Hello, draft-pfeifer-6man-exthdr-res-01 proposes an idea to reserve a small area of protocol numbers in advance. IPv6 extension headers (or protocols) which use one of these numbers are forced to structure the extension header to be formatted as outlined in pre-draft-ietf-6man [1]. This allows operating systems to code these numbers in advance in the stack.
This enables two opportunities 1) future standardized extension headers can be deployed without being dropped by older routers where the extension header isn't known 2) vendors can test experimental extension headers in their networks Hagen [1] http://tools.ietf.org/html/draft-ietf-6man-exthdr-04 -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
