Closing Session and Best Paper Award




Call for Papers

The Workshop Pré-IETF/IRTF (WPIETF) is an annual event that aims to foster and expand the Internet Engineering Task Force (IETF) presence in Latin America. The IETF is an international community interested in fulfilling the mission of defining standards that impact the design, use, and management of Internet resources (RFC3935).

Establishing standards for the Internet is long, complex, and requires active participation, particularly of students and researchers. There are many people worldwide actively contributing to the IETF. However, there is a growing need for more fresh participation.

The Latin America and the Caribbean (LAC) region’s attendance has been relatively low due to many potential candidates not knowing about the IETF or not having real incentives to participate. To change this reality, a group of volunteers, emerged from the IETF – LAC group (IETF Latin America and the Caribbean), created the WPIETF workshop in 2014, aiming to improve the LAC region presence in the IETF processes. Besides disseminating information about the IETF, it is important to provide an environment that allows our technicians, students, and researchers to show their proposals in advance to any IETF meeting. In this context, the WPIETF is a technical-scientific forum for setting technicians, students, and researchers to the IETF, where theoretical and practical works have been presented, in addition to talks and panels.

In 2021, in its eighth edition, the WPIETF will be held in Florianópolis – SC, in conjunction with the XLI Congresso da Sociedade Brasileira de Computação (CSBC 2021).

Topics of Interest

The VIII WPIETF invites practitioners and researchers to submit technical papers reporting original research and experience results that fit into at least one of the seven areas of interest of the IETF. They are:

  • Applications and Real-Time Area (art): application protocols and architectures, such as e-mail and the Web;
  • General Area (gen): activities focused on supporting, updating and maintaining the IETF standards or that do not fit into any of the available areas;
  • Internet Area (int): include IP layer (both IPv4 and IPv6), implications of IPv4 address depletion, co-existence between the IP versions, and so forth;
  • Operations and Management Area (ops): operation, monitoring, and configuration of networks;
  • Routing Area (rtg): routing protocols and packet routing to your destination;
  • Security Area (sec): security and privacy;
  • Transport Area (tsv): development of data transport protocols for special packages.

Moreover, works in computer networks will also be considered, with themes that do not fit in the official areas and preferably include topics related to the IRTF research groups. They are:

  • CFRG: Crypto Forum Research Group
  • COINRG: Computation in the Network Research Group
  • DINGR: Decentralized Internet Infrastructure Proposed Research Group
  • GAIA: Global Access to the Internet for All Research Group
  • HRPC: Human Rights Protocol Considerations Research Group
  • ICCRG: Internet Congestion Control Research Group
  • ICNRG: Information-Centric Networking Research Group
  • MAPRG: Measurement and Analysis for Protocols Research Group
  • NMRG: Network Management Research Group
  • NWCRG: NetWork Coding for Efficient Network Communications Research Group
  • PANRG: Path Aware Networking Proposed Research Group
  • PEARG: Privacy Enhancement and Assessments Research Group
  • QIRG: Quantum Internet Research Group
  • T2TRG: Thing-to-Thing Research Group

Important Dates

  • Paper submission deadline: March 12 March 26 April 16, 2021 (hard).
  • Notification of acceptance: April 30 May 21, 2021.
  • Camera-ready version: May 15 June 4, 2021.
  • CSBC 2021: July 18-23, 2021.

Submission Instructions

Authors must submit Full Papers (limited to 14 pages) or Short/Abstract Papers (limited to 6 pages). The maximum number of pages includes an abstract, figures, diagrams, references, and attachments. The committee also reserves the right to accept texts submitted in the full article category as a short article. The text can be written in Portuguese, Spanish, or English, following the formats (LaTeX and Word) available on the SBC website (download link).

Each paper must be submitted in PDF via the Web submission form at the JEMS system (link for submission). Authors are highly encouraged to publish software and data sets as open source/data.

Review Process and Publication

All submitted manuscripts will follow a double-blinded review process and subsequent judgment. In this context, all the authors’ names and affiliations must not be present in the submitted manuscript. Submissions will be judged on correctness, originality, technical strength, significance, quality of presentation, and interest and relevance to the workshop scope. Authors have the option of attaching supplemental material, such as source code, to the article. However, this material will not be part of the assessment.

Those articles with the best qualifications will be selected to compose the proceedings and presented at the event. The registration of at least one author of the paper is mandatory to insert the paper in the proceedings.

Besides, all works presented at the WPIETF will have the possibility to be adapted or complemented, if necessary, and forwarded to the IETF, with adequate support (by the Post-WPIETF Committee).

Best Paper Award

In this edition, through the support of Huawei, the best paper will be awarded a trip to participate in the 112 IETF meeting, which will be held November 6-12, 2021, in Madrid, Spain. The award will be given to a single author, preferably the first author. The benefits will be:

  • Airplane Tickets;
  • Event Registration;
  • Accommodation.

Besides, the best paper authors will be invited to submit an extended version for an edition of the Journal of Network and Systems Management (JNSM), impact factor 2.250.

The steering committee will evaluate the works. The main criteria for selecting the best paper, in addition to scientific rigor and contributions, will be the potential to become an IETF draft and later an RFC.
