the real question is what percentage of public Internet routers 1) does have MPLS hardware forwarding support 2) does have IPv6-SR hardware forwarding support. and 3) what is the pricetag for the hardware upgrade. furthermore 4) what is the cost increase for future hardware to support a redundant dataplane which does more or less the same thing than exisiting hardware. | Also, introducing SRH processing in existing v6 networks is not a | major change (nothing compared to a migration to a different | dataplane). since most v6 hardware implementations i am familiar with, do not have support for parsing SRH processing, what you are suggesting here *is* a migration to a different dataplane. (and i am pretty sure you did not want to tell the list that introducing support for dataplane #4 on the internet is free of charge for all your employers' v6 products). /hannes _______________________________________________ spring mailing list [email protected] https://www.ietf.org/mailman/listinfo/spring
