The Changing Service Landscape

Ethernet Business Services

Enterprise customers are conducting an increasing amount of their business elec- tronically, using information and com- munications technology (ICT) to drive sales, improve customer relationships, train staff and simplify procurement. This is being done over metro, national and international boundaries. Enterprises want convenience, simplicity and flexible bandwidth across the wide area network, but with the quality of service and control that is critical for business networking applications like video, voice and data. Enterprises are turning to their service providers for help with their communications challenges.

Fortunately, the Alcatel-Lucent solution enables service providers to respond to these needs with Ethernet-based business services, such as virtual private LAN services (VPLS) and virtual leased line (VLL). These services enable enterprise customers to increase business services and reduce costs, thanks to the opera- tional cost benefits of Ethernet and the predictable quality of service (QoS) characteristics of multiprotocol label switching (MPLS).

“There is clear demand from our customers for reliable Ethernet services. The Alcatel VPLS solution will take us from a basic Internet offering to a new level by enabling us to deliver differentiated Ethernet VPN services.”
