Nokia HFE17 Human Factors Engineering Conference May 23-24 2017

“We celebrated HFE’s 70th Anniversary at Bell Labs, the home of the creative technologists who pioneered this inter-disciplinary field. We are also encouraging our community’s renewed efforts to shape innovations that enable the human possibilities of technology in today’s connected world.”

“This year’s agenda featured guest speakers from AT&T and Verizon, practitioners in diverse industries from NASA, IBM, Information Builders and Lab Z, experts from MIT and IIT, as well as Bell Labs and Nokia flagship and award winning innovations. This event is organized by Nokia’s Technology Leadership Council in partnership with Bell Labs.”



The above file delivers the event’s agenda and topic abstracts. First, there is a need for thanking everyone involved: speakers, participants, volunteers and sponsors, as well as Nokia’s IT and Real Estate staff. Our conference involved 20 fast paced sessions over two days. 300+ of us participated in this conference from multiple worldwide locations as well as online. Approximately 150 people registered with NokiaEDU, Nokia’s training platform.

I am happy to share that feedback received during and after the event was very positive and encouraging beyond expectations, some of it was incredibly passionate. If you are a peer at Nokia, note that you now have access to HFE17’s communications, conversations and files and the recordings.

Moreover, we are now working on jumpstarting a company-wide community of interest centered on Human Factors and are also gearing for HFE18, which will feature the John E. Karlin Recognition Award. John pioneered HFE at Bell Labs in 1947. He passed away four years ago and his contributions paved the way for user centered innovations.

Nokia’s legendary journey has already passed the 150 year mark and, interestingly enough, more than 95% of us did not carry a Nokia badge four years ago. There are more than 100,000 of us embarked in this endeavor and we all collectively represent 160 nationalities working in more than 100 countries.

Our customers are the world’s communications service providers, governments, enterprises and consumers. We deploy the industry’s most comprehensive set of products, services, as well as licensing opportunities with a patent portfolio featuring in excess of 30,000 inventions.

But, most importantly, our innovations and collective know-how make a decisive difference when we “shape technologies that truly transform the human experience” as technical prowess alone does not suffice. HFE17 was sponsored by Bell Labs and supported by our Technology Leadership Council, a grassroots organization formed by volunteers whose goal is to help foster a culture of innovation that honors Nokia’s renewed commitment to “enabling the human possibilities of technology.”

Humanizing technology is the core belief of those of us working in Human Factors Engineering, whether the job focuses on UX, User Experience, or CX, Customer Experience, dataviz and graphical interfaces or natural language interaction, services or operations, software or hardware, HCI, Human Computer Interaction, or HITL, Human in the Loop Computing, with AI, Artificial Intelligence.

HFE2017’s main objective was to get our community connected so that everyone’s good efforts become as meaningful and impactful as they can be.

I would also like to take this chance to highlight Betsy Cowell’s leadership. I had the pleasure to co-chair this event with her. Betsy’s discipline became instrumental given the scope of the effort and unexpected challenges.

Some of you might recall our first attempt to get HFE off the ground last year. Back then, we encountered technical and scheduling shortcomings when being asked to switch to a new webcasting system yet to be deployed. So, we ended up postponing.

Betsy managed to re-energize this undertaking with the turn of the year. She engaged a small army of volunteers who became key to HFE17’s success. Some just wouldn’t give up even when facing technical and organizational intricacies in the eleventh hour. TLC makes a difference by taking down silos and fostering a culture of collaboration across the company.

New Lean NFV Ops Webinar on Chanel123: “Applying LEAN Principles”


“To maximize the opportunity presented by SDN and NFV we need to start planning operational tasks from a new perspective. In this session Alcatel-Lucent will highlight how Lean principles are being applied to the operationalization of NFV to enable efficient and automated dynamic services. The session will outline a framework for network and service orchestration followed by a demonstration of Lean NFV Ops launching VPN and VoLTE services using an OpenStack based platform.” – Channel 123, “Applying Lean Operational Principles to NFV.”

