论文摘要
服务功能链（SFC）是一个趋势范式，它有助于在电信网络中引入看不见的灵活性。网络服务提供商以及大型网络基础架构提供商正在竞争为客户提供个性化服务。因此，增加的价值服务需要调用称为服务功能（SFS）的各种基本功能。 SFC概念构成并强加了为特定服务调用SFS的顺序。软件定义网络和网络功能诸如虚拟化等新兴技术支持SFC的动态创建和管理。即使SFC是一个活跃的技术领域，目前已经部署了几个方面，并且已经部署了许多SFC体系结构的口味，但仍有一些挑战和开放问题仍有要解决。在本文中，我们提出了与SFC相关的不同研究问题，并研究了应解决的几个关键挑战，以实现更可靠的SFC操作。
Service Function Chaining (SFC) is a trending paradigm, which has helped to introduce unseen flexibility in telecom networks. Network service providers, as well as big network infrastructure providers, are competing to offer personalized services for their customers. Hence, added value services require the invocation of various elementary functions called Service Functions (SFs). The SFC concept composes and imposes the order in which SFs are invoked for a particular service. Emerging technologies such as Software Defined Networking and Network Function Virtualization support the dynamic creation and management of SFC. Even though SFC is an active technical area where several aspects were already standardized and many SFC architecture flavors are currently deployed, yet some challenges and open issues are still to be solved. In this paper, we present different research problems related to SFC and investigate several key challenges that should be addressed to realize more reliable SFC operations.
