# [AG-TECH] Minimum Bandwidth Requirements

```An AG node typically generates between 3 and 6 megabits/second.

The amount of traffic coming in to an AG node depends on how many other AG
nodes are interacting.  Each node receives the traffic from all the other
nodes.

You can estimate the inbound traffic to a node in a conference by this formula:

inbound traffic in megabits/sec =
average outbound traffic across the conference *
total number of participating nodes - 1

For example, consider a conference where three nodes are participating, and
each node is generating an average of 4 megabits/second.  Each node will be
transmitting 4 megabits/second, and each node will be receiving 4 megabits
sec * ( 3 nodes total - 1 node local = 2 external nodes) = 8 megabits/second.

Another example: consider a conference where there are 10 nodes
participating, and each node is generating 3 megabits/second
outbound.  Each node will receive 3 megabits/second * ( 10 nodes total - 1
node local = 9 external nodes) = 27 megabits/second.
