Integrating Real-Environment 4G and 5G Mobile Data Patterns into Network Simulations for Delay Analysis

Abstract

This article presents a simulation testbed for analyzing a mobile transport network using open-source networking tools and protocols. The topology was designed according to the 5G transport network architecture, with Segment Routing for IPv6 (SRv6) technology and The Fast Data Project Vector Packet Processor (FD.io VPP) utilized for packet processing. The Trex traffic generator was used to simulate data transmission, and the Docker platform enabled centralized access and management of the topology. Real data patterns collected from one cell site was inserted into the created topology to create output for future research. The created testbed provides a valuable tool for analyzing the mobile transport network's performance and future optimizing based on needs of network slices.
