Accedian Networks has added a performance assurance agent (PAA)\u00a0into its EtherNID Ethernet Demarcation Device product line. The Accedian EtherNID allows constant in-service monitoring of service-level agreement (SLA) parameters including packet loss, latency (delay), jitter (delay variation) and continuous end-to-end path continuity check (availability). Using a silicon-based architecture,\u00a0the EtherNID features the market\u2019s lowest intrinsic latency and jitter, thus allowing it to yield the highest-precision measurements with an outstanding one-microsecond resolution and provide a true view of the end customer experience, the company says. Accedian Networks\u2019 PAA operates in a point-to-point or point-to-multipoint fashion and is capable of monitoring multiple simultaneous flows. It operates at both Layer 2 and Layer 3 (IP) and, Accedian Networks claims, can assure SLAs on a per-VLAN, per-CoS, per-ToS and per-EVC basis.\u2014Esther SchindlerCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
