This week, service providers, vendors and analysts from around the world will gather in The Netherlands to attend SDN and OpenFlow World Congress, which is taking place in The Hague this time.
Happy Birthday NFV
Those of us that attended this same event back in October 2012, when it was located in Darmstadt, Germany, will remember that as the venue when the Network Functions Virtualization (NFV) initiative was first announced following months of discussions between been several leading service providers.
So we can view this week as NFV’s fourth birthday. Undoubtedly, one of the key discussion topics at this year’s event will be the level of progress that the telecom industry has made in its adoption of NFV.
In this post, we’ll take a brief look at one of the key challenges that our industry has faced over the past four years, namely how to ensure the multi-vendor interoperability that is so important to service providers as they look to avoid vendor lock-in and accelerate their deployment of new services. At Wind River, we’ve built up a lot of expertise in this area and we’ll share some key learnings from working on projects with a wide range of partners.
Open Standards Avoid Vendor Lock-In
When the NFV initiative first started, the ETSI organization assumed the responsibility for developing the open standards that would define the complete software architecture at multiple levels. ETSI continues to do a tremendous amount of invaluable work and, more recently, the Open Platform for NFV (OPNFV) project has made good progress in releasing open-source implementations of the NFV Infrastructure (NFVI) layer.
From the service providers' perspective, open standards mitigate the risk of vendor lock-on by encouraging the development of compatible and interoperable products by multiple companies.
A multi-vendor approach allows service providers to leverage the best available solutions at each level of the architecture, rather than being constrained by monolithic single-vendor products. They can rapidly adopt new or better solutions as soon as they become available, avoiding the limitations imposed by long release cycles for proprietary, vertically integrated products. This results in new business opportunities for innovative software companies and indeed the telecom market is now open to companies with pure software expertise rather than restricted to vendors who can offer integrated hardware-plus-software solutions.
While all these business advantages encourage service providers to incorporate products from more than one vendor in the complete solution that they deploy, they need proof that products that should work together seamlessly actually do so. For vendors like Wind River, ensuring compatibility with open standards means more than designing our products to meet the ETSI standards: it’s also critical for us to demonstrate interoperability with other companies in the NFV ecosystem.
Titanium Cloud Brings Interoperable Solutions
At Wind River, this compelling need for interoperability was a key element of our strategy as we introduced the original Titanium Server network virtualization 
platform back in 2014, when NFV was still a toddler, and as we followed up with Titanium Server CPE earlier this year.
Despite the compelling advantages that Titanium Server provides in terms of service uptime, operational cost reductions and performance, we recognized that service providers would deploy it as an element of a complete, end-to-end solution for a specific use case. We knew that they would expect seamless interoperability and compatibility between all the individual elements of that solution.
So in 2014 we also launched the Titanium Cloud ecosystem, through which we work closely with our partners at an engineering level to make sure that their products work correctly with Titanium Server.
Besides ensuring interoperability, our experts also ensure that our partners leverage whatever Titanium Server optimizations are appropriate to ensure maximum service uptime and maximum performance.
Reflecting the end-to-end NFV architecture outlined by ETSI, we determined that the Titanium Cloud ecosystem should comprise four categories of partners. With Titanium Server as the baseline NVF Infrastructure (NFVI) software platform, we would validate partner products in the categories of OSS/BSS solutions, service orchestrators, Virtual Network Functions (VNFs) and hardware infrastructure.
The growth of the Titanium Cloud ecosystem reflects the importance of proven, multi-vendor solutions to the decisions that service providers are making.
When we launched Titanium Cloud, we did so with five founder members of the ecosystem, who shared our vision of the importance of such collaboration. By the time of SDN and OpenFlow Congress one year ago, in October 2015, the program already had 23 member companies. Today, we’re proud that 37 companies have joined with us to ensure that we can work together to provide validated end-to-end solutions that accelerate our customers’ NFV deployments while minimizing their schedule risk.
In just the past few days, companies like Advantech, Lanner, RIFT.io, Silver Peak and Versa Networks have all announced their participation in Titanium Cloud. We welcome them as new partners and look forward to collaborating with them to provide service providers with additional examples of proven end-to-end solutions and leading-edge applications.
No Short Cuts To Interoperability
At first glance, the task of validating interoperability between individual vendors’ products looks straightforward. If you believe some of the first PowerPoint presentations espousing the overall NFV architecture, then all we have to do is develop our products in compliance with a stable set of well-documented, comprehensive APIs and we can have high confidence that everything will work together seamlessly.
Of course, that’s not how the world of software works.
In the case of the ETSI architecture, the standards documents don’t fully define many of the interfaces. The API specifications are not interpreted consistently by vendors and are still subject to change. The complexity of the architecture means that vendors frequently have conflicting assumptions that lead to contention for key control points, such as OpenStack Neutron plug-ins. In most cases, comprehensive test frameworks not yet available, though the OPNFV project is doing promising work in this area.
Finally, since we’re talking about a software architecture here, there are dependencies on specific revisions of drivers, kernels and other subsystems, with millions of combinations leading to inevitable issues whenever a single element is updated. There’s no way to guarantee interoperability or compatibility by design.
