The July 2018 issue

In May, the CCR Editorial board selects the two best papers that were published in the four previous issues (i.e. July 2017, October 2017, January 2018 and April 2018). For 2018, two measurement papers were chosen:

These two papers will be presented during the CCR session at SIGCOMM’18. Both papers have proposed a methodology, collected measurements and released artifacts to allow other researchers to reproduce and extend the paper results. CCR continues to encourage papers to release their artifacts by allowing them to be longer than six pages. SIGCOMM will do one further step to encourage the release of paper artifacts by the creation of an Artifacts Evaluation Committe that will organise the evaluation of the artifacts associated with papers accepted in CCR and the SIGCOMM sponsored conferences in 2018. The final details are still being discussed. They will be announced during SIGCOMM’18 and posted on

This issue starts with three technical articles. In Accelerating Network Measurement in Software, Y. Zhou, O. Alipourfard, M. Yu and T. Yang propose a new technique that leverages caching to improve network measurement software. They release the software
developed for the paper at

Our second technical paper looks at the BGP peerings and more precisely those maintained by the so called Hypergiants, i.e. the larget content providers and CDNs. T. Bottger, F. Cuadrado and S. Uhlig analyse in Looking for Hypergiants in PeeringDB the interconnections of those networks from IXP data. The authors also release the code and the dataset used to write their paper.

The third technical paper of this issue fo- cuses on the Domain Name System. R. AlDalky, M. Rabinovich and M. Allman propose and evaluate in Practical Challenge-Response for DNS a new technique that relies on challenge-responses to validate the authenticity of DNS requests.

In addition to the technical papers, this issue also contains three editorial notes. In Mosaic5G: Agile and Flexible Service Platforms for 5G Research, N. Nikaein, C. Chang and K. Alexandris describe Mosaic5G, an open-source software platform that can be used to create 5G networks. Given the buzz around 5G networks, I expect that many researchers will be interested by this platform. In NDN Host Model, H. Zhang, Y. Li, Z. Zhang, A. Afanasyev and L. Zhang discuss how the traditionnal host model must be reconsidered with Named Data Networking (NDN). Finally, KC Claffy, G. Huston and D. Clark summarise in Workshop on Internet Economics (WIE2017) Final Report the conclusions of a recent workshop that they organised.
