Industrial Networking Enabling IIoT Communication white paper
Working consortia of companies and individuals researching a technology provide great guidance for users of the technology—usually in the form of white papers. The Industrial Internet Consortium (IIC) has been especially prolific lately. This means many companies and individuals see the importance of donating time and expertise to the cause.
The IIC has announced the IIC Industrial Networking Enabling IIoT Communication white paper. The paper serves as an introductory guide on industrial networking for IIoT system designers and network engineers, and offers practical solutions based on key usage scenarios.
“Industrial networking is the foundation of IIoT,” said David Zhe Lou, Chief Researcher, Huawei Technologies. “There are many choices of networking technologies depending on the application, the industrial network, deployment situation and conditions, but there is no universal or preferred industrial networking solution.”
Industrial networking infrastructure and technologies reside at the IP layer and below, and enable industrial assets, such as machines, sites and environments, to connect to the business professionals supporting applications across a wide range of industry sectors. Industrial networking technologies provide the foundation for applications that enable manufacturing productivity and profitability.
“IIoT applications have different needs depending on the industrial application and therefore demand robust, flexible and secure networks,” said Cliff Whitehead, Business Development Manager, Rockwell Automation. “This white paper will help IIoT system designers and network engineers understand the tradeoffs they can consider when designing an industrial network architecture that will be a strong foundation for current and future IIoT scenarios.”
Industrial networking is different from networking for the enterprise or networking for consumers. For example, IIoT system designers and network engineers need to make decisions about using wired or wireless communications. They have to figure out how to support mobility applications such as vehicles, equipment, robots and workers. They must also consider the lifecycle of deployments, physical conditions, such as those found in mining and agriculture, and technical requirements, which can vary from relaxed to highly demanding.
“Networking technologies range from industry-specific to universal, such as the emerging 5G, which meets diverse industrial needs,” continued Jan Höller, Research Fellow at Ericsson. “Industrial developers need guidance when devising solutions to select the right networking technologies, and this white paper is the first step to providing the missing methods and tools.”
The Industrial Networking Enabling IIoT Communication white paper sets the stage for the Industrial Internet Network Framework (IINF), which will complement the Industrial Internet Connectivity Framework (IICF) by detailing requirements and best available technologies for the lower three layers of the industrial internet communication stack.

The Industrial Internet Consortium is a program of the Object Management Group (OMG).
The Industrial Internet Consortium (IIC) generates much useful information promoting awareness and technical tips about, well, the Industrial Internet of Things. Last week I had the opportunity to speak to the authors of a new white paper, ”Introduction to Edge Computing in IIoT”, Todd Edmunds, Senior Solution Architect, IoT, Cisco, and Lalit Canaran, VP, SAP.
The paper provides practical guidance on edge computing, architectures and the building blocks necessary for edge computing implementations. The IIC is also planning to release an Edge Computing Technical Report that will contain in-depth technical information in the coming months.
This paper is not a C-level generic paper evangelizing the concept, but rather practical advice designed to open the discussion followed by technical details targeted to those to whom the C-level executives might tell, “I have been reading about the IIoT. This looks like something we should be jumping into.”
We discussed how the edge should be defined by the business objective rather than the technology used. Using computing at the edge improves performance of the system when bandwidth could be the constraining factor for using the cloud.
As the edge gets more powerful, they told me, the role of the cloud will shift to one of orchestration of remote sites plus storage.
“Many companies are wanting to realize the business benefits that edge computing is purported to provide but are unsure where to begin or how to realize those advantages. The IIC has been at the vanguard of the industrial internet since its inception, and edge computing has been an integral part of driving the transformational outcomes that go along with it,” said Edmunds. “With the publication of this white paper, we provide practical guidance on where the ‘edge’ is and the key drivers for implementing edge computing. We also provide detail on edge computing architectures and real-world use cases.”
“Almost every use case and every connected device on the industrial internet requires some sort of compute capability at its source at the edge,” said Dr. Mitch Tseng, Distinguished Consultant, Huawei Technologies, and co-author of the white paper. “Oil rigs in remote locations have sensors gathering data but they need to be mindful of the challenges of data transmission because of bandwidth issues or the cost of transmission. The white paper is a first step in the development of an industrial grade ‘cookbook’ for edge computing.”
“Organizations adopting an IIoT strategy need to understand what data is available, how to use it to drive industrial processes and how to orchestrate, manage and secure data/compute,” said Canaran. “This paper and subsequent technical report will enable enterprises to unlock the full potential of the edge-cloud continuum and drive the business outcomes enabled by next-generation IoT devices, machine learning and AI.”

