Anees Shaikh
Anees Shaikh is with the Global Networking team at Google where he works on software systems to support network management, cloud networking, and routing security in Google’s production networks. Prior to joining Google, he was the Chief SDN Architect in the System Networking product group at IBM, and a research lead at the T.J. Watson Research Center working in all three major divisions (software, services, and systems) of IBM Research.
Anees has published widely in the areas of networking, cloud computing, and system management, and has been an invited speaker in numerous industry forums. He has also been active in a number of open source and standards efforts, including ONF, OpenStack, and IETF, as well as helping to found the OpenDaylight and OpenConfig projects.

Experiences with Modeling Network Topologies at Multiple Levels of Abstraction
Martin Pool
Xiaoxue Zhao
17th Symposium on Networked Systems Design and Implementation (NSDI) (2020)
Preview abstract
Network management is becoming increasingly automated,
and automation depends on detailed, explicit representations
of data about both the state of a network, and about an operator’s intent for its networks. In particular, we must explicitly
represent the desired and actual topology of a network; almost all other network-management data either derives from
its topology, constrains how to use a topology, or associates
resources (e.g., addresses) with specific places in a topology.
We describe MALT, a Multi-Abstraction-Layer Topology
representation, which supports virtually all of our network
management phases: design, deployment, configuration, operation, measurement, and analysis. MALT provides interoperability across software systems, and its support for abstraction allows us to explicitly tie low-level network elements to high-level design intent. MALT supports a declarative style that simplifies what-if analysis and testbed support.
We also describe the software base that supports efficient use of MALT, as well as numerous, sometimes painful
lessons we have learned about curating the taxonomy for a
comprehensive, and evolving, representation for topology.

Data Models for Optical Devices in Data Center Operator Networks
Nancy El-Sakkary
OSA Technical Digest, OSA Publishing (2019)
Preview abstract
Standardized, vendor agnostic data models deliver major operational benefits. OpenConfig has been implemented on multiple platforms and is an ideal data model to take advantage of these benefits. This document provides an overview.

Despite remarkable developments in open networking and SDN, a critical element of operating any network, the management plane, remains an afterthought. As the control and data planes open up, users are still firmly locked into a myriad of proprietary CLIs, APIs, and extensions to configure and monitor the network. In this talk, the presenters will describe a new way of managing, monitoring, and testing networking systems that is vendor-independent, comprehensive, and devised by a broad set of network operators collaborating with equipment and software vendors. The technologies in this ecosystem are designed for automated management systems and include open source data models, development tools, management protocols, and reference implementations. With these tools, the industry have an open, end-to-end open architecture that finally brings network management into the modern SDN era.

Vendor-neutral Network Representations for Transport SDN
Vinayak Dangui
Proc. of Optical Fiber Communication Conference (2016)
Preview abstract
We describe a model-based approach for building a transport SDN platform that uses operator-defined data models to build common APIs for managing multi-vendor optical networks consisting of terminal devices and line systems.

Bringing SDN to the Management Plane
Networking @Scale, Menlo Park, CA (2015)

Google’s OpenConfig and the need for a network configuration framework guided by software-defined networking principles, with a focus on developing common models of network devices, and common languages to describe network structure and policies.
View details
Preview abstract
The networking industry has made good progress in the last few years on developing programmable interfaces and protocols for the control plane to enable a more dynamic and efficient infrastructure. Despite this progress, some parts of networking risk being left behind, most notably network management and configuration. The state-of-the-art in network management remains relegated to proprietary device interfaces (e.g., CLIs), imperative, incremental configuration, and lack of meaningful abstractions.
We propose a framework for network configuration guided by software-defined networking principles, with a focus on developing common models of network devices, and common languages to describe network structure and policies. We also propose a publish/subscribe framework for next generation network telemetry, focused on streaming structured data from network elements themselves.
