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 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.
Ethernet virtual private networks (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.
Triple Play Residential Services A burgeoning new market exists for Ethernet in the aggregation of consumer triple -play services (see Figure 3). The aggregation network needs to be optimized to meet the demands of voice, video and highspeed Internet services, and above all it must be extremely scalable to support the kinds of subscriber numbers inherent in a consumeroriented service.
The Service Provider Challenge These two distinct markets — Ethernet business services and triple play residential services — generate a challenging list of requirements for service providers: • High scalability in terms of number of subscribers and services • High reliability — only carrier-class (99.
Addressing Growing Markets with an Ethernet Service Switch In contrast to traditional Ethernet switches, the Alcatel-Lucent 7450 ESS was specifically designed for the delivery of business and triple -play services, with MPLS as an integral component of its service-oriented architecture. This next-generation design enables service providers to roll out more services, more quickly — services that are backed by carrier-class reliability and scalability (see Figure 4).
Highly Reliable Carrier Ethernet Services The Alcatel-Lucent 7450 ESS is the industry’s first Ethernet service switch with carrier high availability. More than ever, high availability is at the forefront of the service provider’s criteria for consumer and business Ethernet services.
Carrier-Class Features Provide Carrier-Class Benefits The 7450 ESS represents a generational leap in carrier high availability enabling service providers to improve their network reliability with non-stop Ethernet services and ensure customer SLAs are preserved (see Figure 5). With its advanced feature set, the Alcatel-Lucent 7450 ESS provides a unique set of benefits for service providers, as described in Table 1. Table 1.
Services You Can Bank On As we’ve seen, the Alcatel-Lucent 7450 ESS provides the kind of technological advances required to operate in a service provider environment. Table 2 describes how the Alcatel-Lucent 7450 ESS enables Ethernet services that address the service provider’s inter-region and nationwide requirements. The Alcatel-Lucent 7450 ESS can also be a key component in a network design that calls for service interworking between frame relay/ATM and Ethernet.

These tools allow the service provider to isolate faults and provision services quickly, with an end-to-end perspective, rather than time-consuming connectionby-connection, element-by-element fault tracing and provisioning, which are prone to error. Ethernet also has the potential to provide huge savings in OPEX, compared to legacy services. Ethernet services can be upgraded remotely from the network operations center, without a truck roll.
