A traffic network element, TNE, (102) for a network, the TNE comprising:
a traffic engineering network database, TEND, (206) adapted to store network information for the network;
a routing engine (200) is adapted to receive a path setup request message for a label switched path through the network with a first field (310) relating to a link protection type and a second field (316) relating to a shared risk link group;
the routing engine being adapted to process the network information from the TEND to create a network graph, wherein links that do not have the link protection type of the first field (310) of the path setup request message are eliminated from the network graph, and wherein links, that are not diverse with the shared risk link group of the second field (316) of the path setup request message are eliminated from the network graph;
and the routing engine furthermore being adapted to compute a primary path through the network, wherein the primary path comprises links selected from the network graph.
