IEEE P1935 Edge/Fog Manageability and Orchestration: Standard and Usage Example

With the innovation of mobile applications and the arrival of the fifth generation of telecommunication, edge computing has become a popular scheme due to its geographical proximity to end users; thus, the overall architecture has the advantage of lower latency and higher user experience. However, because of the physical limitation, management and orchestration in the edge system are necessary to maintain operations, standard functionalities and application lifecycle. Accordingly, the IEEE P1935 working group introduced a standardized, orchestration-wise design to simplify the process and offer better system performance and user experience. In this work, we first give an overview of the three-level Edge/Fog architecture in the P1935 standard and briefly show the components in each level. Moreover, we describe the mechanisms for managing and orchestrating resources and applications. Last but not least, we implement an actual testbed following the standard. To show that the P1935 standard can benefit the Edge/Fog systems, we deploy an edge-based live-streaming service and a real-time transcoding mechanism on the testbed. The evaluation results show that the P1935-aligned system performs well regarding the overall Quality of Experience (QoE).
