“…Research on VPN gateways can be classified into three categories: solutions to network interconnections [15][16][17], assurance of security issues [18,19] and evaluations and improvements of network performance. Evaluations and improvements of network performance range from evaluations of VPN gateways [20][21][22][23][24] and hardware-accelerated VPN gateways [11,12,25,26] to improvements of software VPN gateways [13,[27][28][29].…”

Virtual private network (VPN) gateways are widely applied to provide secure end-to-end remote access and to relay reliable interconnected communication in cloud computing. As network convergence nodes, the performance of VPN gateways is limited by traditional methods of packet receiving and sending, the kernel protocol stack and the virtual network interface card. This paper proposes a generic high-performance architecture (GHPA) for VPN gateways in consideration of its generality and performance. In terms of generality, we redesign a generic VPN core framework by modeling a generic VPN communication model, formulating generic VPN core technologies and presenting corresponding core algorithms. In terms of performance, we propose a three-layer GHPA for VPN gateways by designing a VPN packet processing layer based on a data plane development kit (DPDK), implementing a user space basic protocol stack and applying our proposed generic VPN core framework. On the basis of the research work above, we implement a high-performance VPN (HP-VPN) and a traditional VPN (T-VPN) that complies with GHPA and traditional methods, respectively. Experimental results prove that the performance of HP-VPN based on GHPA is superior to T-VPN and other common VPNs in RTT, system throughput, packet forwarding rate and jitter. In addition, GHPA is extensible and applicable for other VPN gateways to improve their performance.

“…The platform exposes a programming abstraction to give applications direct control over F-NIC accelerators and a I/O path virtualization to let multiple VMs share the F-NIC with guaranteed security and fairness. FlowShader [129], GPUNFV [130], Gen [131], Grus [132], and G-NET [133] seek to construct a concerted CPU-GPU pipeline to expedite SFC processing. FlowShader explores GPU and CPU for paralleled processing.…”

NFV Platform Design: A Survey

Due to the intrinsically inefficient service provisioning in traditional networks, Network Function Virtualization (NFV) keeps gaining attention from both industry and academia. By replacing the purposebuilt, expensive, proprietary network equipments with software network functions consolidated on commodity hardware, NFV envisions a shift towards a more agile and open service provisioning paradigm with much lower capital expenditure (CapEx) and operational expenditure (OpEx). Nonetheless, just as any complex system, NFV platforms commonly consist of abounding software and hardware components, and usually incorporate disparate design choices based on distinct motivations or use cases. This broad collection of convoluted alternatives makes it extremely arduous for network operators to make proper choices. Although numerous efforts have been devoted to investigating different aspects of NFV, none of them specifically focused on NFV platforms or attempted to explore the design space. In this paper, we present a comprehensive survey on NFV platform design. Our study solely targets existing NFV platform implementations. We begin with an architectural view of the standard reference NFV platform and present our taxonomy of existing NFV platforms based on principal purpose of design. Then we thoroughly explore the design space and elaborate the implementation choices each platform opts for. We believe that our study gives a detailed guideline for network operators or service providers to choose the most appropriate NFV platform based on their respective requirements.
