Quizplus · Accepted Answer

The primary practical difficulty with multicasting is that it requires routers to support multicasting. This is because multicasting involves sending a single copy of data to multiple recipients, which requires routers to replicate the data at appropriate points in the network to reach all intended recipients. If routers do not support multicasting, this efficient distribution mechanism cannot be utilized.