Given the nascent stage of the NFV industry and relative immaturity of most vendors’ products, the only sensible approach to guaranteeing interoperability at this point is a case-by-case validation of the product combinations that service providers will deploy.
Call In The Experts
The validation process is a fundamental benefit that the Titanium Cloud brings to Wind River, to our partners and to the customers deploying multi-vendor solutions. So we don’t take any shortcuts and we focus on ensuring high-quality results that will genuinely accelerate our customers’ own testing and deployment cycles.
We’ve learned that partner product validations are complex technical programs that require engineering commitments on both sides. In our case, we have a technical team that’s dedicated to this task and that has now amassed a wealth of experience through working with partners that span all four categories of our ecosystem.
There are no substitutes for comprehensive test plans, detailed documentation and rigorous reports that capture the results of validations. While these collaterals are obviously essential to us and to our partners, we’ve found that they’re also of great interest to our mutual customers, who inevitably want to know exactly what we mean when we tell them that a specific product has been validated with Titanium Server.
We’ve also discovered an unexpected benefit of all this validation testing: in many cases, our partners are excellent beta sites for us. Often, the nature of their testing means that they’re stressing Titanium Server harder, earlier and in different ways than our direct customers. They’re fully leveraging the features and performance optimizations that we provide, so that they can deliver the best possible results from their own applications, orchestrators or hardware platforms.
During the Intel Network Builders Summit that precedes this week’s SDN and OpenFlow World Congress, my colleague Jeff Gowan described these validation challenges and solutions in detail during a presentation titled “Titanium Cloud: Better Together”. For anyone unable to attend Jeff’s talk, it’s well worth downloading the slides for an interesting read on this topic.
Looking Ahead
Over the two years since we launched Titanium Cloud, we’ve demonstrated that an ecosystem based around the comprehensive validation of partner products delivers massive business benefits for us, for our partners and for our mutual customers. With service providers looking for proven end-to-end solutions rather than point products, Titanium Cloud accelerates their NFV deployments and minimizes their schedule risk.
The number of industry-leading hardware and software companies participating in this ecosystem shows that they also realize the benefits of this kind of cooperation. We’re very grateful for all the hard work that’s being done by our current partners and we look forward to collaborating with additional companies in the future.

Monitoring and Securing the Smart Grid
Phasor measurement unit (PMUs) play a critical role in the smart grid, helping utilities dynamically assess and manage the performance of independently operated grid systems. By keeping different parts of the grid in sync, PMUs ensure that consumers get reliable delivery of electricity, at the lowest overall cost to the consumer and the service provider.
PMUs measure the magnitude and phase angle of alternating current (AC) using a common time source, such as the global positioning system (GPS). These time-tagged measurements, or phasors, give utilities a synchronized view of performance across the grid (Figure 1). When multiple phasors are taken at the same time, they are collectively called synchrophasors.
Figure 1. A phasor measurement unit (PMU) gathers and processes the data on voltage magnitude and phase angle from powerline sensors.
To gather and analyze this data effectively, utilities need to have data acquisition, processing, and visualization, all working seamlessly across platforms and systems. To meet these demands, National Instruments (NI), Hewlett Packard Enterprise (HPE), and OSIsoft used the Intel® IoT Platform as the foundation for a “best of breed” PMU.
This smart, connected PMU builds on the interoperability, connectivity, security, scalability, and manageability features of the IntelIoT Platform. It comes with open code that lets grid owners get deeper and faster insight into problems, so they can optimize transmission and distribution (T&D).
Configurable, high-performance data acquisition
The heart of the PMU is the customizable NI cRIO-9038 CompactRIO Platform. This platform can be programmed to have many personalities, such as power quality assurance, smart switch, or recloser. In this instance, it is set up as a PMU that can be located at any point in the grid, including on top of power poles or at substations.
A fundamental feature of the CompactRIO Platform is its combination of a processor for control and analysis, and an FPGA for hardware-based data processing. Specifically, the cRIO-09038 uses an Intel® Atom™ processor E3825 with the performance to run complex algorithms and control routines, and a Xilinx Kintex-7 160T FPGA with the configurability to keep up with changing standards and protocols.
Using the cRIO platform, processor and I/O modules can be exchanged as needed, giving designers an upgrade path as data gathering and processing requirements increase. In this case, the cRIO-09038 comes equipped with gigabit Ethernet interfaces, USB support, serial ports, and an operating temperature range of -40˚C to 70˚C to handle extreme environments. The whole system is programmed using NI’s high-level LabVIEW graphical system design software.
Moving in from the edge, the PMU data is passed to centralized servers powered by HPE Proliant DL380 Gen9 servers (Figure 2). The latest versions of these servers feature Intel® Xeon® processor E5-2600 v4 with 2500-MHz DDR4 memory to accelerate time to insight. These servers function as phasor data concentrators (PDCs) and are rack mountable so they can scale to handle as many PMUs as needed.
