High-Speed Data Flow in the Operating Room with Software-Defined Networking<\/strong><\/p>\n\n\n\n

The Institute of Embedded Systems (InES), High Performance Multimedia Group has taken a leap forward in high-speed data transfer in surgical environments. We have developed a high-speed (25Gbps) network switch built on an ARM System-on-Chip (SoC), achieving up to 25 Gbit\/s switching performance without relying on dedicated switching hardware.<\/p>\n\n\n

This innovative solution is the result of a collaborative project with the University Clinic Balgrist, focusing on decentralized data capture and distribution. The solution is built on ZHAW’s Jetson Orin NX Modular Vision System,<\/a> equipped with an Intel E810 25Gbps PCIe Network Interface Card. The need for a modular high performance software switching solution is due to the fact that on the host system, various different tunnelling protocols are running in parallel<\/p>\n\n\n\n

The Power of Open Source: Open vSwitch and DPDK<\/strong><\/a><\/p>\n\n\n\n

The solution is built on the two open-source frameworks Open vSwitch (OvS) and Data Plane Development Kit (DPDK).<\/p>\n\n\n\n

OvS is a production-ready, multi-layer virtual switch known for its programmatic extension capabilities, enabling extensive network automation. However, a key limitation of native OvS is its dependence on the Linux kernel network stack, which is a bottleneck in high-speed applications.<\/p>\n\n\n\n

This is where DPDK steps in. This open-source software project provides libraries that accelerate packet processing by entirely bypassing the kernel and operating purely in the Linux user space.<\/p>\n\n\n

By combining Open vSwitch and DPDK on the Orin NX modular vision platform, we’ve created a highly adaptable, high-speed multi-layer switch that runs within the Linux user space, eliminating the need for dedicated hardware. The system reaches impressive 25 Gbps port-to-port switching and 10 Gbps port to host system switching.<\/p>\n\n\n\n

Revolutionizing Surgical Research and Learning<\/strong><\/p>\n\n\n\n

This innovative network switch will be deployed within the OR-X<\/a> of Balgrist, cutting-edge research and learning centre for translational surgery. Together with the existing DGX high performance workstation, it will empower the research teams of Balgrist to collect and stream high-speed data in real-time, paving the way for advancements in surgical techniques and research.<\/p>\n\n\n
