One area where it would perhaps make a difference for SDN is in the case of merging two SDN controlled regions. Global identifiers (for anything) that overlap between the two SDN regions that must then be merged/deconflicted would be tricky to deal with.

The SDN (centralized) approach makes allocation of global IDs easier. However, Xiaohu asked a data plane question. Local IDs are much easier for the data plane. BTW, I am not in favor of centralizing everything. Kireeti _______________________________________________ nvo3 mailing list [email protected] https://www.ietf.org/mailman/listinfo/nvo3
