Network Evolution Trends
• Optical Infrastructure– Capacity imperative
• Packet Based Transport & Switching– Multi-service flexibility
• Location of Intelligence (Core vs Edge)– QoS and Bandwidth Granularity/Control
• Convergence of Control & Management Aspects– E.g., Dynamic routing vs protection switching
• Interworking with Legacy Systems

• Application of IP technology into Telecom infra and• specify Interworking between IP and Telecom service/network
IP IssuesPacket based infrastructure
• New architecture for full Packet based infrastructure (inc.Voice)• Migration path from Circuit based to Packet based infra (inc. Interworking)• Service and network capabilities for providing Packet based services• New access technology, OAM and Performance study based on full Packet infra
