Welcome to the July issue of Computer Communications Review. Over the past months we have tried to make CCR a resource where our community publishes fresh new ideas, expresses positions on interesting new research directions, as well as reports back on community activities, like workshops and regional meetings. In addition, we have introduced the student advice column and the column edited by our industrial board aiming to provide a clearer bridge between scientific practice and technology in commercial products. I am really proud to see all these additions being embraced by the community. This issue features three technical papers, two on cloud computing and one on TCP. Our sincerest thanks to all the authors that submit technical contributions to CCR. And my personal thanks to the tireless editorial board that always aims towards outstanding quality while providing constructive feedback for the continuous improvement of the submitted manuscripts. The editorial zone features three papers as well. One reports on the workshop on Internet economics that took place late last year. The other two cover (i) research challenges in multi-domain network measurement and monitoring, and (ii) the lessons learnt from using RIPE’s ATLAS for measurement research. I hope that both editorials will provide useful insights to the CCR audience. Our industrial column features a contribution from Akamai. The authors describe how research in our community has influenced the design of the content delivery network (CDN) of Akamai, as well as the practical realities they had to deal with to create that bridge between academic output and a scalable, robust content delivery network that serves trillion of requests per day. This issue is coming one month before the annual SIGCOMM conference, that will take place in London in August. Since a couple of years ago, SIGCOMM is the venue where CCR is presenting its "best-of" papers for the previous four issues (July 2014 to April 2015). I am really happy to announce the following two "best of CCR" papers for the year 2014-2015. Technical paper: "Programming Protocol-Independent Packet Processors", by P. Bosshart (Barefoot Networks), D. Daly (Intel), G. Gibb (Barefoot Networks), M. Izzard (Barefoot Networks), N. McKeown (Stanford University), J. Rexford (Princeton University), C. Schlesinger (Barefoot Networks), D. Talayco (Barefoot Networks), A. Vahdat (Google), G. Varghese (Microsoft), and D. Walker (Princeton University). Editorial paper: "A Primer on IPv4 Scarcity", by P. Richter (TU Berlin/ICSI), M. Allman (ICSI), R. Bush (Internet Initiative Japan), and V. Paxson (UC Berkeley/ICSI). Congratulations to the authors of the two best papers and I am really looking forward to seeing all of you in London in August.
