Meeting the Cap-and-Grow Challenge with MPLS (pdf)
This paper explains how service providers can benefit from investing in Multi-Protocol Label Switching (MPLS) technology in place of tactical legacy equipment upgrades. MPLS wraps a revenue-generating multiservice network edge around a cost-efficient Layer 2 core to reduce expenses and consolidate operations in carrier networks. It combines the connection-oriented control of Layer 2 virtual circuits (VCs) with the efficiency of variable-length packet switching to deliver the flexibility, scalability, efficiency, resiliency and economics that service providers desire.

Evolving Enterprise WANs with Ethernet Service Interworking (pdf)
The continued appeal of Frame Relay (FR) and ATM coupled with the growing attractiveness of Ethernet as a network service has resulted in end user demand for heterogeneous WANs that support a mix of these technologies. Network service providers can capitalize on this demand by supporting service interworking across FR, ATM and Ethernet. Ciena’s DN 7000 Series is an extremely cost-effective, feature-rich, and reliable solution to address carrier-grade service interworking requirements. This paper substantiates the business case for service interworking functionality, explains switching equipment requirements for service interworking and provides a "Service Interworking Technical Primer."

Investment at the Multiservice Edge - Priorities, Trends and Challenges (presented by The Yankee Group)
Carriers have recently begun evolving their networks to better support growth of Layer 2 services via IP/MPLS solution. In particular, recent research by the Yankee Group suggests that aggressive service providers will migrate up to 50 percent of their Layer 2 customers to an IP/MPLS core in the next three years. From a market analysis perspective, this session discusses the investment required to facilitate the migration of Layer 2 services to a common IP/MPLS core, specifically as it relates to multiservice edge switching and routing.

Cost-effective Aggregation for Broadband and Wireless Services
Wireline broadband services using both DSL and FTTP technologies are growing rapidly. Wireless data services in the area of 2G/3G/UMTS infrastructures are another worldwide trend. These two areas share a common need in the area of requiring cost-effective access and aggregation networks. This session will present prevalent network architectures in these scenarios and the technologies involved in each.
