Hi Architecture sub-com, (Apologies, resending to correct email address for arc sub-comm list).
Referring to AAI meeting notes: https://wiki.onap.org/display/DW/2018-07-25+AAI+Weekly+Meeting+Notes And Figure 5 and 6 from https://wiki.onap.org/display/DW/AAI-CCVPN+Schema+Proposal+for+Casablanca+Release The CCVPN use case involves two separate ONAP domains (e.g. one for CMCC and the other for VDF), with the end-to-end service connecting the two networks together (see Figure 5 from link above). In the middle of this service, we propose to represent the inter-network connection as "logical-link" object between two "p-interface" objects. In this use case, however, one "p-interface" object is in the CMCC ONAP domain and the other "p-interface" object is in the VDF ONAP domain. The "logical-link" object needs to span both ONAP domains. Questions: - Is there an existing/preferred architectural pattern or design pattern for how to record this situation in AAI? - Is there a protocol for federating the AAI data from two different ONAP domains? The AAI meeting briefly discussed how the new "enricher" component should work in Casablanca. We have made a tentative proposal shown in Figure 6 from the link above, whereby: - a "foreign-object" is recorded in AAI for each ONAP domain, e.g. to represent the other "p-interface" - some "ESR info" is attached to the "foreign-object" pointing to the other ONAP domain as the "source of truth" for that object - the "foreign-object" may cache some of the properties sourced from the other ONAP domain - both ONAP domains have AAI data pointing to each other in mirror-image fashion We are seeking review comments and guidance on how best to proceed with recording this cross-domain data into AAI in both ONAP domains.
