Open, Multi-vendor Networks - Design, Management and Operations

Wednesday, 11 March 12:00 - 13:00
Theater II

Session organized by OpenConfig

Session Description
Large-scale transport networks continue to evolve toward increasingly open and programmable data planes and management interfaces, coupled with greater interest in hardware and software disaggregation that enable greater flexibility and efficiency. These trends require open, multi-vendor software tools for the entire network lifecycle, from design and planning, to provisioning and operations, then migration to new technology. In this session, panelists will review and discuss some of the latest developments in software to help operators design and manage multi-vendor heterogeneous, disaggregated networks at scale.

Open Optical Design Software

Openness and interoperability are key issues for Orange, which motivated our contribution to GNPy open source software. Its algorithms and models are open and support multivendor cases. Now, Orange uses GNPy for planning, studies, procurement and purchasing process preparation and analysis and explores its use for network automation.

Acceleration Strategies for Productization of Open Multi-vendor Networks

In order to successfully deploy in scale open and multi-vendor networks, Mr. Voruganti believes all service providers must take advantage of the innate value of disaggregation. The umbrella of disaggregation architecture offers the service providers the ability to select the best in class technology building blocks with different innovation cycles without compromising on performance and time to market. However, with plethora of building block choices from multiple vendors, qualifying solutions can drastically delay productization of multiple vendor solution networks. The industry must continue to build and leverage open automation and orchestration tools which are vendor independent and which can integrate the open planning tools and the open APIs to accelerate the validation of the end to end architecture involving the ever evolving building blocks from multiple vendors. Through active collaboration from all stakeholders, the networking industry can truly take advantage of this disruptive architecture.
