Introduction Today there is huge diversity of license management mechanisms across VNF

23、Providers which makes service provisioning and license renewing operations more complex, error prone and time consuming. It also makes it difficult to deal with VNF license usage information for settlement between the Service Provider and the VNF Provider. These issues can be resolved by establishin

24、g a standard NFV license management architecture which will have the following benefits: Speed up provision of VNF service without customizing the license management procedure for each VNF-type or VNF Provider. Simplifying acquisition of VNF license usage information. Reduce licensing errors. Simpli

25、fied license management operations independent of the underlying VNF solution. A guiding principle is to minimize the impact on the existing NFV specifications by identifying the minimum features needed to implement any commercial license management framework typically residing in a separate or high

26、er layer system (e.g. OSS/BSS). In order to provide a standardized licensing mechanism, it is necessary to identify the functional blocks, interfaces, and flows impacted by the requirement to implement any commercial license management framework. ETSI ETSI GR NFV-EVE 010 V3.1.1 (2017-12)6 1 Scope Th

27、e present document studies the features needed within the NFV-MANO framework to support license management for NFV. In this version of the document, a focus is made on the software licenses for VNFs. A set of use cases related to VNF licenses in the NFV environment are described, analyzed and used t

45、the licensee by the licensor. The scope of those rights covers all what the licensee could do with the licensed software in his business processes and which may be subject to authorization by the licensor. Usually, the licensee might copy the software, possibly modify for internal development purpos

46、e, resell the derived software and by the way sublicense the acquired licensed software, distribute it as such or simply deploy and use it to provide services to his customers. The rights can be granted for a delimited period, i.e. subscription-based license or without time limit, i.e. perpetual lic

47、ense. NOTE: This is not limited to NFV software. 4.2 NFV licenses categorization 4.2.1 Introduction Different types of software licenses exist today and many of them can be reused in the context of NFV. A classification is generally made according to the entitlement regarding the reproduction (i.e.

48、copy), distribution and use of the software, which can be different depending on the process of software production and motivations of the licensor, which can be, for example a software editor or an open source community. Table 1 gives a high level classification of software licenses. Table 1: Overa
