近年来，电信格局正在经历重大转变。最初的软件定义网络 (SDN)，后来的网络功能虚拟化 (NFV) 开辟了新的方式来应对日益增长的服务提供商场景。对所提供服务的描述将是决定不同提案的集成和互操作性是否成功的关键点。然而，对未来场景及其要求的深入理解最近给充分实现 NFV 愿景的好处带来了独特的挑战。在本文中，我们回顾了与 NFV 领域相关的主要举措中的服务描述提案。然后我们详细阐述关键的新挑战并评估不同的提案如何解决这些挑战。最后，我们提出了一个服务和资源描述的稻草人模型，以解决这些挑战，并定义可作为本主题未来计划和更新的设计方向的功能。
The telecommunications landscape has been undergoing a major shift in recent years. Initially Software Defined Networking (SDN), and then Network Function Virtualization (NFV) have opened up new ways of looking at the increasingly demanding service provider scenario. The description of the service to be provided will be a key point determining the success in the integration and interoperability of the different proposals. However, the refined understanding of the future scenario and its requirements has recently introduced unique challenges in the path to fully achieve the benefits of the NFV vision. In this paper we review the proposals of service description in the main initiatives related to the NFV arena. Then we elaborate on key novel challenges and evaluate how the different proposals solve them. Finally, we propose a straw man model of service and resource description addressing these challenges and defining the features that would serve as design directions for future initiatives and updates in this topic.
