The present document defines the protocol and data model for the following interfaces used over the Ve-Vnfm reference point, in the form of RESTful Application Programming Interfaces (APIs) specifications:

• VNF Lifecycle Management interface (as produced by the VNFM towards the EM/VNF).
• VNF Performance Management interface (as produced by the VNFM towards the EM).
• VNF Fault Management interface (as produced by the VNFM towards the EM).
• VNF Indicator interface (as produced by the EM/VNF towards the VNFM).
• VNF Configuration interface (as produced by the VNF towards the VNFM).

The present document specifies common aspects of RESTful protocols and data models for ETSI NFV management and orchestration (MANO) interfaces.

The present document specifies the YANG models for representing Network Functions Virtualisation (NFV) descriptors, fulfilling the requirements specified in ETSI GS NFV-IFA 011 and ETSI GS NFV-IFA 014 applicable to a Virtualised Network Function Descriptor (VNFD), a Physical Network Functions Descriptor (PNFD) and a Network Service Descriptor (NSD).

The present document specifies the structure and format of a VNF package file and its constituents, fulfilling the requirements specified in ETSI GS NFV-IFA 011 for a VNF package.
 
The present document also specifies the structure and format of a PNFD archive file and its constituents, fulfilling the requirements specified in ETSI GS NFV-IFA 014 for a PNFD archive.

The goal of TC CLOUD is to address issues associated with the convergence between IT (Information Technology) and Telecommunications. The focus is on scenarios where connectivity goes beyond the local network. This includes not only Cloud computing but also the emerging commercial trend towards Cloud computing which places particular emphasis on ubiquitous network access to scalable computing and storage resources.
 
Since TC CLOUD has particular interest in interoperable solutions in situations which involve contributions from both the IT and Telecom industries, the emphasis is on the Infrastructure as a Service (IaaS) delivery model. TC CLOUD focuses on interoperable applications and services based on global standards and the validation tools to support these standards. Evolution towards a coherent and consistent general purpose infrastructure is envisaged. This will support networked IT applications in business, public sector, academic and consumer environments.
 
The approach is to complement existing activities in ETSI and other standards development organisations. TC CLOUD is expected to fulfil a specific role as a forum in which to develop consensus within the telecommunications sector which can then be represented in other bodies. It can also act to introduce new requirements into networking (e.g. NGN) standards which support new application paradigms such as Grid and Cloud.

ISG NFV has developed over 80 different reports and specifications for the virtualisation of network functions. NFV publications describe and specify virtualisation requirements, architecture framework, functional components and their interfaces, as well as the protocols and the APIs for these interfaces. ISG NFV also studies VNF performance, reliability, and resiliency matters, analyses the security challenges linked to virtualisation (trust, attestation, regulation). NFV specifies requirements for Management and Orchestration, for hardware acceleration, etc. And a lot is ongoing!

The present document specifies a set of RESTful protocols and data models fulfilling the requirements specified in ETSI GS NFV-IFA 031 for the interfaces that enable the management of NFV-MANO functional entities.
It defines the protocol and data model for the interfaces used for the management of NFV-MANO functional entities, in the form of RESTful Application Programming Interface (APIs) specifications:

• NFV-MANO configuration and information management interface;
• NFV-MANO performance management interface;
• NFV-MANO fault management interface;
• NFV-MANO state management interface;
• NFV-MANO log management interface. The interfaces are produced by the NFV-MANO functional entity, which acts as API producer, and can be consumed by an authorized external entity, which acts as API consumer. For more information, clause 4.2 of ETSI GS NFV-IFA 031 defines the framework for the management of NFV-MANO.

The present document defines the protocol and data model for the following interfaces, in the form of RESTful Application Programming Interface (APIs) specifications:

• NSD Management interface (as produced by the NFVO towards the OSS/BSS)
• NS Lifecycle Management interface (as produced by the NFVO towards the OSS/BSS)
• NS Performance Management interface (as produced by the NFVO towards the OSS/BSS)
• NS Fault Management interface (as produced by the NFVO towards the OSS/BSS)
• VNF Package Management interface (as produced by the NFVO towards the OSS/BSS)

The present document specifies the structure and format of a VNF package file and its constituents, fulfilling the requirements specified in ETSI GS NFV-IFA 011 for a VNF package.
 
The present document also specifies the structure and format of a PNFD archive file and its constituents, fulfilling the requirements specified in ETSI GS NFV-IFA 014 for a PNFD archive.
