In-depth Understanding of BFE
English | 中文
This book focuses on BFE open source project, introduces the relevant technical principles of network access, explains the design idea of BFE open source software, and how to build a network front-end platform based on BFE open source software. Readers with development capabilities can also develop BFE extension modules according to their own needs or contribute code to BFE open source projects according to the instructions in this book.
BFE Open Source Project
BFE is Baidu's unified layer-7 load balancing platform. The BFE platform has been under construction since 2012. By the end of 2020, the BFE platform has forwarded more than trillions of requests per day, with a daily peak of more than 10 million QPS, which has great influence in the industry. In July 2019, BFE's forwarding engine was open-sourced, and was accepted by CNCF (Cloud Native Computing Foundation) as the "Sandbox Project" in June 2020.
