Abstract
Result of this work is a principled mechanism for relocating a running process to another executing device during runtime while preserving its execution state. This covers Re-Deployment of the executable code and seamless Live-Migration best categorized as Parallel Process Migration. The presented mechanism is actually applicable under any circumstances where desired. But the target application environment that was in mind while developing where dynamic and flexible networks that are re-shaping themselves constantly during runtime; especially Organic 6G Infrastructures. The declared goal is to move a process between devices while it is executed and that with at least as possible timing issues caused by the relocation itself, like a temporary unavailability of the service. The ultimate feature is not to have redundancy or any kind of backup execution. Instead, while actively running and producing system, it occurs repeatedly that a permanently running program is required to run on a different physical location than it currently is. Beforehand, it is not known when or where a process is to be relocated to, which depends on runtime circumstances. It happens randomly that the running system, caused by the infrastructure or by utilizing applications, requires a process to move to a different device while having a seamless availability of the service, without outage and preferably equal access timings.
