Accedian Networks has updated support for the most recent Ethernet Operations, Administration and Maintenance (OAM) standards, which are implemented in the company’s EtherNID and MetroNID packet assurance demarcation units. 

With OAM, service creation and assurance functionality, the units allow service providers to deploy, monitor and maintain carrier-grade Ethernet services over multi-vendor, multi-technology and multi-carrier networks.

Ethernet service OAM, based on the IEEE 802.1ag and ITU-T Y.1731 standards, provides a set of features for connectivity fault management (CFM) and performance monitoring (PM), Accedian said. The company’s demarcation units now offer all 35 key aspects of service OAM, allowing service providers to deploy OAM at critical management points throughout their networks – including customer and cell sites and aggregation and carrier hand-off points – without upgrading existing infrastructure.

Accedian has coupled its OAM feature set with the demarcation units’ hardware-based packet processing engine, allowing the company to monitor up to 100 services per unit, provide real frame loss in place of estimates, perform high-capacity loopback testing using the standards-based loopback messages, and measure one-way delay and jitter with microsecond resolution.

“Accedian Networks has a history of offering the latest OAM functionality, critical as standards continue to evolve and become central to managing and maintaining carrier-grade Ethernet services,” said Patrick Ostiguy, founding president and CEO of Accedian. “We also cover key gaps in the standards by offering functionality impossible to implement in software, such as seamless in-service throughput testing, automated turn-up testing, and advanced Ethernet and IP performance monitoring that cover all aspects of packet performance assurance.”
