Re: the COMPRESSION discussion




Just to be clear, I _personally_ am indifferent about compression.
As co-chair, I'm very religious about following the standards process.
Before we can move forward there MUST be rough consensus within the WG
on how to proceed.  Right now this just is not present.  Sigh.

The items that the IPsec WG needs to sort out are:

1) Is compression "must implement" or "optional to implement" or
	"outside our scope" ?

If its inside our scope, then these next items also need to
be sorted out:


2) What compression mechanism (not algorithm, but how to implement 
	and at what processing layer) should be used ?
3) How to ensure that the compression mechanism can support arbitrary
	compression algorithms so that a new gee-whiz compression
	algorithm can be added modularly without changing everything.

Reasonable steps towards progress might include:
	- Various people writing up various approaches as I-Ds and
	  presenting these in Memphis (warning: time is short)
	- Discussing specifics on the IPsec list, noting which items
	  are most important.
	- A clear agreement on the scope of the problem that should
	  be addressed.
	- Deciding whether compression is just an ESP issue or 
	  whether it might be good to have a more generalised scheme 
	  for IP-layer compression of any IP packet (not just those 
	  packets with IPsec)
