摘要

NFV与SDN共同承诺通过将网络功能(NFs)与物理网络拓扑和设备解耦,提供更加灵活高效的业务提供方式,但需要对业务功能链(SFC)进行实时、自动的组合和验证。然而,目前大多数sfc仍然是通过手动配置过程构建的,这是缓慢且容易出错的。在本文中,我们提出了一个新的SFC合成框架,称为自动合成工具包(ACT)。它旨在自动检测NFs之间的依赖关系和冲突,以便在物理基础设施上强制执行sfc之前编写和验证sfc。

Enabling automatic composition and verification of service function chain
NFV together with SDN promises to provide more flexible and efficient service provision methods by decoupling the network functions (NFs) from the physical network topology and devices, but requires the real-time and automatic composition and verification for service function chain (SFC). However, most of SFCs today are still typically built through manual configuration processes, which are slow and error prone. In this paper, we present a novel SFC composition framework, called Automatic Composition Toolkit (ACT). It aims to automatically detect the dependencies and conflicts between NFs, so as to compose and verify SFCs before they are enforced on the physical infrastructure.
