BFE (Beyond Front End) is a modern layer 7 load balancer from baidu.

Introduction

BFE opensource project includes several components, which can be used together as a integrated layer 7 load balancer and traffic management solution.

BFE system consists of data plane and control plane:

Data plane：responsible for forwarding user's traffic, including below component:
- BFE Server：BFE forward engine (this repository, bfenetworks/bfe). BFE Server performs content based routing, load balancing and forwards the traffic to backend servers.
Control plane：responsible for management and configuration of BFE system, including below components:
- API-Server：provides API and handles update, storage and generation of BFE config
- Conf-Agent：component for loading config, fetches latest config from API-Server and triggers BFE Server to reload it
- Dashboard：provides a graphic interface for user to manage and view major config of BFE
