Cloud or stupid network Old smart network Modern stupid network

The router is actually smart! routing and forwarding routing prefix, prefix age, link bandwidth, available bandwidth, i/f queue, corruption loss, congestion loss, L2 address, signal strength, retransmission counter... operation uptime, location, temperature, time zone, i/f description, CPU load, operator’s contact....
