Re: [savi] Summary Document on SAVI Design Decisions So Far

Frank,

the scenario here is that the SAVI device is implemented on a switch  
that connects the router with the packet recipient.  Therefore, the  
SAVI device, when receiving the packet from the router, believes that  
the router is spoofing the IP source address of the sending host.

You are right; this should be clarified in the text.
