摘要

摘要设计高效灵活的虚拟网络功能(VNF)链布局方法是网络功能虚拟化(NFV)的主要成功。然而,当前的大多数工作在网络中部署VNF时都考虑了恒定的带宽和流处理要求。在具有高度动态流量的支持NFV的网络中,恒定(不可变)流量处理和带宽要求成为关键限制。因此,网络中存在点(PoP)的带宽要求和可用资源不断变化。为了克服这一限制,我们提出了一个用于放置VNF链的自适应模型。同时,所提出的模型最小化了网络中的变化数量(即VNF的重新分配)。实验评估表明,自适应模型能够提供稳定的网络服务。此外,它减少了网络中的大量更改,并确保了流性能。

APVNFC: Adaptive Placement of Virtual Network Function Chains
Abstract Designing efficient and flexible approaches for placement of Virtual Network Function (VNF) chains is the main success of Network Function Virtualization (NFV). However, most current work considers the constant bandwidth and flow processing requirements while deploying the VNFs in the network. The constant (immutable) flow processing and bandwidth requirements become critical limitations in an NFV-enabled network with highly dynamic traffic flow. Therefore, bandwidth requirements and available resources of the Point-of-Presence (PoP) in the network change constantly. We present an adaptive model for placing VNF chains to overcome this limitation. At the same time, the proposed model minimizes the number of changes (i.e., re-allocation of VNFs) in the network. The experimental evaluation shows that the adaptive model can deliver stable network services. Moreover, it reduces the significant number of changes in the network and ensures flow performance.
