Accedian Networks Introduces Zero-Latency Traffic Shaping

By Anshu Shrivastava, TMCnet Contributor


Montreal, Canada-based Accedian Networks (News - Alert), a provider of Packet Performance Assurance solutions for telecom, cable and wireless communications providers, has introduced a zero-latency traffic shaping feature for Ethernet demarcation units. 
Accedian Networks explains that this advanced functionality allows service providers to “accelerate real-time services, reduce network overhead and economize bandwidth” for performance-intensive Ethernet & MPLS business services, 3G and 4G wireless backhaul, and inter-carrier handoff and peering applications.
Unlike store-and-forward methods, commonly implemented in network switches and routers, company officials pointed out that “Fast-Thru traffic shaping transmits critical, real-time traffic with no added delay or jitter.”
The availability of real-time traffic selection option allows service providers to define priority flows based on a wide range of Ethernet and IP packet characteristics. This, according to officials, ensures Quality of Service (QoS) sensitive applications meet demanding performance requirements often specified in Service Level Agreements (SLAs).
Traffic shaping is available on Accedian Networks’ recently introduced MetroNID demarcation unit, also capable of bandwidth policing, traffic filtering and Ethernet service creation, all powered by its hardware-based Fast-Thru architecture. 
Officials said that the MetroNID combines these capabilities with an entire suite of service assurance features providing continuous SLA monitoring, layer 1-4 loopbacks, in-service throughput testing and standards-based Operations Administration & Maintenance (OAM) functionality.
“Service providers have long-awaited test & measurement features integrated into their network elements as the combination of service creation and service assurance drives simplified deployment of differentiated services with exceptional QoS,” said Patrick Ostiguy (News - Alert), founding president & CEO at Accedian Networks. 
He also said that with a twist of innovation, his company has addressed this unfulfilled demand by integrating carrier-class service creation functionality into their trusted service assurance solutions. 
Ostiguy noted that already, service providers are deploying these combined capabilities to establish efficient, high-performance business access and 3G/4G wireless backhaul services.
