Main Principles for ONAP VNF Package CSAR Current Open-O CSAR is old based on xml-based TOSCA We need to implement a migration path to a new Telcograde VNF package format – ETSI GS NFV-SOL 004 standard, Consensus for CSAR format for ONAP R 1 is reached in https: //wiki. onap. org/pages/viewpage. action? page. Id=10781 062 Introducing a YAML-like Manifest file at the root of CSAR Key directory for all artifacts Adding digests for all artifacts (internal and external) Adding a CMS certificate signature – Optional for R 1

Items covered in ETSI GS NFV-SOL 004 CSAR Formats and how to use them Naming Conventions and Location for • Manifest file • Change History file • Testing files directory • Licensing information directory • Certificate files Security Features of the CSAR • Digests • Signature • Certificates • Encryption 4 © ETSI 2016.

VNF Package The VNF Package contains: • the VNF descriptor (VNFD) that defines metadata for package onboarding and VNF management, • the software images needed to run the VNF, and • Manifest file that provides package integrity and authenticity • (optional) additional files to manage the VNF (e. g. scripts, vendor-specific files etc. ). The VNF Package is delivered by the VNF provider as a whole and is immutable (protected from modification). The VNF Package or its Manifest file is digitally signed The VNF Package is stored in a repository by the NFVO. The VNF Package can be accessed by VNFM. 5 VNF Package Manifest file VNFD Software image(s) Additional files Reference: - ETSI GS NFV-IFA 011 - ETSI GS NFV-SOL 004

VNF Package Structure: TOSCA YAML CSAR without Metadata File CSAR contains a single yaml (. yml or. yaml) file at the root of the archive – MRF. yaml The yaml file contains a metadata section with template_name and template_version metadata. This file is the CSAR Entry-Definition file The CSAR-Version is defined by the template_version metadata: tosca_definitions_version: tosca_simple_yaml_1_1 metadata: template_name: MRF template_author: Company Name template_version: 1. 0 !----- MRF. yaml(R 1) !----- MRF. mf (R 1) !----- MRF. cert (R 2) !----- Change.

VNF Package Manifest File with Optional security support VNF package metadata A list of blocks each is related to one file in the VNF package, including • Source: artifact URI • Optional Algorithm: name of an algorithm used to generate the hash • Optional Hash: text string corresponding to the hexadecimal representation of the hash 7 Optional Manifest file Signature metadata: vnf_product_name: v.
