Enabling SD-WAN Operations Using HAProxy

Gurpreet Singh & Patrick Dumais

A typical SD-WAN solution consists of multiple components for management plane, control plane 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 support a multi-tenant solution with multiple underlay networks. High availability and security is paramount requirement for communication between the external (WAN) and internal (management LAN).

This talk describes how HAProxy is used in the Nuage’s SD-WAN solution to provide a secure HA mechanism to provide the communication across the internal and external SD-WAN 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.
