1. Project Proposals: ODL-SDNi App

2. 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

3. ODL-SDNi App – SDNi Wrapper
Network 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…)
Dependency
Need enhancement in ODL-BGP for:
NLRI update message implementation (only inbound Update message implemented)
End To End session establishment between BGP speaker
We are in discussions with Dana Kutenicsova and Robert Varga
RFCs Referred
SDNi:draft-yin-sdn-sdni-00.txt
Border Gateway Protocol : RFC 4271

4. Use Case: Bandwidth on demand across inter-SDN Federated Controllers
ODL-SDNi App
Use Case: Bandwidth on demand across inter-SDN Federated Controllers
Business Challenge
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
