Implementing Application-Specific Edge Computing Network Architecture for 5G Networks

摘要

In this paper, we present an application-specificMulti-Access Edge Computing (MEC) network architecture byleveraging the Control and User Plane Separation (CUPS) inmobile core networks to ooad data trac from dierentapplications to dierent edge servers for application-specificprocessing. We first apply deep-learning to classify trac intoapplication-based EPS bearers. Then, to physically isolate EPSbearers of the same PDN connection, we slice the PDN gateway(P-GW) into multiple physically distributed P-GW slices sothat its attached edge server can be distributedly deployed ondemand.We prototype the proposed application-specific MECnetwork architecture using modified OpenAirInterface LTE/5Gsoftware. Our modification is 3GPP-compatible so that it couldbe acceptable by mobile network operators. It is applicable inboth non-standalone (NSA) and standalone (SA) 5G networks.
