    CCR is SIGCOMM's newsletter.  It is published quarterly and publishes 
    both peer-reviewed technical papers and non-peer reviewed editorial 
    content.  It also serves as a forum for the publication of reports from 
    SIG's sponsored workshops and conferences, and as of 2012 the best of 
    CCR papers appear for presentation at ACM SIGCOMM. Publication of the 
    newsletter is overseen by the CCR Editor with the help of an Editorial 
    Board consisting of Area Editors.  The CCR editor manages the paper 
    submission, review, and publication process together with the Editorial 
    Board.  Reviews are currently managed through hotcrp.com and papers are 
    published on both the ACM DL and CCR Online, although the latter may end 
    now that access to CCR papers in the ACM DL is open-access.
    In addition to the above responsibilities, the CCR editor also solicits 
    editorial submissions and over the years has launched a number of 
    initiatives aimed at broadening the impact and scope of CCR.  One such 
    example was the creation of an artifacts evaluation committee tasked 
    with handling artifact submissions either directly or for papers 
    published in some of the SIG's sponsored conferences. Another more 
    recent is the exploration of podcasts, to be hosted on the DL, to 
    commemorate the SIG's 50th birthday.
    The term of the current CCR Editor, Olivier Bonaventure, is coming to an 
    end and the SIGCOMM EC is issuing an open call for nominations to 
    identify his replacement. In addition to continuing the tradition of 
    quality and innovation that has been CCR's trademark, as we move some of 
    the publication aspects into the ACM DL and explore other means of 
    offloading logistical support, the new CCR Editor will have the 
    opportunity to launch new initiatives aimed at best serving the needs of 
    our community.
    Interested candidates should submit by email to the SIG Chair 
    (guerin@acm.org) a short two-page statement highlighting the experience 
    they bring to the position and articulating their vision for the 
    newsletter, a link to a recent CV, and a list of three names that the 
    SIGCOMM EC could contact for references.

    SIGCOMM is ACM's professional forum for discussing communications and 
    computer networks. The SIG sponsors a range of conferences and awards 
    travel grants to attend them, oversees the publication of its 
    newsletter, CCR, and organizes various events for its members, including 
    summer schools and students workshops. In particular, the SIG has a 
    strong tradition of activities aimed at encouraging the participation of 
    students and junior researchers.
    The SIGCOMM Education Director is responsible for coordinating 
    activities aimed at creating educational material and opportunities on 
    various networking topics for students and our members, as well as for 
    soliciting and initiating new activities in those areas. Examples of 
    past such activities include contributions to ACM/IEEE CS Curriculum, 
    organizing shadow TPCs, supporting summer schools, organizing education 
    workshops, initiating the CoNEXT student workshop, editing the SIGCOMM 
    ebook on recent advances in networking, etc.
    The new SIGCOMM Education Director is expected to not only continue 
    coordinating existing educational activities, but also contribute to 
    encouraging and creating new proposals that address the expectations of 
    today's students and teachers. Possible ideas include exploring MOOCs, 
    webinars, improving the quality of wikipedia networking pages, 
    organizing hackathons or education workshops on emerging topics.  The 
    SIG is committed to helping support greater educational initiatives and 
    resources will be made available to help the new Education Director 
    realize them.
    Interested candidates should submit by email to the SIG Chair 
    (guerin@acm.org) a short (one or two pages) statement describing their 
    vision and objectives for this position, a link to a recent CV, and a 
    list of three names that the SIGCOMM EC could contact for references.

    Call for Papers, ACM SOSR 2020
    Call for Papers, Workshop on Buffer Sizing (BS’19)

    Call for Papers, ACM SOSR 2020
    More than 10 years have now elapsed since the beginning of Software-Defined Networking (SDN). Over the course of a decade, SDN has fueled incredible innovation, revolutionizing virtually all networking areas. SDN is now deployed in a growing number of production and experimental settings, including data centers, enterprise networks, content providers, and Internet Service Providers.

    The ACM SIGCOMM Symposium on SDN Research (SOSR) is the premiere venue for research publications on SDN, building on past years' successful SOSR and HotSDN (Hot Topics in Software Defined Networking) workshops. New to this year, SOSR will be co-­located with the Open Compute Project (OCP) Global Summit on March 3, 2020 in San Jose, CA.to foster interaction between academic and industrial attendees.

    We invite submissions on a wide range of research on the broad area of software-defined, programmable networks, and more. 