Lean NFV Ops

60 minutes @ NFV Mashup Series #18
May 29 2015


Just yesterday, Phil and I delivered a new webinar on Lean NFV Ops. Our team would like to thank Layer123’s Robert Jones and Mark Lum  for all of their support with that session. I am also posting the link to an earlier webinar hosted by Valery Noto back in May who will be speaking about the NFV ecosystem at Carrier Network Virtualization in December.

Regarding the above two webinars, both are 60 minutes long. Though, the one on the right was first delivered as a 30 minute live session, which was re-recorded afterwards to provide an extended 60 minute version given growing interest in this topic.

May’s Lean NFV Ops covers a few more use cases, such as smart placement and self-service-ops (SSO) while yesterday’s shares more insights on the underlying Lean principles. This last webinar was scheduled in advance to SDN & OpenFlow World Congress, Alcatel-Lucent being a diamond sponsor. Feel free to see the live version of the Lean NFV Ops demo at that event and take advantage of consulting with NFV experts such as Andreas Lemke. In the meantime, my previous post provides additional materials on Lean NFV Ops, starting with the latest tech talk at GSMA North America just a week ago.


I am now gearing up for IIT’s Real Time Comms in Chicago, my tech talk has been scheduled on Tuesday, October 6 at 2:00 pm. This presentation complements the Lean NFV Ops demo, which Ted East will deliver at 10:00 am, his not-to-miss session title is “Communication Networks Reloaded.”

Last but not least, I’m adding one more quick note on the Lean NFV Ops Roadshow to share that I will be at Dell World in Austin, TX, later this month and Carrier Network Virtualization in Palo Alto, CA, in December. See you there : ) 

Is OpenStack Enough to Support NFV?


“One area receiving a lot of focus this cycle is NFV (Network Functions Virtualization). We’ve started an upstream NFV sub-team for OpenStack that is tracking and helping to drive requirements and development efforts in support of NFV use cases […] The main consumers of NFV are Service providers (telecommunication providers and the like) who are looking to accelerate the deployment of new network services, and to do that, need to eliminate the constraint of slow renewal cycle of hardware appliances, which do not autoscale and limit their innovation. […] The opportunities for OpenStack in the NFV space appear to be huge.”

I just finished listening to Red Hat’s Nicolas Lemieux and CloudBand’s Idan Green who delivered a 30 minute webinar on OpenStack for NFV. This is worth watching. Here is the link to CloudBand’s NFV Mashup Series, which is hosted by Valerie Noto. On that webpage you will find this and 9 other presentations at the time of posting this article.

imageToday’s webinar reminded me of a Bell Labs project that we unveiled at Mobile World Congress in 2012 and further developed for Alcatel-Lucent’s Tech Symposium Silicon Valley. Bell Labs’ “Networked Cloud” PoC (Proof of Concept) helped illustrate benefits behind distributed “cloud-and-network” systems while taking full advantage of CloudBand’s management system and cloud nodes.

I ended up conducting quite a few demonstrations of this project for network operators, industry and financial analysts because predictive analytics fueled with smart algorithms cleverly figured out where to best place a given load anytime. This exercise factored both cloud nodes and network capacity, resource optimization practices, and the actual application requirements and load impact, coupled with deterministic behaviors subject to SLA (Service Level Agreements).

There were several use cases worth considering. Demonstration wise, it made sense to first focus our conversation on the one that could be best visualized and experienced. As an example, sudden demand growth led to the automatic spinning of VM (Virtual Machines), onboarding the right applications, instantiating and deploying a given service (enterprise productivity and collaboration applications for that one demo), and scaling in the process.


