> Why not just use IP to MAC calls? Or use the MAC as the GUID? We do use standard OS services to map the IP addresses (that were encoded in the GID) to MACs. GIDs encode IP addresses rather than MACs to enable users to use the node names that they are used to. Specifically, we will feed in all IP addresses that were assigned to the Ethernet interface to the corresponding port GID table. This will also enable routing in the future.
The only exception is IPv6 link-local addresses, which already encodes the MAC. In this case, a simple algorithmic operation extracts the MAC without requiring ARP, etc. > Do the GIDs follow the IB GID format? Yes. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
