Thanks for the review Chiradeep. Sure, GSLB service, is indeed cross-zone service, does not fit in to NetWorkElement model. I will by-pass using NetWorkElement, and let GSLB orchestration send commands directly to agent representing the GSLB provider. > >It does not even participate in the existing Loadbalancer workflow. > >In fact I would assert that this is a completely different higher-level >orchestration workflow that should not need to touch network elements or >the network manager. >You could even write this feature by orchestrating it using the end-user >APIs. Agreed. GSLB orchestration need not be part of network manager, I will restrict it to service layer.
