Cyan Unveils EthernetFLEX to Enable New Carrier Revenue Sources

New Software Defined Metro Networking Capabilities Simplify Usage-Based Ethernet Services

PETALUMA, CA--(Marketwire - Apr 16, 2012) - Giving Ethernet service providers yet another weapon in the competitive battle to deliver differentiated -- and profitable -- services, Cyan today announced EthernetFLEX(SM). A new application embodied in the Cyan 360 software suite and Z-Series™ packet-optical transport platforms (P-OTPs), EthernetFLEX couples robust traffic policing with powerful software-based planning, management, and verification to simplify the delivery of a new wave of Ethernet services. As part of a broader metro transformation toward software defined metro networks, EthernetFLEX-based services are well suited for business Ethernet, wireless backhaul, and wholesale transport, providing service level guarantees with burstable bandwidth allocations that become the basis for usage-based service models.

Service providers and enterprise IT managers around the world are struggling to cope with exponential increases in traffic resulting from of an explosion in mobile devices, cloud computing and storage, and streaming video. The ability to accurately predict and provision the optimal amount of capacity is a constant challenge.

According to John Greene, Chief Network Engineer with Great Plains Communication, "This is exactly the type of capability we have been searching for. It allows us to more accurately meet our customers' bursty bandwidth requirements without an unnecessary increase in the size of their pipe, thereby reducing the pressure to expand our network capacity. This will allow us to defer some capital costs until they are absolutely needed."

For enterprise IT managers, buying network services with substantial excess capacity to support rapidly scaling future requirements means paying for bandwidth that frequently goes unused. However, if they purchase services that are right-sized for current traffic demands, they face the inevitable clipping of service throughput and the time-consuming process of negotiating and signing new contracts for higher capacity services. Service providers have had two choices. One option was to over-provision network capacity -- and not charge customers for excess utilization. The other option was to throttle back throughput to the level which the customer has subscribed -- which ultimately results in a degraded service experience. EthernetFLEX offers a powerful new option to improve service quality and optimize cash flow for both service providers and their customers.

According to Michael Howard, principal analyst and co-founder of Infonetics Research, "EthernetFLEX is another example of how Cyan is leveraging software to access untapped network potential to support useful new services. Ethernet has always had a burstable capability. However, the cost and complexity of providing that capability in a deterministic manner, along with back-office integration for billing, and a customer portal to view actual usage, is too difficult for most to implement. Cyan's integration through EthernetFLEX takes this model from a great concept to a very useful reality."

How EthernetFLEX Works

EthernetFLEX employs committed and excess information rate bandwidth allocations. Cyan Z-Series P-OTPs with high-performance packet service modules track utilization on a per-service basis. Packets in excess of the committed information rate (CIR) are colored yellow but allowed to pass. Yellow packets, which are eligible for discard in the event of congestion, are only counted by the network if they are successfully delivered to their destinations. The CyMS™ network management system gathers and pushes this data to CyPortal™ to track and report usage metrics for the customer's usage reporting and third-party billing applications.

Tom Corker, Cyan vice president of product management and business development, added, "EthernetFLEX benefits service providers as they transform their metro networks in a number of ways. In addition to the obvious attraction of incremental revenue from existing assets, it illustrates how Cyan's evolutionary approach to a software defined metro network will ultimately maximize revenues, while minimizing costs."
