3 01 PoC Description

4 IntroducGon AcGviGes done since last PoC (October 2015): Extending the MW informagon model to cover a broader set of avributes (e.g. configuragon, events, performance informagon) Aligning the microwave model with the ONF core informagon model Moving the focus from OpenFlow to Netconf/YANG, which is much bever in handling informagon models Moving from ONOS to OpenDaylight, since we needed to develop a flexible and open MW NBI Focusing on less prevy but re- usable applicagons (e.g. no stagc network topology required) Upstream all code and applicagons to be used by the community 4

5 InformaGon Model Information model is the key for the work being done: It incorporates inputs from all key MW vendors It provides the ability to read/ configure attributes and alarms/pms handling It includes around 350 MW attributes A subset of 64 priority 1 attributes is covered by 2nd MW PoC INFORMATION MODEL 5

6 Building Blocks 6

7 Building blocks INFORMATION MODEL A key concept used in the PoC are mediators which translate the Netconf/YANG MW informagon model to vendor specific configuragon and vice- versa This enabled working group to save Gme in development and debugging phase This enabled to share code between vendors (all mediators share the same NBI) 7

8 Building blocks INFORMATION MODEL The information model is incorporated into ODL via YANG model plugins In order to support event we extended the ODL *) source code (to be up streamed to the ODL) A testing framework has also been developed which can be used for ODL continues integration Anyone is now able to download ODL, install the MW plugins and run MW apps *) Fork of Beryllium; We intend to contribute to next official release (Boron) 8

9 Building blocks The information model is incorporated into ODL via YANG model plugins In order to support event we extended the ODL source code (to be up streamed to the ODL) A testing framework has also been developed which can be used for ODL continues integration Anyone is now able to download ODL, install the MW plugins and run MW apps 9

10 Building blocks INFORMATION MODEL The mediators developed contain a pure SW implementation enabling the simulation of a MW network without the actual physical equipment Telefonica plans on maintaining a server running the ODL and MW apps leveraging the simulated mediator for future development 10

21 03 Conclusions and Next Steps

22 Summary PoC was completed in 3 month! We presented mulgple WT SDN applicagon: o Topology (planned and dynamic views) o ConfiguraGon & comparison apps o Event handling apps A standard ODL version was used as the controller Mediator were used for translagng the informagon model to vendor specific configuragons (key enabler for our success) All vendors have been able to implement the model 22

23 MigraGon Path and Legacy Networks Using the mediator concept operators will be able to deploy SDN apps in exisgng networks by running mulgple mediators in the cloud to interact with exisgng MW NEs This facilitates to integrate legacy network elements in a smooth way, making the network SDN- ready from day 0 investment protec8on, key for operators Simple monitoring applicagons would smoothen transmission from trials to live network operagon 23

24 Future Steps ConGnuing the implementagon of the WT informagon model based on priority (full 350 avributes) ExperimenGng with the test environment created in Telefonica Germany s lab Formalizing the WT informagon model as an ONF TR document Hardening the SDN applicagons presented Preparing for the next PoC AT&T is hosgng in October 24
