Purpose and structure
• To gain an understanding of how optical
technology developments will evolve over next 2,
5 years and how they can benefit R&E networks

Interfaces
•
•
•
•
•
Market drivers for 40+Gbps
what signalling and protocol features
implications of 40+Gbps on fibre infrastructure
standards vs. proprietary solutions
single channel, multichannel, trasnport system
between DWDM
• colours vs. SONET framing
Reach and resilience
• What resilience techniques are available
• (N)RENS rely mostly on multiple unprotected services
• how does 40+Gbps affect reach
BW grooming
• Alternatives to SDH to inject different signals and
present them as separate interfaces to users
• Granularity
• Can they span multiple wavelengths
• Standards
Circuit switching
• OEO vs. OOO
• real operational implications of both
Network management
• Peer vs.overlay model for IP and optical
integration
• interdomain allocation of resources
• SNMP, accounting
Service model
• Tools for managing (N)REN infrastructure
• managed fibre
• tools for interdomain operation
