Is it possible to extend IPv6?

The IPv6 Hop-by-Hop Options and Destination Options Extension Headers have historically faced challenges in deployment due to a lack of router support coupled with concerns around potential for denial-of-service attacks. However, there has been a renewed interest within the standards community both in simplifying their processing, and in using these extension headers for new applications. Through a wide-scale measurement campaign, we show that many autonomous systems in both access networks and the core of the Internet do permit the traversal of packets that include options, and that the path traversal currently depends on the type of network, size of the option and the transport protocol used, but does not usually depend on the type of included option. This is an encouraging result when considering the extensibility of IPv6. We show that packets that include an extension header can also impact the function of load balancing network devices, and present evidence of equipment mis-configuration, noting that a different path to the same destination can result in a different traversal result. Finally, we outline the current deployment challenges and provide recommendations for how extension headers can utilise options to extend IPv6

Measuring Roaming in Europe: Infrastructure and Implications on Users QoE

"Roam like Home" is the initiative of the European Commission to end the levy of extra charges when roaming within the European region. As a result, people can use data services more freely across Europe. However, the implications of roaming solutions on network performance have not been carefully examined yet. This paper provides an in-depth characterization of the implications of international data roaming within Europe. We build a unique roaming measurement platform using 16 different mobile networks deployed in 6 countries across Europe. Using this platform, we measure different aspects of international roaming in 4G networks in Europe, including mobile network configuration, performance characteristics, and quality of experience. We find that operators adopt a common approach to implement roaming called Home-routed roaming. This results in additional latency penalties of 60 ms or more, depending on geographical distance. This leads to worse browsing performance, with an increase in the metrics related to Quality of Experience (QoE) of users (Page Load time and Speed Index) in the order of 15-20%. We further analyze the impact of latency on QoE metrics in isolation and find that the penalty imposed by Home Routing leads to degradation on QoE metrics up to 150% in case of intercontinental roaming. We make our dataset public to allow reproducing the results
