New multi-stream quality of service (QoS) test capabilities allow service providers to perform fast and simultaneous per-stream measurements to fully qualify SLA parameters through a single test.

Exfo Electro-Optical Engineering has pulled together a wide set of test capabilities to create an integrated test suite for QoS assessment and SLA validation of Ethernet mobile backhaul and triple-play services.

Exfo has combined in its Packet Blazer and Transport Blazer test modules a set of functions that allow service providers to simultaneously test up to 10 different service applications with different QoS levels, based on Ethernet and IP parameters such as VLAN ID (802.1Q), VLAN priority (802.1p), VLAN stacking (802.1ad Q-in-Q), ToS and differentiated services code points (DSCP), the company said.

Specific service profiles including VoIP, video and data can be applied for test configurations. All critical test parameters – throughput, latency, frame loss and packet jitter (RFC 3393) – are accessible simultaneously for each stream, allowing fast and in-depth qualification of all SLA criteria, Exfo said.

“With the growing need to support quality-intensive Ethernet services, whether for commercial or mobile backhaul service offerings, service providers are feeling the intense pressure to efficiently deliver these services to their customers,” said Etienne Gagnon, Exfo’s vice president of product management and marketing.

“With the integration of these key QoS analysis functionalities across our transport and datacom portfolio, service providers will be able to deploy Ethernet services in a more timely and cost-efficient manner.”
