Zayo Bandwidth Deploys Accedian Networks Platform

Accedian Network’s ESAP Ethernet Service Assurance Platform enables premium, SLA-backed QoS for Zayo’s high performance 3G and 4G mobile backhaul offerings.

Montreal, Canada, March 27, 2008 --( Accedian Networks, a leading provider of Packet Performance Assurance solutions for telecom, cable and wireless operators, announced today that Zayo Bandwidth, a regional provider of high bandwidth services, has selected and deployed Accedian Networks’ ESAP Ethernet Service Assurance Platform to monitor Quality of Service (QoS) and assure Service Level Agreements (SLAs) in its high performance Ethernet wireless backhaul network in the Northeastern US.

Zayo Bandwidth’s network spans 95 markets in 12 states by leveraging over 17,000 route miles of fiber. As part of its growing service portfolio, Zayo provides carrier-grade Ethernet wireless backhaul for emerging, packet-based 3G and 4G wireless networks. Accedian Networks EtherNID packet assurance demarcation units and the functionality of the ESAP platform enable Zayo’s Ethernet backhaul services to meet the strict SLAs required by 3G, WiMAX and LTE wireless networks currently in deployment nationwide.

Accedian Networks’ solution provides service assurance for point-to-point, multi-point and mesh network configurations, allowing wireless backhaul providers to guarantee service performance between each base station and the Mobile Switching Center (MSC). Unique in-service test functionality provides continuous monitoring of all critical SLA parameters, including one-way latency, jitter, committed throughput and service availability without affecting critical, real-time applications such as VoIP and mobile video.

“Accedian Networks’ platform helps us to deliver SLA-backed wireless backhaul services by providing Ethernet performance monitoring and management visibility directly to each cell-site.” commented Troy Kau, Vice President of Engineering at Zayo Bandwidth. “The EtherNIDs versatility as a both an in-line measurement probe and intelligent demarcation device allows us to fully instrument our network, establish end-to-end Ethernet OAM, and, in relevant applications, provide fiber extension to cell sites in a cost-effective manner.”

“Our solutions are optimized for the SLA assurance demands of high-performance 3G and 4G wireless backhaul networks.” explained Patrick Ostiguy, founding President & CEO of Accedian Networks. “Our unique, carrier-grade, silicon-based design allows our units to process all packets passing through them at full wire-speed, enabling a wide array of service creation and assurance functionality including service mapping, bandwidth policing, traffic filtering, and in-service RFC-2544 throughput testing – all without affecting the service itself.”

Accedian Networks’ EtherNID demarcation units will be included in a mobile backhaul demonstration at CTIA Wireless 2008, 1-3 April, Las Vegas, NV at the Nortel booth, #1939. EtherNID units running the Packet Assurance Agent (PAA TM) will provide live monitoring of the exceptional one-way delay and jitter performance of Nortel’s latest generation Optical Multiservice Edge (OME) mobile backhaul solutions. Accedian Networks’ products will also be on display at the JDSU booth, #3202.
