Systems, devices, and methods are disclosed for enabling the reconfiguration of services supported by a network of devices. Such reconfiguration can be realized dynamically and in real time without compromising the security of the overall system from external threats or internal malfunctions. These systems, devices and methods may provide a first functional stack supporting a previous version of a specific service and the provisioning of a second functional stack dynamically and in real-time that supports an updated version of the specific service. In addition, an administration function may be included in the embodiment such that the administration function manages and controls the functional stacks and network operations. Using these mechanisms, an existing service can be changed dynamically or a new service can be added dynamically in a secure manner without interruption of other existing services.
