    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 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 
    ( 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

    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, 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)

    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.

    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.

During the last half century, the networking field has evolved a lot and SIGCOMM Computer Communication Review (CCR) contributed to this evolution by timely disseminating technical papers. CCR will celebrate SIGCOMM’s birthday with a special issue that will contain editorial notes that reflect on both the past and the future of your SIG. This special issue will be published in October 2019. Its detailed content is still being worked on, but we expect that you will find lots of interesting information in this issue. If you plan to submit papers to CCR, please note that the October 2019 issue will not publish any new technical paper. All the papers submitted between March 1st, 2019 and September 1st, 2019 will be considered for the January 2020 issue.
    This January 2019 issue contains one technical paper and four editorial notes. In “Parametrized Complexity of Virtual Network Embeddings: Dynamic & Linear Programming Approximations”, Matthias Rost et al. analyse the problem of mapping a virtual network on a physical one. They propose both theoretical experimental results.
    The first two editorial notes are position papers addressing different technical topics. In “Network Telemetry: Towards A Top-Down Approach”, Minlan Yu argues that we should view network telemetry from a different angle. Instead of using a bottom-up approach that relies on passively collecting data from various devices and then inferring the target network-wide information, she suggests a top-down approach and envisions the possibility of providing high- level declarative abstractions that would enable operators to define specific measurement queries. This editorial note could be of interest for many Internet measurement researchers.
    In “Thoughts on Load Distribution and the Role of Programmable Switches”, James McCauley and his colleagues take a step back at some usages of programmable network switches. More precisely, they wonder which type of functionality should be migrated to switches and which functionality should not. This is a very interesting question that should be answered when writing the motivation for many papers on programmable switches.
    The two other editorial notes were prepared at a recent Dagstuhl seminar that focused on the reproducibility of network research. In “The Dagstuhl Beginners Guide to Reproducibility for Experimental Networking Research”, Vaibhav Bajpai and his eight co-authors have assembled a very interesting and very useful guide filled with hints and recommendations for young researchers who begin to experiment with networks. This article will probably soon become a must read in many graduate schools. During the same seminar, another group of researchers lead by Alberto Dainotti brainstormed about our x pages two column papers. This format was interesting when articles were disseminated on real paper. Today, thirty years after the invention of the web, there are many other possibilities to disseminate scientific information. Many of these techniques are more collaborative and open than putting pdf files on web servers. “Open Collaborative Hyperpapers: A Call to Action” encourages the measurements community to collaborate on the preparation of hyperpapers. This editorial note explains the motivations for these hyperpapers and discusses some solvable technical challenges. An interesting point about this approach is that it could encourage both a faster dissemination of research results and a truly open model that encourages authors to collaborate. While brainstorming about the 50th birthday issue of SIGCOMM, we had an interesting teleconference with Vint Cerf who reminded us of the role that SIGCOMM Computer Communication played in allowing a fast dissemination of recent research results. He compared CCR with publications such as the Journal of the ACM that had much longer publication delays.
    The hyperpapers in the last editorial note of this issue could be a modern way of disseminating important research results. I would love to see researchers collaborating on hyperpapers in the coming months and submitting their work to CCR. Such a submission would violate the CCR submission guidelines that still assume that authors provide pdf files. If such an hyperpaper gets submitted to CCR, we will find a suitable reviewing process within the CCR Editorial board.


    ACM SenSys 2020 Call for Hosting Proposals
    On behalf of the ACM SenSys Steering Committee, please find below the ACM SenSys 2020 Call for Hosting Proposals
    The Steering Committee of ACM Conference on Embedded Networked Sensor Systems (SenSys, calls for proposals on hosting the 2020 edition of the conference. SenSys is a highly selective, single-track forum for the presentation of research results on sensing systems, broadly defined. In addition to the core technical program, the conference also features poster and demo sessions, workshops, and a PhD forum. It typically draws ~200 attendees from universities, industrial, and government organizations around the world.
    The proposals will be considered in two phases. First, we call for pre-proposals that include:
    - Proposed city information, including local natural and cultural attractions.
    - A short description of local research and education communities related to SenSys.
    - Expected weather and transportation conditions around early November.
    - Type of conference facility in mind: university campus vs hotels.
    - Key organizers, such as General Chair and Local Arrangement Chair, and their experience organizing similar events.
    - Any additional information that may help the steering committee to make decisions.
    For entries that generate enough interests, the steering committee will further solicit full proposals that provide additional information, such as:
    - Possible facility setting, especially space arrangements for main program, demos and posters, and workshops.
    - Attendee cost estimate, such as hotel rate and transportation options.
    - Social functions, such as reception and banquet options.
    - Potential financial supports or risks. There is no geographical preference on locations.
    Proposals from all regions are encouraged to submit. Key dates:
    - Deadline for pre-proposals: April 1, 2019.
    - Notification for full proposal requests: April 29, 2019
    - Deadline for full proposals: May 31, 2019
    - Location announcement: business meeting at SenSys 2019
     Please send pre-proposals to

