Hi Yuhang, There is no way to identify the directions of the ports since the current setup allows you to potentially declare any topology, not just a mesh. The way I typically do this is the following: In GarnetNetwork_d.cc, when the router ports are being added (makeInternalLink etc), you can set some "direction" field in each port by inferring it from the source and destination router ids. And then later you can use these port directions to implement odd-even routing.
