	abstract = {Systematic monitoring of performance characteristics of mobile broadband networks can help users, operators, and regulators understand this increasingly critical infrastructure. We report the results of a measurement study of round trip delays in two mobile networks in Norway using over 200 geographically distributed subscriptions for a period of one month. In general, we find high variation in delay within the same radio access type and RRC state. Across both networks we study, we observe connections with round trip delays of several seconds, often multiple times per hour, that are more frequent when nodes are moving. Correlating these extreme delay events with available metadata, we find they are related to handovers, radio state transitions, and retransmissions at the link and physical layers.},

	abstract = {In February 2011 the Internet Assigned Numbers Authority (IANA) exhausted its free pool of IPv4 addresses, and the regional registries (RIRs) have started to run out of IPv4 addresses as well. As RIRs have started rationing allocations, IPv4 transfer markets have emerged as a new mechanism to acquire IPv4 addresses. Barring a few high-profile exceptions, IPv4 transfers have largely flown under the radar. In this work, we use the lists of transfers published by three RIRs to characterize the transfer market - the types of players involved, the sizes and characteristics of transferred address blocks, and visible effects on the routing table. Next, we take first steps toward detecting address transfers using BGP data from the Routeviews and RIPE repositories from 2004-2013. We identify reasons why legitimate changes in prefix origin could be confused as transfers, and implement a series of 10 filters that remove 86\% of candidate transfers. We find the remaining number of inferred transfers is increasing over time. We could confirm few (0.16\%) of these transfers using RIR-published transfer lists; while our inference methodology undoubtedly yields false positives, a black market for IPv4 transfers may exist as well.},

	abstract = {We use historical BGP data and recent active measurements to analyze trends in the growth, structure, dynamics and performance of the evolving IPv6 Internet, and compare them to the evolution of IPv4. We find that the IPv6 network is maturing, albeit slowly. While most core Internet transit providers have deployed IPv6, edge networks are lagging. Early IPv6 network deployment was stronger in Europe and the Asia-Pacific region, than in North America. Current IPv6 network deployment still shows the same pattern. The IPv6 topology is characterized by a single dominant player - Hurricane Electric - which appears in a large fraction of IPv6 AS paths, and is more dominant in IPv6 than the most dominant player in IPv4. Routing dynamics in the IPv6 topology are largely similar to those in IPv4, and churn in both networks grows at the same rate as the underlying topologies. Our measurements suggest that performance over IPv6 paths is comparable to that over IPv4 paths if the AS-level paths are the same, but can be much worse than IPv4 if the AS-level paths differ.},
