摘要

网络功能虚拟化(NFV)通过虚拟化传统上在专用硬件中实现的网络功能,提供了增强服务交付灵活性和降低总体成本的潜力。然而,NFV的灵活性带来了相当大的妥协,因为虚拟机承载的功能可能会带来显著的性能开销。在本文中,我们提出了一种新的高性能框架HYPER,它结合了NFV中的可编程硬件基础设施和传统软件基础设施,以实现高性能和灵活性,以支持虚拟网络功能(VNFs)。在HYPER中,我们设计了一个中介层,对NFV编排器隐藏底层基础设施的异构性,以简化VNF管理。此外,我们在HYPER中设计了一个支持sla的服务链算法,以利用混合基础设施的优势来满足服务订阅者(或租户)的功能和性能需求。为了优化资源利用效率,我们还在HYPER中引入了一个性能敏感的VNF放置算法,该算法在放置VNF时满足资源和性能要求。我们在一个基于OpenStack和ONetCard的测试平台上实现了HYPER。实验结果表明,与基于数据平面开发工具包的实现相比,HYPER在保持VNF管理灵活性的同时,将业务链的转发延迟降低了40% ~ 67%。

HYPER: A Hybrid High-Performance Framework for Network Function Virtualization
Network function virtualization (NFV) offers the potential for both enhancing service delivery flexibility and reducing overall costs by virtualizing network functions that are traditionally implemented in dedicated hardware. However, the flexibility of NFV comes with considerable compromises since virtual machine carried functions could introduce significant performance overhead. In this paper, we present a novel high-performance framework called HYPER, which combines programmable hardware infrastructure and traditional software infrastructure in NFV to achieve both high performance and flexibility for supporting virtualized network functions (VNFs). In HYPER, we design a mediator layer to hide underlying infrastructure heterogeneity from the NFV orchestrator to simplify VNF management. In addition, we design a SLA-aware service chaining algorithm in HYPER to leverage the benefits of the hybrid infrastructure to fulfill both functional and performance requirements from service subscribers (or tenants). To optimize resource utilization efficiency, we also introduce a performance-aware VNF placement algorithm in HYPER, which accommodates both resource and performance requirements in placing VNFs. We implement HYPER in a testbed based on OpenStack and ONetCard. Experimental results show that HYPER reduces the forwarding latency of a service chain by 40% to 67% compared with data plane development kit -based implementation, while maintaining the flexibility of VNF management.
