This paper addresses QoS routing in an integrated network architecture based on the software-defined networking and edge computing technologies. Our study leverages the bene- fits of edge computing to differentiate data flows of different ser- vice types, as well as the programmable features of the software- defined networking to manipulate the forwarding behavior on data flows. Joint QoS-specific factors of latency and packet loss are used to design a novel path selection method for data delivery in such an integrated network. Simulation under heavy traffic patterns shows that our method performs better with lower latency and packet loss rate simultaneously as compared with typical OSPF and some greedy-like routing methods.
