The Intel ® 2022 P4 China Hackathon explored P4 outstanding talents, improved P4 developers’ innovation capability, and promoted P4 programmable network ecological construction and we are proud to announce the winners of the online final appraisal which took place on November 18th and identified one first prize, four second prizes, five third prizes and two special prize winners (please see list below).

The P4 Hackathon was initiated by Intel® and ONF, and co-organized by Jiangsu Future Networks Innovation Institute (FNII). Since its launch in September, it has drawn interest from teachers and students in universities and research institutes across China, attracting 49 teams from Tsinghua University, Peking University, Fudan University, Shanghai Jiaotong University, Zhejiang University, Nanjing University and other universities and research institutes who participated in the hackathon. The scope of projects encompassed network measurement, transport optimization, in-network computing, in-network storage, AI/ML, Cybersecurity, load balancing and more.

After stringent preliminary review of the project materials, 10 teams were selected as finalists (congratulations to the winners – please see the list below). The hackathon invited well-known domestic and foreign technical experts to participate in the assessment of projects and the format was a 10 minute presentation by project representatives plus 5 minutes of Q&A with the judges. The judging committee included academic and industry experts who based their evaluation on the research field, algorithm innovation, engineering quality and other aspects of each projects coupled with the presentation and defense of each team at the final evaluation meeting. 

Many excellent innovations emerged, some of which will help to foster the adoption of P4 and Intel® Tofino™ Intelligent Fabric Processors in popular application fields, such as network measurement, in-network computing, network function acceleration, etc. Some fundamental algorithm innovations have created the feasibility of P4 and Intel Tofino Intelligent Fabric Processors in a wider range of scenarios.
