Hello Alper,
I agree with your point, but it means that the total cost of
the distributed solution is even more expensive.... right?

Hi Charlie,
- It is claimed that a centralized architecture requires more resources
than a distributed architecture. This is usually false. For instance,
if a centralized node requires 100 units, and 100 distributed nodes each
require 1.03 units, the distributed architecture requires 3 more units
overall.
This would be true for tasks that can be performed either on the distributed
node or on the central node.
But the essential task for DMM systems, IP forwarding, is not of that nature.
In centralized architecture, that task needs to be performed *both* at the edge
node and also at the central node (and in fact even in between) before the
packets hit the Internet/mobile device.
Even so, the additional expense of the distributed architecture
would often be a bargain for reasons of redundancy, resiliency, etc.
