             draft-rein-remote-attestation-nfv-use-cases-01

Abstract

   This document proposes the use cases on an architectural level in

1.  Introduction

1.1.  Stakeholders

   Stakeholders play a major role in NFV and there is a strict
   hierarchical separation between the stakeholders in terms of
   responsibility, accessibility and visibility within the the NFV
   architecture.  Although these issues are also relevant for other
   virtualized environments, for example in private or hybrid clouds,
   they are most apparent in NFV, especially in multi vendor
   deployments.

   The stakeholders in NFV are:

   o  Cloud Service Provider (CSP): The CSP provides the platform, i.e.
      the hardware and core services, acting as the Virtual Machine
      Manager (VMM) or hypervisor for the provisioning of Virtual
      Machines (VM).  With regard to this document, the CSP is not
      responsible for the provisioning itself.  The CSP only provides
      the platform w.r.t. to CSP NFV Infrastructure (CSP:NFVI) role.
      The actual provisioning of specific VMs is carried out by the CSP
      Management and Orchestration (CSP:MANO) role, whereas both roles
      may be represented by the same or different organizations.  This
      contribution, however, is not concerned with the internal
      operations and procedures of the CSP:MANO and therefore does
      address CSP:MANO neither as a role nor as a functional component.

   o  Cloud Service Customer (CSC): The CSC is the actual user of the
      VMM and requests the provisioning of specific VMs that eventually
      provide some service.  The CSC is also in full control in terms of

      which specific VM is actually launched and thus not constrained in
      this regard.
