3 Open packet optical networks defined API Aggregated End to End Management Open Software developed through contributions into open source community Dis-aggregated Entire network acts as a single managed system API API OPEN LINE SYSTEM Transponder is an element; OLS is a separate element API API API API API Every box is a separate element API API Open hardware controlled via open API s with specifications developed via MSA Open API define the communication between open hardware and applications

4 The Need of Simplification On-Line Network Planning Design and Planning is a requirement Strategic Analysis Failure Response What If Scenarios Impact analysis Forecasting Service Life Cycle Management Multi Layer Optimization Online Network Collection and Deployment Common Models Common Interfaces Cross-connections configured by the supporting LSPs OVPN embedding can be performed by the customer, via the Optical Network Embedder or direcly by GMPLS Virtual Service Restoration b R u Pe S pr ly O tie th

5 Industry focus on Control Models Control Models based on Netconf/YANG Although complex Several SDOs and Industry for are working on The Ultimate Model : OpenROADM OpenConfig ONF IETF ITU-T Open Source Models Model Model Model Model Model Model How to plan an Open Optical Network that can be controlled efficiently?

6 Planning and Design Tools Need Open Source transport Design and Planning Tool Many Vendor Specific tools exist Need to break Closed Systems and move to Open systems Tools from design shops exist although costly and complex Open Source tools to Perform service feasibility Vendor agnostic Extend into What IF scenarios Extend into advanced protection / restorations

8 Industry adoption of open line systems Telecom Infrastructure Project API (Rest/RestConf) SDN Controller PLANNER NetConf/YANG Open Optical Packet Transport: This project group will define Dense Wavelength Division Multiplexing (DWDM) open packet transport architecture that triggers a new pace of technology innovation and flexibility, and avoids implementation lock-ins. Open DWDM system includes open line system & control, transponder & network management, packet-switch and router technologies.

9 PSE Working Group Scope We believe that openly sharing ideas, specifications, and other intellectual property is the key to maximizing innovation and reducing complexity Goal is to build an end-to-end simulation environment which defines the network models of the optical device transfer functions and their parameters. Each model shall be validated against the proposed network scenario. The environment must be able to process network models from multiple vendors, and also allow users to pick any implementation in an open source framework. The PSE-WG is moving towards open multi-layer optimization.

10 TIP: Enabling Open Line systems 1. Work out the basics: the Gaussian Noise Model 2. Provide Planners with the toolset to plan the network 3. Enable Orchestrators to run the network
