auto discovering of devices included in monitored networks and adding
		them to the managed device database;
		
 
visualization of monitored network topologies according to data
		gathered from managed devices through SNMP protocol;
		
 
monitored device states visualization (states of network interfaces,
		BGP sessions);
		
 
visualization of responses of monitored devices for ICMP ECHO
		packets sent by the management station (similary as ping command);
		
 
creation objects that represent service, node etc., which state depends
		on states of other objects and services stored in the database;
		
 
running directly from presented topology maps the most suitable control
		panels for selected devices and other graphic applications of David system;
		
 
designing graphic interfaces to control network devices that supply
		SNMP protocol; appearance of each interface and its functionality depend on
		an end-user invention (every control panel is written as a separate file);
		
 
real-time monitoring (considering speed of computer networks and polling
		interval) of devices work parameters and controlling its work, through
		generated application - control interface to a particular device;
		
 
visualization of network device work parameters through a generated
		application - interface to a particular device;
		
 
collecting current parameters of monitored devices work using SNMP protocol;
		
 
presenting collected data as graphs available in Web site;
		
 
sending collected data to Operation Manager;
		it makes possible to detect potential problems in early phase.
		
 
management of David system user accounts (creation and modification of
		user accounts).
		
 
management of David system user groups (creation and modification of
        	user groups and classifing user groups as selected groups);
 
creation an access policy to component elements of the system for
        	particular users and user groups.
