Hi Omprakash, Thanks a lot. Thus, I guess the CtpInfo.getEtx() will return a routing cost from transmitters to root; and the CtpPacket.getEtx() will return a routing cost from the root to transmitter; therefore, in order to find the best path to next route, the CtpRoutingEngineP using the CtpInfo.getEtx()? Am I right?
Thanks and really sorry for a late reply.
