Broadband Vision

Explore likely changes in broadband technology, from asymmetric to symmetric speeds, higher peak-to-average ratios, and new applications like energy management and medical monitoring. Discover the need for multi-homing, identity services, and security against botnets. Address engineering challenges like user support costs and edge service creation, paving the way for the "future Internet." Learn about NSF FIND & GENI projects at Columbia University.

  1. Broadband Vision Henning Schulzrinne Columbia University

  2. 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

  3. 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

  4. 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
