* SDNi Aggregator: Northbound SDNi plugin acts as an aggregator for collecting network information such as topology, stats, host etc. This plugin can be evolving as per needs of network data requested to be shared across federated SDN controllers.
* SDNi REST API: REST API view autogenerated and accessible through RESTCONF to fetch the aggregated information from the northbound plugin – SDNi aggregator.The RESTCONF protocol operates on a conceptual datastore defined with the YANG data modeling language.
* SDNi Wrapper: SDNi BGP Wrapper will be responsible for the sharing and collecting information to/from federated controllers.
+* SDNi UI:This component displays the SDN controllers connected to each other.

* SDNiWrapper is an extension of ODL-BGPCEP where SDNi topology data is exchange along with the Update NLRI message. Refer http://tools.ietf.org/html/draft-ietf-idr-ls-distribution-04 for more information on NLRI.
* SDNiWrapper gets the controller’s network capabilities through SDNi REST API and serialize it in Update NLRI message. This NLRI message will get exchange between the clustered controllers through BGP-UPDATE message. Similarly peer controller’s UPDATE message is received and unpacked then format to SDNi Network capability data, which will be stored for further purpose.