    Paper registration(with abstract): November 8, 2019 (AoE)
    Paper submission: November 15, 2019 (AoE)
    More details https://conferences.sigcomm.org/sosr/2020/calls.html

    Call for Papers, Workshop on Buffer Sizing 2019 (BS’19)
    Buffer Sizing, Stanford University December 2-3, 2019

    Despite lots of discussion in academia and industry, there isn’t consensus about how big a router buffer should be. Choosing a buffer size is inherently complicated: It depends on (at least) the congestion control algorithm, AQM (marking and dropping policies), load-balancing, traffic engineering and the applications generating the traffic. So far, there has been some measurement and theory, but little consensus.

    Involving academics and industry stakeholders, the goal of this workshop is to improve our understanding of how to pick buffer sizes in different parts of the network (e.g. DC, WAN, last mile, WiFi, cellular), for different applications (video, HPC, Hadoop-like, financial) and for different congestion control algorithms. Ideally, we would like to establish, from a mix of theoretical and experimental results, guidelines that can be used in practice to size routers’ buffers, and provide guidance to semiconductor and equipment providers.

    Register paper or talk proposal on website: Before October 15 at 11.59pm Pacific Time.
    Submit 4-6 page paper or 2 page proposal: Before October 22 at 11.59pm Pacific Time.

    July 2019 SIGCOMM Newsletter
    SIGCOMM 50th Anniversary panel
    Announcing changes to the SIGCOMM Executive Committee
    Computer Communication Review (The ACM Newsletter), The July 2019 Issue

    SIGCOMM 50th Anniversary panel
    As part of the commemoration of the 50th anniversary of SIGCOMM, a panel discussion on "Past and Future Directions in Networking Research" will be held during the first session of the SIGCOMM conference on Wednesday, August 21. The panel will start with a brief introductory video by Vint Cerf before opening up to discussions with our panelists. The panelists will be Dah Ming Chiu (Chinese University of Hong Kong), Manya Ghobadi  (Massachusetts Institute of Technology), Mark Handley (University College, London) , Jennifer Rexford (Princeton University), and Lixia Zhang (University of California at Los Angeles), and the discussion will be moderated by Bruce Maggs (Duke University and Akamai Technologies).

    Announcing changes to the SIGCOMM Executive Committee
    After serving for a little over two years as SIGCOMM vice-chair, Aditya Akella has asked to step down.  We would like to thank him for his efforts in promoting the SIG and advancing its agenda during that period.  It represents a non-trivial amount of time and energy.
    As per the SIG's bylaws regarding vacancies and appointments, in such instances the board is tasked with selecting a replacement, and while we are sad to see Aditya go, we are delighted to announce that Sujata Banerjee has agreed to serve as the new SIG vice-chair. 
    Please join us in thanking Aditya for his service and welcoming Sujata in her new role.

    Computer Communication Review (The ACM Newsletter), The July 2019 Issue
    This July 2019 issue contains two technical papers and three editorial notes. In ”Securing Linux with a Faster and Scalable IPtables”, Sebastiano Miano and his colleagues revisit how Linux firewalls work. Since version 2.4.0 of the Linux kernel, iptables has been the standard way of defining firewall rules in Linux. These iptables are widely used, but writing and maintaining them can be difficult. Furthermore, they have some limitations in terms of performance. This paper leverages the eBPF virtual machine that is included in the Linux kernel to propose a replacement for iptables that preserves their semantics while providing im- proved performance. They release their implementation and evaluate its performance in details.
    In ”Towards Passive Analysis of Anycast in Global Routing: Unintended Impact of Remote Peering”, Rui Bian et al. analyse the deployment of anycast services. For this, they rely on different BGP routing information and highlight the impact of remote peering on anycast performance. They release their data and analysis scripts.
    In addition to these two peer-reviewed papers, this issue contains three editorials. In ”Privacy Trading in the Surveillance Capitalism Age: Viewpoints on ‘Privacy- Preserving’ Societal Value Creation”, Ranjan Pal and Jon Crowcroft reconsider the current Mobile App ecosystem from an economical and privacy viewpoint. They show that the current model is not the only possible one and propose the idea of a regulated privacy trading mechanism that provides a better compromise between privacy and the commercial interests of companies. In ”Datacenter Congestion Control: Identifying what is essential and making it practical”, Aisha Mushtaq et al. take a step back at the datacenter congestion control problem. They argue that congestion control mechanisms that use Shortest-Remaining- Processing-Time are the best solution and discuss in the paper how commodity switches could be modified to support it. Finally, in ”The 11th Workshop on Active Internet Measurements (AIMS-11) Workshop Report”, kc Claffy and Dave Clark summarise the discussions at the latest AIMS workshop. They mention several new measurement ini- tiatives and interesting research projects.