Security comes first to mind whenever we begin discussing connecting things in an industrial setting. And, of course, nothing connects things like the Industrial Internet of Things (IIoT). One place we often fail to consider in our security planning is at the endpoint of the network. Organizations and companies have been providing valuable assistance to developers by releasing best practices white papers. Here is one from a leading Industrial Internet organization.
The Industrial Internet Consortium (IIC) announced publication of the Endpoint Security Best Practices white paper. It is a concise document that equipment manufacturers, critical infrastructure operators, integrators and others can reference to implement the countermeasures and controls they need to ensure the safety, security and reliability of IoT endpoint devices. Endpoints include edge devices such as sensors, actuators, pumps, flow meters, controllers and drives in industrial systems, embedded medical devices, electronic control units vehicle controls systems, as well as communications infrastructure and gateways.
“The number of attacks on industrial endpoints has grown rapidly in the last few years and has severe effects. Unreliable equipment can cause safety problems, customer dissatisfaction, liability and reduced profits,” said Steve Hanna, IIC white paper co-author, and Senior Principal, Infineon Technologies. “The Endpoint Security Best Practices white paper moves beyond general guidelines, providing specific recommendations by security level. Thus, equipment manufacturers, owners, operators and integrators are educated on how to apply existing best practices to achieve the needed security levels for their endpoints.”
The paper explores one of the six functional building blocks from the IIC Industrial Internet Security Framework (IISF): Endpoint Protection. The 13-page white paper distills key information about endpoint device security from industrial guidance and compliance frameworks, such as IEC 62443, NIST SP 800-53, and the IIC IISF.
Equipment manufacturers, industrial operators and integrators can use the Endpoint Security Best Practices document to understand how countermeasures or controls can be applied to achieve a particular security level (basic, enhanced, or critical) when building or upgrading industrial IoT endpoint systems, which they can determine through risk modeling and threat analysis.
“By describing best practices for implementing industrial security that are appropriate for agreed-upon security levels, we’re empowering industrial ecosystem participants to define and request the security they need,” said Dean Weber, IIC white paper co-author, and CTO, Mocana. “Integrators can build systems that meet customer security needs and equipment manufacturers can build products that provide necessary security features efficiently.”
While the white paper is primarily targeted at improving the security of new endpoints, the concepts can be used with legacy endpoints by employing gateways, network security, and security monitoring.

Cyber security is on the mind of all of us. The Internet of Things, digital factory, Industry 4.0, and all of the new strategies for improving manufacturing and production efficiencies contain a common element. They all inherently contain connections that can possibly be attacked by cyber hackers.
We are all concerned with foreign government attacks that can blow up facilities, poison water supplies, and other doomsday scenarios we can imagine. However, most hackers are really after a pay day. A big pay day. They can hold your process—and your business—hostage until you fork over some cash.
I have had many interesting cybersecurity conversations with Albert Rooyakkers, founder and CEO of Bedrock Automation. He has built a powerful controller with security designed in from the chips on up. He’s been touting the “Open Secure Automation (OSA)” platform lately.
The company just released a new white paper on the cyber security vulnerabilities and defense of industrial control systems. The 20-page document, Securing Industrial Control Systems – Best Practices, covers the threat landscape and presents a holistic approach to defending it, including assessing risk, physical security, network security, workstation and server security, as well as the fundamentals of OSA.
I just read it and found it informative. You can download it here along with the previous three papers in the series.
“As we discuss cyber security with users of automation, we find that many are aware of the threat potential but are not sure if they are doing enough to protect themselves. We saw the need for a technical paper that explains both the mindset and motives of an attacker, as well as the tools and technologies of defense. This paper defines the issues in a practical, holistic way while providing recommendations on how to begin and sustain best practices for cyber defense,” said Rooyakkers.
The first half of the paper covers conventional cyber security practices that apply to all industrial control systems. It provides an assessment of the threats, including drive-by attacks, advanced persistent threats (APTs), espionage, process attacks, and ransomware. It also looks at assessing the related risks, with an introduction to Process Hazards Analysis (PHA) and Hazards and Operability (HAZOP) methodologies used to identify malfunctions that might harm people, the process, or the environment.
To assist with risk assessment, the paper provides an overview of conventional protection practices. This includes network segmentation, firewalls, and DMZs; managing workstations, servers, end-users, and applications; and implementing active defense measures, including security event monitoring and management.
The second part of the paper is devoted to more recent techniques, based on the application of intrinsic cyber security advances that have been applied in military, aerospace, and ecommerce, and are now being used to protect industrial control systems. These create a hardware end-point root of trust that combines advanced cryptography, digital signing techniques, an industrial certificate authority, and public key infrastructure (PKIs) built into the control system to create an infrastructure for user defense.
The paper also presents the features of the Bedrock Open Secure Automation platform, which embraces the best practices discussed and details the process by which they can be applied to legacy and new systems.
The Industrial Internet Consortium (IIC) has been incredibly active over the past month. While I’ve been traveling, news releases and interview opportunities have been pouring in.

