基于X86通用硬件平台的高性能5G核心网UPF实现

摘要：5G网络应用对核心网用户面网元（UPF）性能提出了更高要求。本文研究了基于X86通用硬件平台的高性能5G核心网UPF方案，通过利用第三代至强处理器和800系列网络适配器的内置硬件特性，不需要额外的专用硬件加速器，使UPF整机转发吞吐量可达462 Gbit/s。该方案对动态设备个性化（DDP）技术进行了深度开发，实现了UPF整机转发吞吐量比前代平台提升334.8%、转发延迟降低50.7%的性能突破，并可以有效节省系统总体成本。

Abstract: High-performance 5GC user plane function (UPF) is critical to meet the needs of 5G network applications. A high-performance 5GC UPF solution is proposed in this paper, based on the hardware features of the 3^rd Gen Intel Xeon Scalable processors and Ethernet 800 Series Network Adapters, without any additional hardware acceleration. Test results indicate that the forwarding performance can reach up to 462 Gbit/s. This UPF solution achieves 334.8% throughput improvement and 50.7% latency reduction than the previous generation hardware platform, based on the deep development of DDP technology. It can also cut down system total cost.
