Virtual Ethernet Rings - Extending Ethernet LAN Functionality to Carriers’ existing SDH/SONNET WAN, Metro and Transport Infrastructure



Appian Communications, providers of carrier class optical switching technology, today announced a major enhancement to its Optical Services Activation Platform (OSAP), enabling companies to extend Ethernet LAN functionality across their carrier’s broader WAN, metro and transport infrastructure. Appian’s newly released ‘Virtual Ethernet Ring’ technology allows carriers to offer Virtual Private LAN and Private LAN services which extend the simplicity and multipoint connectivity of a customer’s Ethernet LAN across a carrier’s existing metro, regional or long haul SONET/SDH network. Carriers benefit from the revenue and profit potential of next-generation packet services that are flexible, scalable and carrier quality.



With Virtual Ethernet Rings, multiple customer and partner sites can connect to the Virtual Private LAN or Private LAN service through standard Ethernet connections. The result is what appears to be an extension of the company’s LAN, its own private Ethernet domain that may stretch across continents or as far as the carrier’s network allows. The pioneering work on Virtual Ethernet Ring technology has also helped Appian to win top honours at this year’s SuperComm conference in the US, for access networking technology for public networks.



Michael Howard, principal analyst and co-founder of Infonetics Research, comments, “all Ethernet services are not equal, and Appian continues to show leadership in the breadth of its Ethernet-over-SONET/SDH services capabilities. Premium services like Ethernet Private Line, Ethernet access to existing frame relay/ATM/IP services, and now resilient, multipoint Virtual Ethernet Rings, are key for carriers to profit from the migration to next-generation packet services.”



For carriers, Appian also simplifies the migration to these more profitable next generation Ethernet packet services. OSAP allows carriers to deploy Virtual Ethernet Rings over a standard SONET/SDH/DWDM network in parallel with existing voice TDM services, allowing them to offer new Ethernet services without the need for a complete new infrastructure whilst protecting existing revenues from existing services. Native Ethernet mechanisms, including auto discovery, then enable a simple and scalable multipoint (any-to-any) service. Based on the OSAP’s innovative Ethernet over SONET/SDH architecture, the service can be securely dedicated to an individual customer, or it can be efficiently shared across multiple customers, with the ability to explicitly guarantee bandwidth that scales from 1 Mbps to 1 Gbps in 64 Kbps increments.



About Appian Communications



Appian is removing the final metro area bottleneck to new optical service revenues. Designed to enable growth in carrier revenue and profitability, the Appian solution combines the low cost and simplicity of Ethernet with the resilience and scale of established SDH/SONET networks to enable carrier-class Ethernet services that include secure Ethernet Private Lines, Virtual Private LANs and scalable Internet Access. With its integrated TDM service support, the Optical Services Activation Platform™ (OSAP™) is a best-of-breed solution that simplifies the migration from today’s rigid, circuit-optimised voice and private line offerings to these next-generation service offers. Appian award winning OSAP products are currently shipping to emerging and established providers, including NTT Communications, around the world.
