Abstract:

Promise is an OPNFV requirement project. Its objective is to realize ETSI NFV defined resource reservation and NFVI capacity features within the scope of OPNFV. Promise provides the details of the requirements on resource reservation, NFVI capacity management at VIM, specification of the northbound interfaces from VIM relevant to these features, and implementation plan to realize these features in OPNFV.
