Explanation:
“Traffic analysis and trend analysis are forms of monitoring that examine the flow of packets rather
than the actual content of packets. Traffic and trend analysis can be used to infer a large amount
of information, such as primary communication routes, sources of encrypted traffic, location of
primary servers, primary and backup communication pathways, amount of traffic supported by the
network, typical direction of traffic flow, frequency of communications, and much more.” Pg 429
