..

2. Template Component API definitions

DCAE Component provides the following interfaces:

Interface Name	Interface Definition	Interface Capabilities	Version	Status
DCAE-E1	VES Collector	An interface to share FM/PM data for VNF FCAPS from the VNFs via the EMS Driver to VES Collector	REST	production
DCAE-E2	HV-VES Collector	Interface to support GPB over TCP for highvolume VES Events
DCAE-E3	DataFileCollector	Supports bulk/batch datafile collection from xNF
DCAE-E4	SNMPTrap	Supports SNMP traps collection from SNMP agents deployed in the network	UDP	production
DCAE-E5	RESTConf	Subscribes to external controllers and retrieves data
DCAE-E6	PNF Registration Handler	Retrieves PNF Registration event from PNF through VESCollector/DMAAP Publishes PNF_READY/PNF_UPDATE events on DMAAP
DCAE-E7	Inventory API	DCAE Inventory is a web service that provides the following: Real-time data on all DCAE services and their components Comprehensive details on available DCAE service types	REST	production
DCAE-E8	Deployment Handler	High-level API for deploying/undeploying composed DCAE services	REST	production
DCAE-E9	Acumos Adapter	Retrieves models from Acumos and onboard them into DCAE (MOD) using OnboardingAPI and make it available in Catalog		POC
POE-4	Policy Handler	Fetch policy associated for DCAE MS from Policy Framework	REST	production
POE-5	Policy Handler	Fetched updates policies from the Policy Framework via DMaap

DCAE Component consumes the following Interfaces:

Interface Name	Purpose Reason For Use	Version(s)
POE-1	Sends PDP requests asynchronously via DMaaP
