9. Add SDN to Elements with no Control Plane ©2014AT&TIntellectualProperty.Allrightsreserved.AT&TandtheAT&TlogoaretrademarksofAT&TIntellectualProperty. Use ONOS to control optical networks Gain experience with global graph abstraction Transponder Transponder Flexibleopticalnetwork DC 1 DC 2 OpticalNetworks are typicallyprovisionedtoday, butshouldhaveacontrol planetomorrow. DataCenterslook forbandwidth schedulingtoaugmentexisting capacityforbackups,sync, moves,e.g.HaaS. Control is similar to that of packet networks, except flows==wavelengths. OpticalNetworkshaveunique concerns,butcanbeexpressed inanetworkgraphabstraction. 9 OpenNetworkOperatingSystem
10. Add SDN to New Network Layers ©2014AT&TIntellectualProperty.Allrightsreserved.AT&TandtheAT&TlogoaretrademarksofAT&TIntellectualProperty. Use ONOS to Control NFVI Fabric The new layer is the “fabric” used to interconnect VNFs Borrowing from Data Center approaches, this fabric is well suited to SDN control This can support many legacy elements AND all- new applications 10 CentralOffice Orchestration VNF IO IO VNF Metro Link(s) ONOS
