Alcatel-Lucent 7450 Ethernet Service Switch
Enabling Profitable Carrier Ethernet Services
The Alcatel-Lucent 7450 Ethernet Service Switch (ESS) sets a new market standard for enabling the delivery of
profitable Ethernet business services in metro, national and international network environments. It also
provides high density service-aware Ethernet aggregation for consumer triple-play services over IP/MPLS-based
networks. The Alcatel-Lucent 7450 ESS is purpose-built for the service provider market, with an architecture
service providers to offer new, revenue-generating services for both the consumer and business markets.

The Changing Service Landscape
Ethernet Business Services
Enterprise customers are conducting an increasing amount of their business elec­tronically, using information and com­munications 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.
Figure 1. The Value of MPLS-Enabled Ethernet
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 opera­tional 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.”

(VPNs) complete the service provider service mix — ensuring that they can confidently mix and match Layer 2 and Layer 3 VPN services based on what their customers want. VPLS expands the next-generation VPN service market and enables service providers to offer their customers a Layer 2 multipoint service that provides higher bandwidth than frame relay, with the same QoS as frame relay or ATM. Also, unlike IP­VPNs, which require the enterprise to share routing information, VPLS allows the enterprise to retain routing control and provides the flexibility to support multiple protocols, in addition to IP, that are present in many enterprise networks.
With a next-generation VPLS imple­mentation, service providers can tailor service definitions that directly align with the customers’ business objectives and thereby create value. The Alcatel­Lucent 7450 ESS delivers VPLS today with the ability to have different applications run within a single VPLS service with distinct service level agree­ments (SLAs), as well as an aggregate SLA for each customer. This greater degree of control for service level differentiation is delivered through an extensive QoS implementation, including hierarchical QoS (H-QoS) as illustrated in Figure 2.
