Hi, I really
appreciate your previous replies.
I got two more questions on
centralized multicast.
1. about multicast tree
construction
what is the
tree construction method from RP to receivers? Is it Reverse
Path Forwading
?
and If I will construct tree from
RP through intermediate several nodes to Receivers as I want to, How and
what can I modify ?
2. about RP
reset
I modify tcl example.
After setting up a RP as below,
I want to change the RP to another one.
How can I do that in same tcl
script?
--------------------------------------- if {$mrthandle !=
""} { $ns at 0.5 "$mrthandle set_c_rp [list
$n1]" } ----------------------------------------
When I inserted something as below.
ns starts RP from $n6, not $n1.
I want to simulate first RP $n1 and
second RP $n2.
I saw the nam siwtch the
simulation from RPT to SPT by using switch-tree procedure in example
file.
How can I do that?
----------------------------------------- if {$mrthandle != ""}
{ $ns at 0.90 "$mrthandle set_c_rp [list $n6]" $ns at 0.90
"$mrthandle compute-mroutes"
} ------------------------------------------
I am looking forward to your
reply.
Thanks a
lot. |
