What is the network bandwidth that the CSA takes in version 4.5?
A. An agent poll can cost 2KB–3KB, if there are no changes. An agent event can cost 3KB–10KB for an average event upload. An agent rule download can cost 50KB–100KB, which depends on the size of the rule set. Agent rule downloads are cacheable. As such, the appropriate use of Cache Engines provide an environment in which there is no effect on bandwidth utilization. In such a case, only one agent download needs to take place for all other agents behind the Cache Engine. When you have enabled the hint message, the MC sends User Datagram Protocol (UDP) packets to the agents. This action only affects bandwidth utilization if Network Address Translation (NAT) has not occurred for the address. The MC detects the hosts that are translated with NAT, and does not hint these hosts. The cost of polling and events is not expected to increase significantly in version 4.5. But, for fair margin, double them. In an environment in which bandwidth utilization is high, polling intervals can save bandwidt
