OpenAirInterface Traffic Generator (OTG): A Realistic Traffic Generation Tool for Emerging Application Scenarios

Abstract

Traffic generation represents one of the main challenge in modeling and simulating the application and network load. In this work, we present a tool, called OpenAirInterface Traffic Generator (OTG), for the generation of realistic application traffic that can be used for testing and evaluating the performance of emerging networking architectures. In addition to the traffic of conventional applications, OTG is capable of accurately emulating the traffic of new application scenarios such as online gaming and machine-type communication. To highlight the capability and new features of the tool, the one-way delay of OpenArena online gaming application in the presence of the background traffic is analyzed over the LTE network using OpenAirInterface emulation platform.
