Transforming Transport Networks
To stay profitable, service providers must focus on new revenue-generating services while carefully controlling their cost structures. At the same time, new bandwidth- hungry services, such as triple play and Ethernet virtual private networks (VPNs), are redefiining the underlying transport-infrastructure requirements. These changes are driving the move from circuit-based transport, using Time Division Multiplexing (TDM), to packet-based transport, using Ethernet in MANs and WANs.
Driven by end-user demand for new services, service-provider network capacity is growing rapidly, with these networks transporting a wide variety of traffic. Service providers all need to assess how their existing metro and core networks will accommodate trends and transitions in traffic patterns.
The new-services introduction is probably the most critical factor to a service provider’s success. The increasing demand for bandwidth to deliver new services is not reflected in comparable increases in revenue, presenting a significant business challenge. The Alcatel-Lucent 1850 TSS-320 helps service providers maximize their profiitability by transporting any service mix while keeping tight control of costs.
