Fog Server Deployment Method Based on Host Location and Traffic Pattern in Fog Computing Environment

摘要

The present invention provides a fog server based on a host location and traffic pattern in a fog computing environment in which a logical flow is generated to obtain a current bandwidth usage of a link between a fog device and a core network and the fog server is arranged based on the link bandwidth usage. Method, which is represented by a straight line from the data source to the client, in the direction (Src, Dst), bandwidth usage before and after going through the server ( Generating a logical flow ( f ) having computing resource size information necessary for processing; using the generated logical flow ( f ), a link between the fog device and the core network ( Determining a current (Rank) order of candidate fog devices in which the fog server can be placed based on the obtained link bandwidth usage between the fog device and the core network; based on the obtained Rank And deploying a fog server based on a ratio of traffic occurring in the core network and traffic occurring in a local area.
