2. March 6 th, 2009 OGF 25 Unicore 6 and IPv6 readiness 2 at a glance UNICORE is a fully integrated grid middleware solution which allows creating, submitting and monitoring of computing jobs. It mainly consists of a Gateway, a Network Job Supervisor (NJS), a UNICORE User Database (UUDB), an Incarnation Database (IDB), and a Target System Interface (TSI).

6. March 6 th, 2009 OGF 25 Unicore 6 and IPv6 readiness 6 and IPv6 UNICORE 6 is implemented in Java and concerning IP connectivity issues relies on IPv6 support in Java and libraries The program code itself does not deal with IP addresses directly. Those will be retrieved by name resolution only. Since IPv6 support generally available in Java, there should be minor modifications be needed only. Some 3 rd party libraries had issues a long time ago No positive or negative confirmation Might be solved by now But needs verification in an IPv6 testbed Same applies to UNICORE code itself Hasnt been tested in IPv6 environment yet Testers with an access to IPv6 testbed are welcome

7. March 6 th, 2009 OGF 25 Unicore 6 and IPv6 readiness 7 IPv6 readiness summary Until today no requests for IPv6 compliant UNICORE software has been addressed. Only small modifications will be necessary. Therefore we assume, that UNICORE 6 will be IPv6 ready as soon as requirement for this will come up.
