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).

The Changing Service Landscape
“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.”
