I’d be interested in seeing a updated/modernized DC internet edge design session, including some of the following topics:

• Carrier path selection and failover (AS-path based, performance/quality based, etc.)
• Path visibility (Tools like ThousandEyes, et al.)
• Public IP mobility and failover between DC’s (BGP strategy, iBGP topology and transport)
• Designing and building backbone connectivity between INET edges @ both DC’s (shared vs dedicated transport, routed vs. stretched segments, etc.)
• DDoS mitigation (BGP, DNS-based techniques, etc.)
• Impacts of IPv6 on all above topics (Design, hardware resources, platform selection, etc.)
