Broadband Vision

This overview discusses potential changes in broadband infrastructure and services, as outlined by Henning Schulzrinne from Columbia University. Key trends include the transition from asymmetric to symmetric upload/download ratios, increased IPv6 adoption, and the growing need for reliable connectivity in diverse environments. Emphasis is placed on new applications that enhance energy management, medical monitoring, and home safety. The report also highlights the importance of edge hosting, identity services for emergency responsiveness, and the push towards robust security measures to combat threats like botnets.

  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
