Despite some recent obituaries published by my peers, software-defined networking is not dead. But perhaps certain aspects of it are dead or dying. If that’s the case, I say: “SDN is dead. Long live SDN.”

Some network operations teams are discovering that they possess a critical asset that can transform enterprises: network data.
ExtraHop Addy applies cloud-based machine learning to network data
By Shamus McGillicuddy on May 7, 2017 3:36:29 PM
IT analytics vendor ExtraHop unveiled a cloud-based service that applies machine learning heuristics to the metadata that its appliances generate from packet stream analysis. The service should give users better visibility into IT service problems and security threats.
The Open Networking Foundation’s New Direction: We Live in a Post-OpenFlow World
By Shamus McGillicuddy on May 6, 2017 3:36:32 PM
The Open Networking Foundation (ONF) recently unveiled plans to redefine itself for the post-hype phase of software-defined networking (SDN). I welcome the ONF’s reset and believe it bodes well for the industry’s future.

Cisco’s Big Data Analytics Vision: Some Data Will Be Distributed Forever
By Shamus McGillicuddy on Jun 12, 2015 12:26:17 PM
Champions of big data analytics extoll the virtues of massive data stores. Enterprises have so much unstructured data that could help them improve operations and generate new revenue, they say. The more bytes, the better. Some might assume that enterprises will simply push every byte they can find into a Hadoop cluster or data warehouse. [...]
Open network management is the focus on spring ONUG meeting
By Shamus McGillicuddy on May 21, 2015 1:19:20 PM
The Open Networking User Group (ONUG) is a community of IT executives that are using their combined buying power to influence the networking industry. Members hail from companies such as Bank of America, JPMorgan Chase and Fidelity Investments. ONUG’s goal is to specify requirements and reference architectures for products that are open, more affordable and more agile than what vendors traditionally offer.
Over its first two years of existence, ONUG has focused on software-defined WAN (SDWAN), network virtualization overlays and network service virtualization (also known as network functions virtualization or NFV). Last week, ONUG convened its spring meeting at Columbia University, where its focus expanded into network management and operations. ONUG introduced three new working groups that will specify open networking requirements and begin testing vendor solutions in various management areas.

SDN and Network Management at ONUG
By Shamus McGillicuddy on May 12, 2015 9:13:36 AM
As an analyst who focuses on network management research, I am particularly intrigued by software-defined networking (SDN). As SDN architectures are deployed in data centers, local area networks and WANs, network management practices will have to evolve. For instance, SDN may make it easier for cloud administrators to provision network services and connectivity for a new application, but how do you ensure that your new programmable network remains compliant with configuration controls and policies? Is your performance management tool able to model and monitor an SDN controller? If you have traditionally relied about appliance-based load balancers and firewalls in your data center, how do you monitor and manage those network functions when they become virtualized services that are as mobile and dynamic as the workloads they serve?
