AB  - Poor Internet performance currently underminesthe efficiency of hyper-responsive mobile apps such as augmentedreality clients and online games, which require low-latency accessto real-time backend services. While edge-assisted execution, i.e.moving entire services to the edge of an access network, helpseliminate part of the communication overhead involved, this doesnot scale to the number of users that share an edge infrastructure.This is due to a mismatch between the scarce availability ofresources in access networks and the aggregate demand forcomputational power from client applications.Instead, this paper proposes a hybrid edge-assisted deploymentmodel in which only part of a service executes on LTE edgeservers. We provide insights about the conditions that must holdfor such a model to be effective by investigating in simulationdifferent deployment and application scenarios. In particular,we show that using LTE edge servers with modest capabilities,performance can improve significantly as long as at most 50%of client requests are processed at the edge. Moreover, we arguethat edge servers should be installed at the core of a mobilenetwork, rather than the mobile base station: the difference inperformance is negligible, whereas the latter choice entails highdeployment costs. Finally, we verify that, for the proposed model,the impact of user mobility on TCP performance is low.
