Efficient Large-Scale Multiple Migration Planning and Scheduling in SDN-enabled Edge Computing (2111.08936v1)

Abstract: The containerized services allocated in the mobile edge clouds bring up the opportunity for large-scale and real-time applications to have low latency responses. Meanwhile, live container migration is introduced to support dynamic resource management and users' mobility. However, with the expansion of network topology scale and increasing migration requests, the current multiple migration planning and scheduling algorithms of cloud data centers can not suit large-scale scenarios in edge computing. The user mobility-induced live migrations in edge computing require near real-time level scheduling. Therefore, in this paper, through the Software-Defined Networking (SDN) controller, the resource competitions among live migrations are modeled as a dynamic resource dependency graph. We propose an iterative Maximal Independent Set (MIS)-based multiple migration planning and scheduling algorithm. Using real-world mobility traces of taxis and telecom base station coordinates, the evaluation results indicate that our solution can efficiently schedule multiple live container migrations in large-scale edge computing environments. It improves the processing time by 3000 times compared with the state-of-the-art migration planning algorithm in clouds while providing guaranteed migration performance for time-critical migrations.
