foil1------------------------
How many addresses?

1.Duplicate
  MAC stations exist

2.VLAN-challenged
  bridges in
  backbone 
  (giant-enabled)

3.Stations connect
  to 2 different
  switches

Consensus: Exterior addressing is important.
foil2--------------------------
How long can the tag be?
1.Next 'interesting' length after
  1518 bytes occurs when length Byte=0x5FF
  ...  tag<= 35 bytes (Plenty)
       ---------
Ethertype vs LLC ?
1.Ethertype allows cut-through
2.Ethertype is smaller
3.Computing/inserting length is hard
    ==>  Ethertype
        ------------------
	FDDI & 802.5?
Supporting translational bridges requires FDDI to use SNAP
Encoding.  802.5, no conclusion
foil3----------------------------------------------
GOALS:
1.4-byte alignment reg'd
  8-byte alignment desired
2.Minimal Frame expansion
3.Preserve original frame
4.Only add data in one place

                 (12 bit minimum VID)
(CRC, normalization, *if used* !!!)

Observations:
	Tag must be media-dependent.  
The tag goes on top of the MAC layer, not instead of it.

1.FDDI Version (SNAP)
2.802.5 (SNAP or LLC)
3.Entry-level ethernet Encapsulation !short-form!
	-target the common configurations without the
	 full overhead
4.What goes in the flags
	-may drive a need for an ethertype range
5.What fields are generated vs. checked...
