People, The topology files in github are a bit of a mess and I have been fixing them up all day. If you are not dynamically downloading them you may want to pull and update. John.
More issues. I am assuming the A-GOLE diagram is intended to be somewhat accurate and therefore... 1. Startap or Startlight - how is it suppose to be named? 2. Northernlight or nordu.net? 3. Pioneer and Geant are not connected in topology but are in the diagram. 4. Geant thinks it is connected to Netherlight in topology but Netherlight disagrees. The diagram disagrees as well. Very hard for path computation to get anywhere with all the current issues. John On 2013-09-24, at 9:32 PM, John MacAuley <john.macauley@surfnet.nl> wrote:

Gloriad - not on the diagram but connected to krlight. Also thinks it is connected to startap but the links do not line up. I think they may be misnamed. Are these equivalent? urn:ogf:network:startap.net:2013:gloriad-startap == urn:ogf:network:startap.net:2013:glo-in urn:ogf:network:startap.net:2013:startap-gloriad == urn:ogf:network:startap.net:2013:glo-out On 2013-09-24, at 10:01 PM, John MacAuley <jmacauley@gmail.com> wrote:

nordu.net The reason being that we don't actually own an DNS names or anything at all (trademark, etc) related to the northernlight name AFAIK.

Depends on the level of hardcode :-) But yes, topology configuration is a bit of mess currently. It might improve, but we did come up with a model that is quite compliciated and largely ignores that there are people out there which have not been following the NSI standard track that have to configure the NSA. I don't think we will ever get something that is completely consistent and correct. The code for topology aggregation and path finding will have to do a lot of sanity checking and be fairly resilient in order to work.
