| Abstract(in English) | In recent years, many new services that process data at remote base have appeared. In such new services, it is important to reduce application-level delays, i.e. end-to-end delays experienced by the users, in order to improve the users' quality of experience. The concept of Multi-access Edge Computing (MEC) is expected that the delays are reduced. However, the processing capability of edge servers is generally lower than that of data centers. Service functions capable of effectively reducing application-level delays should be deployed on edge servers. For future deployment of MEC, it is therefore necessary to clarify application-level delays and its occurrence factors in a MEC environment, and to investigate how to make the application-level delay lower by reallocations of the functions. In this paper, we construct an MEC environment using OpenStack and Amazon Web Service, then operate a video live streaming service with real-time processing. Results of our measurement and analysis of the application-level delay shows that, for low-latency video live streaming, it is naturally important that the average of propagation delays is small, but it is also important to suppress the jitter caused by the network side. Based on this findings, we devise and implement a simple service reallocation method for low-latency video live streaming. Our experimental results show the application-level delay is kept under 400~ms and video quality is comfortable by the method. |
