BIND9 servers generally sort forwarders by smoothed average response time (srtt) and tries the servers in the sorted order (preferring the "faster" ones, of course). Roughly speaking, it uses the same algorithm as BIND8 (though they don't "ping" the forwarders). If you need further details about how the SRTTs are calculated you may want to refer to the following paper: http://www.sonycsl.co.jp/~kjc/papers/placement.ps --- JINMEI, Tatuya Internet Systems Consortium, Inc. _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
