One thing I didn't see mentioned here is probably relevant. Encap/decap has a potential to be much more difficult if fragmentation would be incurred (especially outer header fragmentation); I have hard time seeing how you could even implement a line-speed decapsulator that would reassemble fragments as required by Full Standard IP RFCs. The same problem could happen if you translated v4->v6 as well (i.e., payload size shrinkage). See draft-touch-intarea-tunnels-00 and rfc4459. As a result for encap/decap schemes I specifically want to see how they 100% avoid fragmentation, or describe how they deal with it. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
