Applied Networking Research Prize presentations at IETF 112

27 Oct 2021

The Internet Research Task Force (IRTF) open session at the IETF 112 online meeting will feature presentations on research into routing protocols, the effects of third-party service dependencies, and censorship on the Internet. IETF 112 is scheduled for November 8 to 12.


Applied Networking Research Prize (ANRP) awards are presented each year for recent results in applied networking research relevant to shipping Internet products and related standardization efforts. The ANRP program recognizes the best new ideas in networking and provides them with greater visibility within the IETF and IRTF communities. 

Six people received ANRP awards for 2021. Awards to Francis Y. Yan, Audrey Randall, Rüdiger Birkner, and Sadjad Fouladi were made during IETF 110 and 111. Three additional award winners will present their research at IETF 112.

Thomas Wirtgen will present his work on the extensibility of BGP implementations, and other routing protocols. He, along with Quentin De Coninck, Randy Bush, Laurent Vanbever, and Olivier Bonaventure, first presented “xBGP: When You Can’t Wait for the IETF and Vendors”, during ACM HotNets, 2020. The team looked at the way routers from various vendors are deployed using standardized routing protocols. One problem with this process is that any new feature must be standardized and implemented by all router vendors before it can be deployed.

Wirtgen’s team proposed a “paradigm shift” that enables network operators to program the routing protocols used in their networks. The research group demonstrated the feasibility of this approach with xBGP, a vendor-neutral API.

Aqsa Kashaf will present her work on studying the effects of third-party service dependencies in the Internet. She, along with Vyas Sekar, and Yuvraj Agarwal, presented “Analyzing Third Party Service Dependencies in Modern Web Services: Have We Learned from the Mirai-Dyn Incident?”, at ACM IMC 2020.

The research looks at how many websites rely on third parties for services such as  DNS and CDN. However, this reliance also exposes them to shared risks from attacks or cascading failures. The research analyzed the prevalence and impact of third-party dependencies, focusing on three critical infrastructure services: DNS, CDN, and certificate revocation checking by CA. 

Finally, Kevin Bock will present his work on Internet censorship. He, along with 

George Hughey, Louis-Henri Merino, Tania Arya, Daniel Liscinsky, Regina Pogosian, and Dave Levin, first presented “Come as You Are: Helping Unmodified Clients Bypass Censorship with Server-side Evasion” at ACM SIGCOMM 2020.

The researchers focused on server-side efforts to evade censorship and are the first to present mechanisms to defeat censorship exclusively from the server-side of a connection. They extended their machine learning tool, Geneva, to automate the discovery and implementation of server-side strategies, and successfully applied it to four countries (China, India, Iran, and Kazakhstan) and to five protocols (DNS-over-TCP, FTP, HTTP, HTTPS, and SMTP). 

A live stream of the session on 9 November 2021 at 16:00 UTC.will be available on the IETF YouTube channel

In addition, the organizers of the ANRP have released a call for nominations for the 2022 prize. For more information, go to the ANRP webpage.

The ANRP is supported by the Internet Society and the IRTF, and sponsored by Comcast and NBC Universal.
