Abstract
Techniques are described for automatic discovery of two or more virtual service instances configured to apply a given service to a packet in a software-defined networking (SDN)/network functions virtualization (NFV) environment. Virtual service instances may be deployed as virtual entities hosted on one or more physical devices to offer individual services or chains of services from a service provider. The use of virtual service instances enables automatic scaling of the services on-demand. The techniques of this disclosure enable automatic discovery by a gateway network device of virtual service instances for a given service as load balancing entities. According to the techniques, the gateway network device automatically updates a load balancing group for the given service to include the discovered virtual service instances on which to load balance traffic for the service. In this way, the disclosed techniques provide auto-scaling and auto-discovery of services in an SDN/NFV environment.
