摘要
Systems and methods for dynamic service-based load balancing in an SD-WAN are provided. According to one embodiment, a subnet assigned to a client device by a hub network of the SD-WAN and one or more attributes of a path or a route to a group of clients within the subnet are received by a first process of an SD-WAN controller via a dynamic routing protocol. A tagged subnet is generated by the first process by tagging the subnet with a route tag corresponding to the one or more attributes. The first process informs the SD-WAN of the tagged subnet by communicating the tagged subnet to a second process of the SD-WAN controller via an inter-process communication mechanism. Responsive to receipt of the tagged subnet, the second process translates an SD-WAN service rule defined with reference to the route tag to an SD-WAN service rule defined with reference to the subnet.
