ODL-SDNi App – ODL East-West Interface

ODL- SDNi App scope/coverage

SDNi Aggregator Northbound SDNi plugin acts as an aggregator

for collecting network information such as topology, stats, host etc.

Plugin can be evolved as per needs of network data requested to be shared across federated SDN controllers

SDNi RestAPI SDNi REST APIs will be implemented to fetch

the aggregated information from the northbound plugin – SDNi aggregator

New SDNi RestAPI will be developed, specific to ODL for supporting SDNi application

SDNi Wrapper SDNi BGP Wrapper will be responsible for the

sharing and collecting information to/from federated controllers

ODL-SDNi App – SDNi WrapperNetwork parameters that would be exchanged as part of SDNi communication (a sample)

Topology Data: Controller Ip Address Links Nodes Link Bandwidths MAC Address of switches Latency Host IP address

QoS Data Packet Loss rate Packets Transmitted Packets Received

Extendable to: Network topology Network events User defined request information QoS requirements from user application

request Integral infrastructure status (IT, energy

consumption…)

Use Case: Bandwidth on demand across inter-SDN Federated Controllers

ODL-SDNi App

In the multi-vendor environment, network traffic would need to be orchestrated across intra-/inter-

domain subnets of the SDN controllers.

The mandate is of a east-west communication that enables SDN controllers across subnets to

exchange network information within the purview of defined policies

Inter-SDN controller (multi-vendor) communication – exchange of network parameters needs to be

per pre-agree interface specifications
