Understanding the Impact of Network Infrastructure Changes using Large-Scale Measurement Platforms

  • A number of large-scale network measurement platforms have emerged in the last few years. These platforms have deployed thousands of measurement probes at strategic locations within access and backbone networks and at residential gateways. The primary goal of these efforts is typically to measure the performance of broadband access networks and to help regulators sketch better policy decisions. In this dissertation we expand the goal further by using large-scale measurement platforms to understand the impact of network infrastructure changes. We utilise probes deployed at the edge of the network to measure IPv6 and access network performance. This dissertation largely provides three main contributions: a) Survey on Internet Performance Measurement Platforms: For each performance measurement platform, we present its coverage, scale, lifetime, deployed metrics and measurement tools, architecture and overall research impact. Furthermore, we discuss standardization efforts that are currently being pursued in this space. b) Measuring IPv6 Performance: We present metrics, measurement tools, measurement insights and experience from studying geographically varied IPv6 networks. We provide a comparison of how content delivery over IPv6 compares to that of IPv4. We identify glitches in this content delivery that can help improve user experience over IPv6. Our observations also identify areas of improvements in the standards work within the IETF. c) Measuring Access Network Performance: We perform a characterization of last-mile latency by time of day, by subscriber location, by broadband product subscription and by access technology used by the DSL modem. We show that DSL deployments not only tend to enable interleaving on the last-mile, but also employ multiple depth levels that change over time. Our characterization of last-mile latency can be used by simulation studies to model DSL, cable and fibre access links in the future.
