Abstract
A communication system with a control circuit is disclosed. The circuit includes an operating system for exchanging messages and user software, and a device for exchanging software. For a software component to be exchanged in a few milliseconds, a newly loaded software component, corresponding to a successor component, obtains states and messages from a service port of a stopped software component that is to be replaced, corresponding to a predecessor component. The successor component is restarted with the transferred states and messages.
