Simplifying Transport Network Operations With Declarative, Vendor-Neutral Configuration Management

Tuesday, 5 March, 11:00-12:30
Theater III, Hall G
Session organized by OpenConfig

Session Description

Operating large, multi-vendor transport networks using traditional management interfaces (TL1, CLI, SNMP, etc.) presents a number of challenges to automation including dealing with vendor-specific conventions, serialized, imperative configuration, and the lack of well-defined machine-to-machine APIs. A model-driven, declarative management approach based on the OpenConfig ecosystem provides a simplified, vendor-neutral framework for configuring network devices, enabling new levels of automation and scalability. This panel will include the perspective of both users and technology providers on the benefits and best practices for OpenConfig-based configuration management.

Eric Breverman, Staff Network Engineer, Google

Eric is the technical lead of automation and software defined networking for Google's production optical network. Currently, his main objectives are to drive the industry to adopt a modern machine to machine approach for interacting with optical devices and to implement these platforms into Google's software stack. Specifically, this entails monitoring with OpenConfig based streaming telemetry and pushing declarative configuration via OpenConfig. A key aspect of his work has been contributing and educating others on the optical OpenConfig models. Multiple vendors and platforms have adopted this approach and Google has been the first in the industry to fully implement them into the live production network at scale. This has been a key enabler in allowing Google to achieve unprecedented scale and growth in the optical network. Eric holds a bachelor's degree in Electrical Engineering from California Polytechnic State University, San Luis Obispo.


Sai Chen, Alibaba, China