  • This scenario’s narrative talked to taking down silos and gaining visibility to improve both server utilization levels and network capacity, all under a centralized management system such as CloudBand. This assumed dramatically shorter lead times, more efficient power consumption and subsequent higher ROA (Return on Assets). Though, the wow factor was delivered by operating under QoS (Quality of Service) parameters, such as latency constrains with a SLA in place, being the result of intelligently placing loads at the edge of the network, closer to the end user for performance sake.

  • Concepts such as monitoring, data correlation, predictive analytics and service continuity would come to the surface under a second use case. Worth emphasizing that both use cases take advantage of the distributed nature of the networked cloud paradigm, which the above map (right screen) helped visualize as the demo progressed.

  • This second use case showed what specific node-and-link combination would be best performing at the time of re-instantiating an application. The objective was to prevent service degradation when network traffic worsens for any reason. There were A/B comparison scenarios facing the same issues, such as a network link being compromised.

  • “A” showed the known behavior of a conventional architecture where the user experience would either be negatively impacted or, alternatively, addressed by means of costly and lengthy over engineering and, therefore, extremely poor and self-defeating ROA. 

  • “B” presented the benefits of distributed systems under the “networked cloud” paradigm, where performance was sustained in an unparalleled cost efficient fashion with loads dynamically placed and relocated as needed; all being back-end stuff that is completely transparent to the end user.

More recently, our EPC (Evolved Packet Core) team conducted a similar NFV demonstration at Mobile World Congress 2014 where the end user’s mobile experience featured video streaming instead. NFV’s distributed architecture is key to also managing not just service continuity and self-healing, but also: resource isolation in multi-tenant environments, security, RAS (Reliability, Availability and Serviceability) and overall service delivery and lifecycle assurance under SLA.

Some other use cases are related to regulatory compliance, which can involve: lawful intercept, local data protection mandates, as well as regional coverage requirements and engineering for no-single-point-of-failure.

FOSS (Free Open Source Software) is becoming a de-facto standard in the telecommunications industry. Some years ago, my team used Euclyptus to deploy and manage cloud computing infrastructure. We needed to create a number of virtual machines and that initiative helped with working on a hybrid AWS-compatible (Amazon Web Services) environment. When projects became more focused on communication networks we then took advantage of CloudStack, which is also positioned as turnkey IaaS (Infrastructure as a Service). Here is a link to a presentation discussing CloudStack in the context of NFV.

More recently, OpenStack has made significant inroads in this nascent space and is part of trials for virtual: CPE (Customer Premises Equipment), CDN (Content Delivery Network), DNS (Domain Name System), AAA (Authentication, Authorization, Accounting), SBC (Session Border Controller), EPC (Evolved Packet Core), and IMS (IP Multimedia Subsystem). In many cases NFV’s MANO (Management and Orchestration) interfaces directly with OpenStack and in some others that is the application’s EMS (Element Management System, or virtual equivalent) job, depending on the workflow.

So, is OpenStack enough to support NFV? I addressed Bell Lab’s “Networked Cloud” research demo as an example where “OpenStack-as-is” does not happen to be yet equipped to address NFV’s own challenges. To be more specific, we are talking about those presented by distributed carrier cloud systems, sophisticated networking, more complex transactions, CPU intensive packet processing and high availability in multi-tenant environments.

As discussed by Nicolas in today’s webinar, NFV injects workload dependencies spanning: control and data planes, signal processing, storage; and more strict requirements for performance, determinism and RAS. These items impact projects shown in the upper part of the above graphic and there are OpenStack Foundation teams looking into these:

Note that Red Hat is also addressing KVM (Kernel Based Virtual Machine) as the open source hypervisor, which creates and runs the VMs; supports libvirt for node management APIs beyond what’s provided by hypervisors; and works with DPDK, Intel’s Data Plane Development Kit with the drivers to accelerate packet processing on x86 platforms.

What follows is the architecture of our integrated joint solution aiming to bring together the best of carrier and IT (Information Technologies) worlds with NFV in mind. This also takes SDN (Software Defined Networking) into consideration.
