5246.0. "UCX's Cluster Load balancing mechanism AD2??" by EWBV06::HAKUTA (a network engineer SPS/MCS/JPN) Wed Feb 19 1997 11:55

	Hello!!
	
                The sequel to a Topic 5223.

        1. 
             I would like to know a condition for metric request on BIND 
	     server.

		I understood a condition.

       	       	    Metric request is transmit from BIND client to BIND 
		    server if not entry a metric information in BIND server. 
                    
		Please teach me other condition.

                  Metric request is transmit from BIND client to BIND
		  server if periodic.

		  How log doses it takes an interval time?




        2. 
		
             I would like to know following case.


                    BIND server          metric server
                      --+--                 -+-
                        |    metric request  |

           Metric    -> |                    |
          calculate     |                    |
          and           |                    |
          stored to     |                    |
          cache         |                    |

                        |                    |

              timeout   |                    |
              and       |                    |
         recalculated 


		How long doses it takes between pint A and pint B?

		How long doses it takes between pint C and pint D?
