Introduction

WebUI is a graphical user interface that is available to the connected devices. It acts as an application running on the RDK-B stack and performs the functions of a device management interface similar to TR69 & SNMP. A user can monitor and modify RDK-B feature settings/rules using WebUI. It is a client–server application, client runs in a web browser (as part of devices connected over LAN) and Lighttpd on the RDK-B stack acts as server. The functions in WebUI are defined in C and are called from PHP using ZEND_API. PHP and the Zend Engine manage [exchange] variables internally over the D-Bus.
