摘要:

SDN/NFV架构中虚拟网络功能(VNF,virtual network function)的性能受限问题,使VNF的硬件加速机制成为研究热点。在部署硬件加速资源后,如何实现对硬件加速资源的统一管控和最优编排是亟待解决的问题。首先,提出了基于分离式控制的硬件加速资源统一管控架构;然后,将传统网络资源和硬件加速资源统一到网络模型中,并将硬件加速资源编排问题建模成基于线性约束的多目标优化问题;最后,设计了加速卡优先部署的启发式算法对问题进行求解。实验结果表明,与现有研究相比,所提机制能有效整合硬件加速资源,降低了近30%的处理时延。

Abstract:

The hardware acceleration mechanism for VNF (virtual network function) is recently a hot research topic in SDN/NFV architecture because of the low processing performance of VNF.Once hardware acceleration resources have been plugged into the network,how to optimally mange and orchestrate these resources under service requirements remains a question to be solved.Firstly,a unified management architecture based on separated control for hardware acceleration resources was proposed.Then,traditional network topology together with hardware acceleration resources were modeled into a unified network model and then the hardware acceleration resource orchestration problem was transferred into a multi-objective linear programming problem.Finally,a hardware-accelerator-card-prior’ heuristic algorithm was designed.Experimental results show that compared with existing methods,the proposed orchestration mechanism can efficiently manage hardware acceleration resources and reduce the processing latency by 30%.

Key words: SDN/NFV, virtual network function, hardware acceleration, resource orchestration
