2 Introduction Gluon (A Model-Driven, Extensible Framework for NFV Networking Services) Gluon Aims q Support mul*ple infra and vendors simultaneously q Model-Driven APIs and code genera*on q Agility for new services q Separa*on between APIs and backend Benefits: ü More choice Don t have to find one tool that does everything ü More simplicity The individual API endpoints are much simpler because they only have to do one thing ü More innovation ü Agile method to enable new use cases in telco market ü Accelerated time-to-market of launching new services to Telco customers

3 Gluon Feature summary NOVA Neutron NOVA Neutron Neutron Plugin:ML2 Neutron Plugin Gluon Driver controller controller Compute Node OVS Compute Node OVS VM VM ü It s difficult to extend neutron s networking API s to address several networking services. ü Gluon introduces a simple modelling framework q To test different networking services (networking API s) q Reduces time to market q Provides flexibility to integrate any controller Page 3

4 Gluon Present Support ü Gluon relies on the Neutron s Plugin frame. ü Gluon ensures that the L3 service is flexible. ü Adopts a model driven approach ü Data models are described using YAML ü Uses tool to generate corresponding networking API s called Proton. ü Controller needs to define an adaptive shim layer to communicate with the Proton server using etcd. ü Already support L3VPN networking API s.

Between two independent ONOS controllers establish BGP-EVPN session. Form OVS VxLAN tunnel. Different tenants establish BGP EVPN session and does not affect each other.
