| 3 | The [[NCd|Network Characterization daemon]] (NCd) uses "ubus":http://wiki.openwrt.org/doc/techref/ubus (the "OpenWrt":http://www.openwrt.org micro bus architecture) to communicate with the [[NCui|Network Characterization user interface]] and with other daemons and applications. This page documents the ubus namespace of the NC, with the available procedures and several examples. |
