[Mini-NDN] [Nfd-dev] Doubts regarding face creation

[Lan Wang (lanwang)]

Ashlesh,

I don't see how nfdc register is going to help if NLSR does not support parallel links (I may have misunderstood something).  But since Navdeep has joined the mini-ndn mailing list, let's move the discussion there.

Hi

So this is happening because NLSR does not support parallel links as of now. It will simply ignore the second neighbor in the configuration file. I have filed a feature request:
http://redmine.named-data.net/issues/3097
But it will not be in the near future as it requires some design and implementation work.

Right now you will have to do that manually. If your topology is fixed you can do it within the code
so you don't have to do it manually every time the topology comes up.

Example: In bin/minindn you can do something like net.hosts['g1'].cmd("nfdc register ....")

Subject: [Nfd-dev] Doubts regarding face creation

Hello All,



I am working on minindn. While creating the topology I am using the following configuration file:
[nodes]
h1: _
h2: _
h3: _
h4: _
g1: _
[links]
h1:g1 delay=10ms bw=10
h2:g1 delay=5ms bw=1
h2:g1 delay=0ms bw=2
h3:g1 delay=0ms bw=1
h4:g1 delay=0ms bw=3





As per my understanding, between h2 and g1 there should be 2 faces created but I am finding only one face created for this, and the other connection I have to make explicitly. Please confirm if this is expected behavior,  if I am doing anything wrong  or my understanding is wrong.



For g1, faces are :
Faces:
  faceid=1 remote=internal:// local=internal:// counters={in={0i 81d 0B} out={132i 0d 0B}} local persistent point-to-point
  faceid=254 remote=contentstore:// local=contentstore:// counters={in={0i 0d 0B} out={0i 0d 0B}} local persistent point-to-point
  faceid=255 remote=null:// local=null:// counters={in={0i 0d 0B} out={0i 0d 0B}} local persistent point-to-point
  faceid=256 remote=fd://18 local=unix:///run/g1.sock counters={in={92i 27d 36942B} out={27i 43d 45212B}} local on-demand point-to-point
  faceid=257 remote=fd://20 local=unix:///run/g1.sock counters={in={1022i 223d 208468B} out={912i 288d 231943B}} local on-demand point-to-point
  faceid=258 remote=udp4://1.0.0.1:6363 local=udp4://0.0.0.0:6363 counters={in={766i 74d 106769B} out={784i 89d 115716B}} non-local persistent point-to-point
  faceid=259 remote=udp4://1.0.0.5:6363 local=udp4://0.0.0.0:6363 counters={in={767i 65d 102476B} out={779i 89d 115339B}} non-local persistent point-to-point
  faceid=260 remote=udp4://1.0.0.13:6363 local=udp4://0.0.0.0:6363 counters={in={767i 67d 103289B} out={779i 89d 115605B}} non-local persistent point-to-point
  faceid=261 remote=udp4://1.0.0.17:6363 local=udp4://0.0.0.0:6363 counters={in={768i 68d 104006B} out={782i 89d 115879B}} non-local persistent point-to-point
  faceid=265 remote=udp4://1.0.0.9:6363 local=udp4://0.0.0.0:6363 counters={in={0i 0d 0B} out={0i 0d 0B}} non-local persistent point-to-point
  faceid=266 remote=fd://25 local=unix:///run/g1.sock counters={in={3i 0d 137B} out={0i 2d 903B}} local on-demand point-to-point



Highlighted one I created explicitly using nfdc register.
Also, please explain the significance of the counters [counters={in={0i 0d 0B} out={0i 0d 0B}}]







Best Regards,
Navdeep Uniyal
