about network simulator

Added by Lan Huang 11 months ago

Hello,
When I ran the simulator, I saw some prompt messages.
./network_simulator --nNode=2 --pipeName=/tmp/znode --xgml=2nodes.xgml

xgml found 0 nodes
xgml found 0 edges
success
[XGML parse end]
start simulate

Why?
Many thanks.

2nodes.xgml are shown below.
