Verizon's Network: Past, Present and Future

In a presentation at last week's Lehman Brothers Network Conference, Paul Lacoutre, president of Verizon's Network Services, outlined the planned evolution of Verizon's network to a next generation architecture. Key elements of the company's optical transport network will continue to include SONET and DWDM, deployed in both ring and mesh topologies. An optical control plane will be an enabler for SONET OCx services, dedicated/shared ring services, and optical ESCON/FICON/FC/Ethernet services. The switching layer of Verizon's next generation network will use an IP core based on MPLS to support traditional fast packet services (Frame Relay and ATM) as well as new offerings, such as switched Ethernet transparent LANs, IP VPNs and IP voice. Verizon's access network will encompass mass-market DSL; dedicated and shared fiber buildouts to enterprise customers; and new fiber builds to selected end customers. Enhanced DSL offerings will include static IP service, symmetrical DSL, wireless DSL, MSN8+DSL, and speed upgrades to 1.5 Mbps. Verizon is considering fiber to the premises (FTTP) to both new housing construction as well as for neighborhood overlay builds.
