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. IEEE Globecom ‘ 99 - 99/12/06 - 5
Summary • Collapsing layers, more functionality • Intelligent Optics • Packet / Optics Inter-working • Convergence of Admin Domains IP over (ATM, SONET, WDM)? Packet over Intelligent Optics. IEEE Globecom ‘ 99 - 99/12/06 - 6
