I've opened a corresponding issue (https://issues.apache.org/jira/browse/FLINK-1275). The network layer is going through a set of big changes at the moment. I think it makes sense to wait for them to be finished/merged, before working on this. @Viktor: If you want to work on this, feel free to comment on the JIRA issue and we can discuss at which points you would have to extend the system. – Ufuk
