Development of an ultralow-latency communication system using shared internet access: promoting the implementation of telemedicine

Abstract

Telemedicine is becoming increasingly important to address the shortage of gastrointestinal surgeons and disparities in domestic and international treatment outcomes for patients with colorectal cancer. The development of a low-latency communication system using existing communication infrastructure (shared internet access: SIA) is necessary to promote the use of telemedicine. The aim of this study was to develop a low-latency communication system using SIA. We conducted an experiment between Sapporo and Tokyo using an ultralow-latency communication system for remote medical education (TELEPRO®). The latency was measured using 2000 annotations from a monitor in Sapporo, which confirmed a median latency of 27.5 ms. A low-latency communication system based on SIA with latency lower than the maximum allowable latency for telemedicine was developed successfully.

The entire system is based on 2 remote locations connected to a wide area network (WAN) through the internet via the TELEPRO® server. Room 1: Precision Tower 5820®. The CPU used in the experiment was Intel® Xeon® W-2245, the GPU was NVIDIA Quadro RTX 4000, and the memory was 64 GB. Room 2: HP ENVY Laptop 15-ep0xxx. The CPU used in the experiment was Intel® Core™ i7-10750H, the GPU was NVIDIA GeForce GTX 1660, and the memory was 16 GB. The refresh rate of the monitor was 60 Hz
