Evolution of Administrative Domains
“Administrative Domain”
Analogous to “autonomous system”, but incorporates all
aspects of network administration and operation.
• Trend to Convergence of multi-layer admin domains
• Advantages: network efficiency, cost, operations, etc...
Value can be extracted by the
merging of administrative domains.

Summary
• Collapsing layers, more functionality
• Intelligent Optics
• Packet / Optics Inter-working
• Convergence of Admin Domains
IP over (ATM, SONET, WDM)?

Solution Attributes
• Peta-Bits of capacity
Future networks
will need to
have these
attributes.
• Edge-driven
— automated engineering
— near buffer-less core
• Exploits optical technology
— fiber optics
— DWDM
• Cost Effective
— bypass expensive bandwidth
The Internet will require novel approaches that fully
leverage emerging technology.
