OpenDaylight's SDN Interface Application (ODL-SDNi App) is a project slated for the OpenDaylight's Helium software release, which is expected in fall 2014. The project's purpose is to enable the inter-SDN controller communication by developing software-defined networking interface (SDNi) as an application.
SDNi aims to simplify network traffic to the OpenDaylight controller in multivendor environments.
Slated for OpenDaylight's next software release, Helium, SDNi will comprise:
1. SDNi Aggregator: Northbound SDNi plug-in acts as an aggregator for collecting network information such as topology, stats, host, etc. This plug-in can evolve per the needs of network data requested to be shared across federated SDN controllers.
2. SDNi RestAPI: SDNi REST APIs will be implemented to fetch the aggregated information from the northbound plug-in -- the SDNi Aggregator. New SDNi RestAPI will be developed specific to ODL for supporting SDNi application.
3. SDNi Wrapper: SDNi BGP Wrapper will be responsible for the sharing and collecting information to/from federated controllers.
The ODL-SDNi app can be used for bandwidth on demand across inter-SDN federated controllers. In a multivendor environment, network traffic would need to be orchestrated across intra-/inter-domain subnets of the SDN controllers. The mandate is of an east-west communication that enables SDN controllers across subnets to exchange network information within the purview of defined policies.
