i-D: IPv6 Extension Headers Reserved Space

[Hagen Paul Pfeifer <[e-mail]>]

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
