5G-Mantra: Multi-Access Network Testbed for Research on ATSSS
Abstract
The steady global deployment of 5G has enabled advancements in quality of service and introduced new standards that allow for better utilization of heterogeneous access networks. While existing functionality such as WiFi Offloading has enabled data sessions over alternative access networks to 3GPP RAN, 5G introduces ATSSS, which enables true link aggregation for the first time. Existing solutions fail to allow researchers to conduct end to end experimentation with ATSSS and lack the capability to support core network analytics. This thesis introduces 5G-MANTRA, a testbed that unifies widely used open source core network solutions and implements a standards-compliant MPTCP proxy for enabling ATSSS. We compare our testbed to existing solutions in addition to validating its ability to measure ATSSS scenarios in both lab and real world environments. We demonstrate that our solution answers the shortcomings of existing work and produces crucial data for measuring heterogeneous network performance.
