLS), all of which use Ethernet as an access technology.
The FTB-8120NGE/8130NGE Power Blazer modules come with a complete set of RFC 2544 test capabilities, including:
›
Throughput testing
›
Burst (back-to-back) testing
›
Frame loss analysis
›
Latency measurement
BEr tESting
Since the transparent transport of Ethernet services over physical media is becoming more widespread, Ethernet is increasingly
carried across a variety of layer 1 media over longer distances. This creates a growing need for the certification of Ethernet transport
on a bit-per-bit basis, which can be done using bit-error-rate testing (BERT).
BERT uses a pseudo-random binary sequence (PRBS) encapsulated into an Ethernet frame, making it possible to go from a
frame-based error measurement to a bit-error-rate measurement. This provides the bit-per-bit error count accuracy required for
the acceptance testing of physical-medium transport systems.
In addition to BER testing, the FTB-8120NGE/8130NGE Power Blazer modules also provide service disruption time (SDT)
measurements.
