> There is no relay in Silkroad. What? The figure in section 4.1 (Silkroad Model) of draft-liumin-v6ops-silkroad-01.txt clearly shows a "SAR'" in the path between a regular IPv6 node and a node using the silkroad scheme. This is exactly the same role as a Teredo relay, or a 6to4 relay. -- Christian Huitema
