 Asymmetric (download)  symmetric more uploads (backups, video, other UGC) IPv6 with lots of customer-controlled addresses  Higher peak-to-average ratio? want quick uploads broadband – more than 10 Mb/s download  New applications substitution for dedicated services (video) energy management, home safety, medical monitoring  No substantial distinction between residential and small business LANs, lots of diverse devices, limited technical training  Some need high reliability even with power outages

 Multi-homing business models that allow fail-over to secondary wired or wireless network  Content and service hosting close to edge allows low-cost (shared) access to content non-discriminatory  Identity services certified geo/civic location (  needed for NG911) subscriber certificate (  user auth, also for NG911)  Security services e.g., botnet prevention

 Engineering oriented: reduce user frustration and support costs multi-homing and other reliability issues sensible usage-dependent charging edge content and service creation botnet detection and isolation  Longer term:  “future Internet”  NSF FIND & GENI
