network monitoring shows that network utilization has grow from 30 percent to 70 pencent of maximum capacity in the past year.you add 24 client computers and 1 server within 3 months. you want to reduce network utilization.
the following is configuration of network
servercomputer : 3
clientcomputer : 120 distributed among the 3 servers
network type : 10baset ethernet
protocol :tcp/ip
cable type :category 3 utp
router :none
bridge :none
desired resolution:
you must reduce network utilization by 50 percent
optional desired results:
