LONDON -- Ebone, Europe's original, most experienced broadband and IP optical networking company, is using equipment from CoSine Communications, Inc. (Nasdaq: COSN), the leading provider of IP Service Delivery Platforms, to enhance the delivery of value-added IP services across Europe's largest optical Internet backbone. Ebone's deployment of CoSine's IP Service Delivery Platform enables them to add to their portfolio of advanced IP services such as IPSec VPNs and Gauntlet Application Proxy Firewalls to subscribers that will dramatically reduce the cost of enterprise networking, communications and Internet security activities. Ebone is already providing Real Media, the world's second-largest on-line advertising company, with its new IP intranet solution, powered by the CoSine IPSX 9000 service processing switch. By upgrading to an IP-based virtual private network (IP VPN) through the Ebone solution, Real Media now has a secure and flexible platform upon which to increase the efficiencies of its international operations. Ebone's IP VPN technology eliminates the prohibitive costs of a traditional Frame Relay or ATM private network while providing scalability for the future.EboneCoSine Communications Inc.
