Broadband Vision Henning Schulzrinne Columbia University
Likely changes • 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
New services • 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
Research issues • 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
