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

Refer to Overview in BFE document for more information

Besides, we also implement BFE Ingress Controller based on BFE, to fulfill Ingress in Kubernetes
