几种入网模式有什么区别？

这几个模式的意思我已经了解，那么下面摘取的函数中貌似并不是恢复原先的网络，而是以孤立节点的方式入网？

else if ( startMode == MODE_RESUME )
    {
      if ( logicalType == NODETYPE_ROUTER )
      {
        ZMacScanCnf_t scanCnf;
        devState = DEV_NWK_ORPHAN;

        /* if router and nvram is available, fake successful orphan scan */
        scanCnf.hdr.Status = ZSUCCESS;
        scanCnf.ScanType = ZMAC_ORPHAN_SCAN;
        scanCnf.UnscannedChannels = 0;
        scanCnf.ResultListSize = 0;
        nwk_ScanJoiningOrphan(&scanCnf);

        ret = ZSuccess;
      }
      else
      {
        devState = DEV_NWK_ORPHAN;
       ret = NLME_OrphanJoinRequest( zgDefaultChannelList,
                                      zgDefaultStartingScanDuration );
       
      }
    }
