Service Drivers and Challenges

• Users demanding lower cost, converged and personalized services – Broadband services with high performance, feature richness, dynamic control and reliability • Complexity in networks, services, vendors and markets • Increasing network diversity in: – Industry standards – Carrier models – Product architectures • Need for vendor innovation while preserving interoperability iPOP2009, Tokyo, Japan Page 4

Optical Network Transformation

A Work in Progress

Key drivers

• Capacity • Performance • Reliability SONET/SDH rings DCS WDM pt-to-pt

Past Key drivers

• Service assurance • Bandwidth optimization • Automation NG-SONET/SDH ASON/GMPLS ROADM

Key drivers

• Convergence • Operational efficiency • Availability Transparent photonics

Packet-based Transport Tunable ROADM ASON/ GMPLS OTN Future Today Much attention is on emerging technology, yet carriers must deliver services over diverse networks based on legacy, contemporary and cutting edge technologies.

ASON Architecture and OIF IAs

• ASON architecture addresses the transport network evolution – Heterogeneous network topologies, technologies, and applications – Diverse internal control plane protocols, including management-based – Separation of transport and control planes • OIF complements the work of optical standards bodies – Implementation Agreements (IAs) based on standards – Interoperability testing and prototyping of solutions Management plane

Transport Layer N-2 Call/Connection Flow (e.g. OTN)

Edge nodes typically provide layer adaptation and multi-layer control plane. Core nodes typically operate in single server layer Supports non-disruptive modification (BW or VLAN IDs) to meet varied demands of client while in-service Versatile – supports only layers needed (e.g Eth-VCAT-SDH, packet over WDM) yet supports multiple layer adaptations – Server layer call/connection signaling flow completes before client layer iPOP2009, Tokyo, Japan Page 10
