Upgrading Juniper MX Networks from 100GbE to 400GbE: What Engineers Need to Know
Moving a production network from 100 Gigabit Ethernet to 400 Gigabit Ethernet sounds simple on paper:
Replace a 100G interface with a 400G interface and get four times the bandwidth.
In a real carrier or data-center network, however, the interface is only one part of the equation.
