 # MediatorServer
 
 ## Description
-The mediator server is the physical device on which multiple instances of the [mediators](mediator/) are running. Additionally a small webserver provides an API to control and create the mediators via HTTP-API. These mediators are translating the requests and responses between the SDN-Controller(netconf) and the device(snmp). Because of the restricted snmp protocol (port 162 only) we have to implement a prerouting automatism that forwards the alarms sent by the devices to another local port so that each mediator only gets the alarms of its device.

 SDN-R adds features and functionality to the OpenDaylight-based ONAP controller 'SDN-C'. It is built on the Common Controller Framework to control and manage wireless resources. Wireless resources are virtual network functions (e.g. vBBU, vEPC) or physical network functions (e.g. microwave and millimeter wave radios, eNodeB, RRH, DAS equipment).
 
-SDN-R is integrated into ONAP. Therefore it is interfacing with PNFs and VNFs and with other ONAP components, such as A&AI, DCAE and SO.

 ## Views
 
-The graphical user interfaces is divided in four sections.
+The graphical user interfaces is divided in three sections.
 
 ### Required Network Elements
 
 Required Network Elements are physical network functions, which are planned or expected in the network. This means the identifier, IP addresses and its required configuration is well-known and available in a planning database or in ONAP A&AI.
 
+This view also offer to manually configure/mount the device with the '+' icon. The SDN controller will then start connecting the Netconf server.
+
 ### Unknown Network Elements
 
 Most of the physical network function support an automatic registration procedure to the SDN controller. It may  happen, that devices are connected to the SDN Controller but not available in planning data. 
 
 It might be a normal occurrence for very cheap devices, where an entire planning process to too expensive. But is may also happen that the identifier used in planning process differ from the identifier currently configured in the device. 
 
-### Mount NetConf Server
-
-The view offer manually configuration of a device. The SDN controller will then start connecting the NetConf server. 
-
 ### Connection Status Log
 
 The log lists the connections status changes between SDN Controller and NetConf servers (devices).

 An alarm status bar on top of each graphical user interface informs the operator about the health status of the network.
 
 The OpenDaylight DLUX web application uses web sockets for updating the graphical user interface in case of Problem Notification (devices) and Connection Status Notifications (ODL).

+# Inventory
+
+The application offers basic inventory management of devices supporting ONF-TR-512. 
+
+The view displays the inventory data of the network element - basically serial-numbers and part-numbers are displaced according to the containment of the equipment.
+
+##### Inventory Export:
+
+As the default pagination size is set to 10, when you export the data only first 10 rows or the first 10 filtered rows shown on the page will be exported to a file.
+The inventory export allows the export of up to 1000 entries, when the pagination size is increased to 1000. 
+So, It is recommended to change the pagination size 'Rows per page' to 1000 if you want to export the complete Inventory data. 
+
+To export the Inventory data:
+The behaviour is different depending on the browser:
+
+a) Some browsers allows you to save the file with the predefined name export.csv. In case your browser does not offer this function please use 'Save as..' 
+   option and define the filename with extension csv. 
+
+b) Some browsers saves the file automatically with the alphanumeric name without an extension. In such case please go to the downloaded file location and rename the file
+   with the extension after the download. (eg: export_file.csv)

-Performance Monitoring values measured by the devices are necessary to analyze and optimize the network. Therefore the application automatically retrieves all historical performance values from the devices and stores them in a data base. The client part just retrieves the values from the database and displays them in graphical and/or grid views.

-## Current performance values
-
-After selection of a connected PNF supporting ONF-TR-532 and an physical interface, the application collects the current performance values directly from the device and displays then in table views.

-## Performance history values

-After selection of a connected PNF supporting ONF-TR-532 and an physical interface, the application collects the received and centralized stored performance values for this interface and displays then in table views.

-After selection of two air-interface creating an air-interface-link, the application collects the received and centralized stored performance values for this link and displays the data in diagrams and table views.
