I
suggest that as a general rule the COSMOS DC should avoid using IP addresses
whenever possible. For example, the COSMOS DC should replace the IP addresses
in the muse WSDM EPRs with hostnames:
INFO: [ID = 'ResourceInitialized'] The resource at
'/org.eclipse.cosmos.dc.runtime.osgi.OSGiRuntimeHost' has been initialized.
Bound<wsa:EndpointReference
xmlns:wsa="http://www.w3.org/2005/08/addressing">
<wsa:Address>http://192.168.0.103:8080/cosmos/services/org.eclipse.cosmos.dc.runtime.osgi.OSGiRuntimeHost</wsa:Address>
<wsa:ReferenceParameters>
<muse-wsa:ResourceId
xmlns:muse-wsa="http://ws.apache.org/muse/addressing">RuntimeIdentifierValue</muse-wsa:ResourceId>
</wsa:ReferenceParameters>
</wsa:EndpointReference>
Hostnames are more “stable” than
IP addresses. This is important because the EPRs may be registered in various
components across the network (like the Brokers) and the IP address may change
after a machine reboot. Also IPv6 support introduces multiple addresses and formats
for the same physical machine, potentially causing a problem maintaining unique
EPRs in the registries.

compliance for COSMOS DC
Jimmy,
It would be good if we can
get specific enough to be able to understand the
configurations that we would need to test. I assume that there is no
requirement to support a v6-only network so I would expect most things to just
work by encapsulating v4 traffic.

Don,
Even though I probably will not be on, can
we please cover this tomorrow (even if briefly)? If I cannot make it, Mr.
Muldoon will represent me. To ++ what you say, If we can, I would
STRONGLY prefer the DC to stay independent of this issue. The IP v6
compliance has extensive legal implications at our end.
Thanks,
Jimmy Mohsin

I hope that we can avoid storing
or processing IP addresses as such so we can remain relatively independent of
this issue. That said, if we need to support configurations
that employ IP v6, we will need to test them.
Perhaps we could discuss this on
tomorrow's architecture call.

All,
Do you see any IP v6 compliance issues for the COSMOS DC?
Thanks,
