In order to manage a network with more than one gateway, spreaded in a territory, you must be capable to centrally manage the configurations, to monitor the “health” of the network, to have data about the historic performance to troubleshoot any issue, etc. For example when you add a device, i.e. provision it on the network, it should be done centrally, and take effect for all the gateways in the network. You must also be capable to monitor which gateways the devices are connected to, along time! instead of checking each gateway individually for a specific device.
