Abstract: A further communication bridge 14 is integrated into a running data processing system 210, which comprises a communication client 10 running a first operating system 16 having no own communication stack and at least a first communication bridge 12 running a second operating system 18 having an own communication stack 20. The first communication bridge 12 acts as a master communication bridge 26 and the further communication bridge 14 runs a third operating system 19 having an own communication stack 22. The further communication bridge 14 announces itself as a slave communication bridge 28 to the master communication bridge 26 at an announcement time and the master communication bridge 26 executes a quiesce process on a network adapter 68 and on an API 62 of the communication client 10 when there are no data packets in a queue with a sending time earlier than the announcement time. The master communication bridge 26 extracts the state of its communication stack 20, sends it to the further communication bridge 14 and resumes the network adapter 68 and the API 62.

Abstract: Integrating a further communication bridge into a running data processing system. The data processing system includes a communication client running a first operating system having no own communication stack and at least a first communication bridge running a second operating system having an own communication stack. The first communication bridge is configured as a master communication bridge. The further communication bridge announces itself as a slave communication bridge at an announcement time. The master communication bridge executes a quiesce process on the network adapter and on the API of the communication client when there are no data packets in the queue with a sending time earlier than the announcement time. The master communication bridge extracts the state of its communication stack and sends it to the further communication bridge. The master communication bridge resumes the network adapter and the API.
