Abstract

This paper proposed an active fault-tolerant priority migration decision model for virtual machines based on attentional spatio-temporal convolution and A2C(AST-A2C). This method improved reliability and adapted to volatile workloads in resource-constrained edge cloud computing environments. Firstly, it used a long short-term memory network(LSTM) with an attention mechanism to extract the temporal features in each host. It combined temporal features and interaction information between multiple hosts to build graph networks. Then it used graph attention network(GAT) to extract association information between different hosts in the network, and the association information would be used to encode the fault information of hosts. Next, it designed the A2C module to dynamically build models and continuously generate improved decisions, this module could combine fault code information and scheduling decision information for priority migration decision. It constructed adaptive loss functions to optimize scheduling decisions to meet different user QoS requirements and application settings. Experimental results show that the proposed model outperforms the state-of-the-art baseline in terms of fault detection, energy consumption, and delay sensitivity. It is ideal for improving the reliability of edge cloud computing.
