However, the currently used tunnelling protocol, i.e., GTP, might not be the most appropriate choice for the envisioned scenarios, given its unawareness of the underlay network. In this paper, we analyse the use of an alternative tunnelling protocol to transport user data, namely, Segment Routing IPv6 (SRv6). More specifically, we discuss its qualitative advantages, present a prototype implementation, and carry out an experimental comparison vs. GTP, confirming that it constitutes a valid alternative as tunnelling protocol6eng© 2020 IEEE.Protocols5G mobile communicationRoutingNetwork slicingTunnelingKernelEncapsulationconference paperTelecomunicacioneshttps://doi.org/10.1109/CAMAD50429.2020.9209260open access162020 IEEE 25th International Workshop on Computer Aided Modeling and Design of Communication Links and Networks (CAMAD), 14-16 September 2020 (Virtual Conference)CC/0000030862
