Accedian Networks Announces Support to Ethernet OAM Standards
By Anshu Shrivastava, TMCnet Contributing Editor
Accedian Networks has announced updated support for the most recent Ethernet Operations, Administration and Maintenance (OAM) standards.
The OAM standards have been implemented in the company’s EtherNID & MetroNID packet assurance demarcation units. Based on the IEEE (News - Alert) 802.1ag and ITU-T Y.1731 standards, the Ethernet service OAM provides a comprehensive set of features for connectivity fault management (CFM) and performance monitoring (PM).
With the deployment of OAM, service creation and assurance functionalities, EtherNID (News - Alert) and MetroNID now allows service providers to implement, monitor and maintain carrier-grade Ethernet services over multi-vendor, multi-technology and multi-carrier networks.
The company’s demarcation units currently offer all 35 aspects of service OAM. Company officials said that this allows service providers to transparently deploy OAM at management points throughout their networks.
These management points include customer and cell sites, aggregation and carrier hand-off points - without upgrading existing infrastructure. Moreover, OAM standards comply with the latest versions of service, which enables interoperability with OAM-enabled switches and routers.
Unlike the competing network elements’ software-based implementations, Accedian Networks has coupled its OAM feature set with the demarcation units’ hardware-based packet processing engine.
Officials said that this approach brings a “level of performance” to OAM measurements, including the ability to monitor up to 100 services per unit, provide real frame loss in place of estimates.
In addition, other abilities include loopback testing using the standards-based loopback messages, and measure one-way delay and jitter with microsecond resolution—essential to maintaining the performance specified in demanding service level agreements (SLAs).
Accedian Networks is a provider of Packet Performance Assurance solutions for telecom, cable and wireless communications providers. The company delivers carrier-grade, packet-based applications including voice over Internet Protocol (VoIP), Internet protocol television (IPTV (News - Alert)), videoconferencing and transparent LAN services over Ethernet, IP/MPLS, and wireless 3G /4G /WiMAX networks.
“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 (News - Alert), founding president and CEO at Accedian Networks.
He added that the company also covers 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.
