Good morning, We belong to i2CAT Foundation. We are currently working in GEANT3 project. We are studying some Network Topology Description protocols, one of them is NDL. The aim of our work is to compare some Network Topology Description protocols with the one that we are using in our tool AutoBAHN (Automated Bandwidth Allocation across Heterogeneous Networks) and obtain some conclusions of how to improve it. We are mainly interested in NDL Topology and Domain Schemas. We had a look in the UML diagram file, but we noticed that you define some entities but those entities has no attributes. For our work, will be very helpful to know the attributes of each class. Could be any possibility that you can provide us this information? Furthermore, we would like to now which is the current state of the project if that is possible Thanks in advance. -- Jordi Jofre Ponsati i2CAT Foundation / Network Technologies Cluster (CTX) C/ Gran Capità 2-4, office 203, Nexus I building 08034 Barcelona, Catalonia (Spain) T: +34 93 553 2510 / F: +34 93 553 2520