    Call for Papers, Posters & Demos for the ACM SIGCOMM 2019 Workshop on the Evolution, performance, and Interoperability of QUIC (EPIQ 2019)
    The transport protocol QUIC has emerged from a proprietary effort undertaken by Google to a next generation transport protocol being standardized in the Internet Engineering Task Force (IETF). While its original motivation and design was to support next-generation Web traffic using HTTP/3, embedding QUIC into the Internet architecture raises exciting challenges beyond the necessary engineering efforts. Google QUIC has seen deployment and motivated research papers measuring, extending, and evaluating QUIC from various perspectives.
    The ACM SIGCOMM Workshop on the Evolution, Performance, and Interoperability of QUIC (EPIQ) seeks to foster this emerging community. We invite researchers from academia and industry as well as engineers to explore novel ideas and future directions of QUIC and its interaction with applications and networks. This is the second instance of EPIQ, following its debut at ACM CoNEXT 2018. EPIQ solicits two types of submissions for presentation and discussion at the workshop: academic papers and posters & demos.
    The paper submission deadline for all types of submissions is April 15, 2019 (hard). Please see for details.

    Discrimination and harassment are not to be tolerated within the SIGCOMM community. The SIGCOMM CARES – SIGCOMM Committee to Aid REporting on discrimination and haraSsment policy violations is a step forward to prevent and address any form of unacceptable behavior at events associated with the SIG.
    We recognize that reporting discrimination and harassment to a person in authority, e.g., conference chairs, SIG officers, or ACM staff, can be intimidating, especially in the face of an already traumatic experience.  CARES committee members can serve as an alternative and are also intended as a source of advice on how to approach such a situation and ensure it is investigated by ACM. Committee members are available to listen and help anyone who has either experienced or witnessed discrimination and harassment at any event promoted by the SIG, or needs counseling on how to handle it. Committee members will seek to be present in as many SIG events as possible, starting in 2019 with a presence at SIGCOMM, CoNEXT, IMC, and HotNets.  When attending an event in their capacity as CARES members, individuals will wear a badge that clearly identifies them as such. They can also be contacted online to facilitate and schedule initial discussions. The 2019 committee members are, in alphabetical order, Sujata Banerjee, Marinho Barcellos (co-chair), Craig Partridge, Jennifer Rexford, Justine Sherry, and Ellen Zegura (co-chair).

    Call for Abstracts Latin American Student Workshop on Data Communication Networks (LANCOMM 2019)
    The Latin American Student Workshop on Data Communication Networks (LANCOMM 2019) solicits stimulating and original ideas in all aspects of networking research, reflecting the ongoing research efforts of postgraduate students and junior faculty members in the form of 2-page extended abstracts.
    We encourage submissions about research at an early stage as well as more advanced dissertation-level research. Accepted presentations will not be published as proceedings, so postgraduate students can submit already accepted/published dissertation-level results and conversely results presented at the workshop can subsequently be submitted, in more complete form, for publication in a full-fledged conference or journal. Research addressing non-standard topics, controversial problems and approaches are of particular interest.
    The scope of the workshop is broad and covers all aspects of networking research.. 
    To prepare the extended abstract, please follow the ACM SIGCOMM formatting guidelines (LaTeX template for ACM conference proceedings), except for the following two differences:

    1. papers are limited to TWO (2) pages only, plus references. Note that the two-page limit includes ALL figures, tables but does not include references (add as many as needed);
    2. Please provide only author names and affiliations; it is not necessary to add PAPER ID and number of pages. Submissions must not be anonymous.

    Travel grants will be available to students and postdocs attending LANCOMM 2019. This support, provided by SIGCOMM, will assist a substantial number of attendees by covering their transport and accommodation costs. The request must be made together with the submission of the extended abstract.