Why it’s important:
These news items when viewed collectively show momentum for what is happening with the Industrial Internet—or as some say the Industrial Internet of Things. These technologies are soon to be powerful business drivers for a new age of manufacturing.
Liaison with Avnu Alliance
The Industrial Internet Consortium (IIC) and Avnu Alliance (Avnu) have agreed to a liaison to work together to advance deployment and interoperability of devices with Time Sensitive Networking (TSN) open standards.
Under the agreement, the IIC and Avnu will work together to align efforts to maximize interoperability, portability, security and privacy for the industrial Internet. Joint activities between the IIC and the Avnu will include:
- Identifying and sharing IIoT best practices
- Realizing interoperability by harmonizing architecture and other elements
- Collaborating on standardization
“Both Avnu and the IIC are well aligned to pursue the advancement of the IIoT. An example of this is Avnu’s participation in the IIC TSN testbed where members have an opportunity to try their equipment and software on the testbed infrastructure. This provides the participants with the ability to discover what’s working and what is not and provide feedback that helps speed market adoption,” said Gary Stuebing, IIC liaison to Avnu. “The lessons learned in our TSN testbed fuel the ability of both of our organizations. TSN could open up critical control applications such as robot control, drive control and vision systems.”
“Our liaison agreement and work with the IIC TSN Testbed demonstrates real-world applications and solutions with TSN and helps to accelerate readiness for the market. The testbed stands as a showcase for the value that TSN standards and ecosystem of manufacturing applications and products bring to the market, including the ability for IIoT to incorporate high-performance and latency-sensitive applications,” said Todd Walter, Avnu Alliance Industrial Segment Chair. “Our collaboration with IIC and the work coming out of the TSN Testbed is already having a direct impact on suppliers and manufacturers who see the technology as a value add for their system structure.”
Avnu and IIC are meeting for a TSN Testbed plugfest later this month to evaluate and trial TSN device conformance tests that are being developed as a baseline certification in the industrial market.
Avnu creates comprehensive certification tests and programs to ensure interoperability of networked devices. The foundational technology enables deterministic synchronized networking based on IEEE Audio Video Bridging (AVB) / Time Sensitive Networking (TSN) base standards. The Alliance, in conjunction with other complementary standards bodies and alliances, provides a united network foundation for use in professional AV, automotive, industrial control and consumer segments.

Smart Factory Machine Learning for Predictive Maintenance Testbed
The Industrial Internet Consortium announced the Smart Factory Machine Learning for Predictive Maintenance Testbed. The testbed is led by two companies, Plethora IIoT, a company, designing and developing cutting-edge answers for Industry 4.0, and Xilinx, the leading provider of All Programmable technology.
This innovative testbed explores machine-learning techniques and evaluates algorithmic approaches for time-critical predictive maintenance. This knowledge leads to actionable insight enabling companies to move away from traditional preventative maintenance to predictive maintenance, which minimizes unplanned downtime and optimizes system operation. This would ultimately help manufacturers increase availability, improve energy efficiency and extend the lifespan of high-volume CNC manufacturing production systems.
“Testbeds are the major focus and activity of the IIC and its members. We provide the opportunity for both small and large companies to collaborate and help solve problems that will drive the adoption of IoT applications in many industries”, said IIC Executive Director Dr. Richard Mark Soley. “The smart factory of the future will require advanced analytics, like those this testbed aims to provide, to identify system degradation before system failure. This type of machine learning and predictive maintenance could extend beyond the manufacturing floor to have a broader impact to other industrial applications.”
“Downtime costs some manufacturers as much as $22k per minute. Therefore, unexpected failures are one of the main players in maintenance costs because of their negative impact due to reactive and unplanned maintenance action. Being able to predict system degradation before failure has a strong positive impact on machine availability: increasing productivity and decreasing downtime, breakdowns and maintenance costs,” said Plethora IIoT Team Leader Javier Diaz. “We’re excited to lead this testbed with Xilinx and work alongside some of the leading players in IIoT technologies. This is a unique opportunity to test together machine learning technologies with those involved in the testbed at different development levels starting from the lab through production environments, where a real deployment solution is utilized. As a result, from these experiences, we can significantly reduce the time-to-market of Plethora IIoT solutions oriented to maximize smart factory competitiveness.”
”Xilinx is committed to providing the Industrial IoT industry with our latest All Programmable SoC and MPSoC platforms – ideal for sensor fusion, real-time, high-performance processing, and machine learning from the edge to the cloud,” stated Dan Isaacs, Director of Corporate Strategic Marketing and Market Development for IIoT and Machine Learning at Xilinx. “The combination of these highly configurable capabilities drives the intelligence of the smart factory.”
Additional IIC member companies participating in this testbed are: Bosch, Microsoft, National Instruments, RTI, System View, GlobalSign, Aicas, Thingswise, Titanium Industrial Security, and iVeia. They provide technologies to enable the Smart Factory Machine Learning testbed, including:
