A typical SD-WAN solution consists of multiple components for the management, control, and data plane. Proxy services are required for data plane endpoints to communicate with OAM components across multiple underlay networks or routing domains. Separation of traffic across multiple routing domains is key to supporting a multi-tenant solution with multiple underlay networks. High availability and security are paramount requirements for communication between the external (WAN) and internal (management LAN).
This talk describes how HAProxy is used in Nuage’s SD-WAN solution to provide a secure HA mechanism for communication across the internal and external components. We will discuss how the scalable load-balancing capability of HAProxy can be used to support additional value-added services for SD-WAN and how HAProxy monitoring capabilities can be used to provide a health monitoring system for the OAM services.
