Follow-Me Cloud: An OpenFlow-Based Implementation

Services are increasingly provided by cloud computing systems. Such services are often accessed while on the move. If the distance between the user and the service is getting large, quality-of-experience, in particular for interactive services, deteriorates. To counter this, the provisioning location of the service should be as close to the user as possible. This paper describes the concept of follow-me cloud, according to which services are migrating in unison with the user's movements. The key components required for such integrated user mobility/service mobility management are introduced and mappings to an OpenFlow-based implementation are described.
