A Distributed Fog Computing Architecture Supporting Multiple Migrating Mode

Fog computing is a new computing mode. As a derivative of cloud computing, fog computing can solve the problems of high latency, overloaded center server and overloaded bandwidth of network. There are many kinds of existing fog computing architectures, which lacks flexibility in handling of tasks and interaction of networks. In this paper, based on the advantages and problems of the existing fog computing architectures, we propose a distributed fog computing architecture that supports multiple migrating mode, which include center-edge, edge-edge migrating. The main research contents and contributions of this paper are as follows: (1) Propose a distributed architecture that contains user management node, network management node and service node on center and edge network. (2) Design a scalable distributed computing node model in Edge Network. (3) Carry out a user registration method based on distributed storage. (4) Design a service migration model based on the load of Network, which included the center-edge and edge-edge migrating support.
