Full Title: "An Internet for Bulk Content Delivery, not Communication: or solving the effects produced by ISP's traffic shaping policies"

Presented by Pablo Rodriguez.


The Internet is witnessing explosive growth in traffic, in large part due to bulk content transfers. Treating such delay tolerant traffic as interactive communications is expensive for ISPs because they dimension their networks based on peak levels of utilization, e.g., the 95th percentile. To limit such costs, many ISPs today are considering traffic shapers at the edge of their networks that rate-limit the bandwidth consumed by bulk ows. Unfortunately, due to the offsets in the local peak hours of utilization at different network links, bulk transfers traveling sufficiently far will be throttled by various ISP between the source and destination resulting in very poor end-to-end rates. To reduce the impact of such problems I will introduce a novel Internet architecture for bulk transfers that significantly reduces operational costs and increases end-to-end transmission rates.
