Due to the centralized nature of service platforms, resource-demanding services suffer from long delays when a user is accessing them when roaming. With the globalization of our society, such data intensive services are enabled at the high cost required by provisioning high-speed inter-domain connections. Delivering those services from the local, visited domain (instead of the home domain), does not only overcome the aforementioned limitations, but also opens new possibilities for service delivery. An operator could expand its service delivery reach to a global coverage, enjoying all the benefits of such a move. We propose Service Program Mobility as a novel paradigm for global service provisioning. Our system architecture realizes dynamic service component migration across operator domains and platforms to offer the same experience to roaming users as they would have in the home network. %K Mobile Services %K Service Mobility %K Service Delivery Platform %K Service Roaming %K Service Migration %K Mobile CDN %K In-Network Services %K Network Virtualization %U http://ojs.academypublisher.com/index.php/jcm/article/view/6234
