Robert/Linda, RTGWG chairs have been thinking of starting SD-WAN discussion in RTGWG. Service data modeling(data modeling in general)is an obvious candidate (at ONUG we started, there’s some early effort, but IETF help is needed). Control plane interworking is another interesting topic. Please bring your ideas, I’m still working on agenda
