draft-ietf-ipatm-encaps-00.txt

Our implementation of RFC 1577 uses only LLC/SNAP encapsulation for
several reasons:

	1) Sloth.  We need to interoperate with other implementations,
	and LLC/SNAP encapsulation is always available.  We also didn't want
	to implement more than was needed in a first release.

	2) With NULL encapsulation, one needs some mechanism to distinquish
	ARP frames from IP frames, and we can't do this when connections are
	established because the draft signaling standard doesn't provide a
	mechanism.  Using LLC/SNAP encapsulation allowed this
	to be done in a way that fits in well with our existing IP
	implementation and was easy to implement.
