... The deployment of 5G networks mainly includes two parts: the radio access network (RAN) and the core network (Zhu and Xiang, 2016;Wang et al., 2017). Currently, 5G network deployment methods can be roughly divided into five categories: enterprise self-built, licensed spectrum, shared base station, unique user plane management (UPF)/MEC, and network slicing (Ahmad, 2019;Li et al., 2021). In order to meet the needs of communication networks and reduce construction costs, different deployment and construction plans are proposed according to the actual situation. ...

... However, the deployment used for experiments does not include the WAN (i.e., inter-DC) network scenario [47] or does not reproduce realistic cloud and network deployments [48][49] since making use of emulation platforms at data plane level, e.g., Mininet. On the other hand, some experimental initiatives have tackled the deployment and the management of vertical services that may span multiple provider domains [50] [51]. However, in these works, neither latency-awareness features nor end-to-end monitoring to guarantee reliability are addressed for established service chains. ...
