From 882933502c0eedc219197fa8c39a2cb733ea6729 Mon Sep 17 00:00:00 2001 From: Saravanan A Date: Tue, 9 Oct 2018 16:20:52 +0530 Subject: Add implementation for OOF PCI use case Receive DMaaP message from PCI-Handler MS with PCI Config change recommendations through DCAE_CL_OUTPUT topic. Trigger SDN-R (if allowed by policy) by sending DMaaP request through SDNR-CL topic. When the response is received from SDNR through SDNR-CL-RSP topic, just parse and print. Code review comments addressed Added controller changes into amsterdam too.
