Re: [onos-dev] Dijkstra

I’m not sure that even your work-around will work. I think you’re just getting lucky with the first path returned being the same. I think that the only reliable way would be to modify the reactive forwarding app so that it programs both directions at the same time on the same switch and swap ingress/egress ports. This too has some limitations in certain environments, e.g. optical.

Hello everyone,

I have just realized that the reactive forwarding app, which uses Dijkstra as the default algorithm, doesn't necessarily take the same path when the packets are sent from the destination back to the source and the topology leads to this situation, as shown in the image. I have thought of setting the max number of paths to find to 1 and it works, but is it the best way to do it? Thanks in advance.

Best regards
