i am trying to understand how the network_region is used.<br>
Here is the text from nfd.conf.sample:<br>
<br>
; Declare network region names<br>
; These are used for mobility support. An Interest carrying a Link object is<br>
; assumed to have reached the producer region if any delegation name in the<br>
; Link object is a prefix of any region name.<br>
network_region<br>
{<br>
; /example/region1<br>
; /example/region2<br>
}<br>
<br>
<br>
As a specific example, lets take the two nodes on the campus of UCLA: REMAP and UCLA.<br>
The current default prefix for UCLA is: /ndn/edu/ucla<br>
The current default prefix for REMAP is: /ndn/edu/ucla/remap<br>
<br>
Should they both declare a network region of /ndn/edu/ucla<br>
or should REMAP be more specific and declare /ndn/edu/ucla/remap?<br>
<br>
If they both declare a network region of /ndn/edu/ucla does that imply that<br>
there MUST be a link between the two nodes?<br>
<br>
Thanks,<br>
