“…The study [52] introduces a strategy for OVS to detect an elephant flow and offload its processing to an NPU so that the overall performance of OVS can be improved. However, as we discussed in Section 2.1, processor-based accelerators hardly meet the scalability requirements for implementation beyond 100 Gbps due to their packet processing architecture.…”

Software-defined networking (SDN) has attracted much attention since it was proposed. The architecture of the SDN data plane is also evolving. To support the flexibility of the data plane, the software implementation approach is adopted. The software data plane of SDN is commonly implemented on a commercial off-the-shelf (COTS) server, executing an entire processing logic on a commodity CPU. With sharp increases in network capacity, CPU-based packet processing is overwhelmed. However, completely implementing the data plane on hardware weakens the flexibility. Therefore, hybrid implementation where a hardware device is adopted as the accelerator is proposed to balance the performance and flexibility. We propose an FPGA SmartNIC-based reconfigurable accelerator to offload some of the operation-intensive packet processing functions from the software data plane to reconfigurable hardware, thus improving the overall data plane performance while retaining flexibility. The accelerated software data plane has a powerful line-rate packet processing capability and flexible programmability at 100 Gbps and higher throughput. We offloaded a cached-rule table to the proposed accelerator and tested its performance with 100 GbE traffic. Compared with the software implementation, the evaluation result shows that the throughput can achieve a 600% improvement when processing small packets and a 100% increase in large packet processing, and the latency can be reduced by about 20× and 100×, respectively, when processing small packets and large packets.

Compared with traditional antenna simulation computing, the cloud computing has many remarkable characteristics, such as high efficiency, low level hardware requirements and excellent security performance. Based on OpenStack, an open-source cloud computing platform, we build a platform for the end-users of antenna simulation in universities, pint-sized enterprises and scientific research institutions. It can allocate computing resources flexibly and satisfy consumers according to their requirements such as on-demand use, running smoothly.
