Global SDN-IP Deployment

NCTU SDN-IP Deployment 2

About SDN-IP


Allows an SDN to connect to external networks on the Internet using standard Border Gateway Protocol (BGP)

From a BGP perspective, SDN network appears as a single Autonomous

System (AS)– SDN-IP application provides integration mechanism

between BGP and ONOS.– SDN-IP behaves as a regular BGP speaker

From ONOS perspective, SDN-IP is just an ONOS application

– uses ONOS services to install and update appropriate data forwarding rules

Design Goal of SDN-IP


Compatibility: can be integrated with networks that already use BGP

Operational Flexibility:Can run on one or multiple ONOS instances and Can be used in a variety of BGP deployment scenarios

(full-mesh, Route Reflectors, confederations, …) High Availability (HA): provides HA within SDN-IP itself Scalability: Large-scale SDNs can be controlled by using

BGP-based Confederations and multiple ONOS clusters, each running SDN-IP

Protocol Compatibility and Vendor Independence:standard BGP protocol and not vendor-specific

extensions.
