New issue 50 by guy.robe... at gmail.com: Pathfinding functionality review
http://code.google.com/p/ogf-nsi-project/issues/detail?id=50

Description of Issue:
Pathfinding.  Currently the 'network-internal' path-finding is delegated to  
the network - this is not currently exported - how should this be done?
TK: Static vs. dynamic information - topology is more static, connections  
and vlans are more dynamic. To scale well these should be handled in  
different ways.
JS:
Jeroen: Also an issue with vlan blocking found at Netherlight... this also  
needs to be solved.  'Label' (vlan) swapping needed based on negotiation  
between neighbouring networks.
Jerry: negotiation in tree mode happens at RA when it has decided which  
connections point is needed.
Jeroen:  This means that we need some vlan information in NSI request.
Jeroen: one STP per vlan does not scale.
Jeroen: we need to have a way in the topology to express which vlans are  
available and which are not.
