(usagi-users 03304) Re: Where should I begin to make use of the hop-by-hop option?

Dear Masahide,

Thanks very much for your suggestions.  I will take a
look at the file you suggested.

Regarding the "changes" I want to make, it is
basically an algorithm to enhance the routing table
lookup performance with mobile IPv6.  When a lot of
mobile nodes are located in the foreign routes, the
routing table will be very "flat" (i.e., the router
has to lookup the entire 128-bit address for each
packet addressed to those mobile nodes). I want to
implement the algorithm I have in mind to reduce the
"flatness" of the table.

Is there any similar algorithm out there?  Actually,
do you know how the routing table handles the routing
for foreign mobile nodes?

Regards,

Patrick
