ISPs do exist for customers, not customers do exist to feed ISPs in the most convenient way for the ISPs. Some folks seem to forget that, looking at all the discussion trying to ignore the demand for real multihoming (and that includes TE and network-wide routing policy implementation, neither being delivered by things like shim6).
I think you are contradicting yourself here. Shim6 does give the end-
s/does/may ? ;)
user TE capability. It does not give the ISP the possibility to ignore it, as they could today.
Shim6 is work in progress and may be used as an argument to adjust adress-assignment policies sometime in the future. If we want ipv6 deployed today we have to provide a mechanism to support requirements about redundancy and independence from individual providers.
I am not sure what you mean with "network-wide routing policy implementation"....
I guess this relates to supporting infrastructure necessary for shim6 to support or replace current ipv4 technology like load-balancing, filtering etc. If standards are defined today and everyone agree to implement them asap it will still take years before such products are available and a commercially viable alternative. Shim6 has a potential to provide improved "granularity" in traffic management (individual path-selection for each source-destination HBA-pair) but that is irrelevant until the technology is actually there. Bottom line: it's fine to develop technology for the future, but operational procedures and policies must be supported by current technology. //per -- Per Heldal heldal@eml.cc