Figure 2. Hewlett Packard Enterprise Proliant DL380 accelerates time to insight.
The final stage in the synchrophasor solution is data analytics and visualization. This is the role of OSIsoft PI System, a highly secure, NERC CIP-qualified system that integrates and correlates the data with traditional operational electric grid information (Figure 3). It complies with C36.118, the IEEE standard for the measurement of synchronized phasors of power-system current and voltages. In effect, the PI System’s visualization and analytics help utilities fully understand what’s going on with their grid network, while its early-warning system helps operators react to problems quickly.
Figure 3. OSIsoft Pi System provides utility engineers and operators a variety of ways to analyze and optimize their grids. (Source: Intel)
A clear vision for the smart grid
As the smart grid continues to expand, designers are being asked to help utilities face challenges such as the distribution of renewable energy, changing load requirements, more regulations, lower cost, scalability, reliable communications, security, and fast and accurate analysis for improved operator response times.
These requirements call for smart PMUs like the one built by NI, HPE, and OSI. Their synchrophasor is end-to-end, high-capacity, validated and tested, remotely managed, and cost-effective via standards-based components. This improves service and reduces overall cost.
And of course this is only one way you can start building a smarter grid. To see more design solutions, take a look at the Solutions Directory.

Creating an Internet of Things (IoT) backbone for smart city and smart building solutions is a lot of work. It requires a secure and scalable solution with all the necessary connectivity options for connecting legacy equipment to the cloud. It requires software for managing devices, collecting and analyzing their data, displaying results, automating functions, and delivering new services. In addition, there needs to be a high level API with access to normalized data so that application developers can use the infrastructure to deliver value-added applications at reduced time and cost.
Developers can significantly shorten time to market by basing solutions on open, scalable IoT frameworks. These frameworks can provide end-to-end solution templates, along with the required gateways, for IoT applications. Templates include the necessary software and configuration required to collect, store, and analyze data, as well as manage the equipment in the field. All that an OEM or system integrator needs to do to make the product theirs is fine tune the configuration to fit their respective use case.
A good example of such a framework comes from Shaspa, a company that specializes in end-to-end IoT solutions for cities and commercial buildings (such as retail, hotel, or office building). Their modular, fully scalable Shaspa Bridge and Shaspa Service Delivery Framework meets the requirements of any size project, from a single building to millions of units. OEMs and system integrators can choose to go with Shaspa’s pre-configured solutions featuring components from Intel, Wind River, Dell, and IBM, or they can select what they need from the Framework to meet unique requirements.
Let’s look at how this all comes together.
Bridging the Gap with an IoT Gateway
Shaspa IoT solutions start with a versatile device – the Shaspa Bridge. Based on the Intel® IoT Gateway design, this unit provides the basic building block for connecting and controlling building automation systems, household appliances, and mobile environments (Figure 1).
Figure 1. The Shaspa Bridge is based on the Intel® IoT Gateway reference design.
The Shaspa Bridge can operate in two modes: standalone or fully automated Service Gateway. Standalone mode provides a local solution for connecting, monitoring, and automating equipment functions in a commercial building. In Gateway mode, the Shaspa Bridge acts as a local extension to the cloud-based Service Delivery Framework.
The unit supports the most commonly found protocols in building automation systems, including. ZigBee, ZWave, KNX, Modbus, Enocean, Modbus, Profibus, and LON. By connecting with existing building controls and supporting more than 100,000 devices, the Shaspa Bridge protects investments made in legacy systems or appliances, as well as enables the addition of new devices from diverse vendors. A partner can pick from over 100 industry-specific applications – from simple sub-metering and demand-based control to complex video analytics for retail solutions – to build customer applications. The Shaspa Bridge also updates easily with new applications as protocols and systems emerge.
The Shaspa Bridge is available with a range of available templates to reduce time to market and comply with industry best practices. It can be centrally managed (except in standalone mode) to reduce the time and costs of updates to firmware, applications, and defined data streams. Developers can also order the Shaspa Bridge with simple applications, then add applications on demand through the Shaspa Applications Store.
Empowering Apps with the Service Delivery Framework
The Shaspa Service Delivery Framework is a robust, secure, highly scalable cloud-based software platform (Figure 2). The Framework collects, stores and analyzes data, as well as automates functions, using information from the Shaspa Bridge and other sources.
Figure 2. The Shaspa Service Delivery Framework is a robust and scalable cloud-based software solution.
The Service Delivery Framework enables smart device management, cross gateway interconnectivity, and control of application deployment with secure data processing through a cloud-based service delivery platform. The platform allows rapid introduction of services and the ability to scale up rapidly.
Using Shaspa’s included Application Service Framework, manufacturers and service providers can cooperate, collaborate and design new products connected to services. Typical applications are smart home solutions, home energy management systems, social energy meters, green datacenters, assisted living, e-mobility, and carbon management solutions. The Application Service Framework also enables technology for device management and service.
The Shaspa Service Delivery Framework is available with valuable tools such as IBM* Informix*, IBM Messagesight, IBM Cognos, Dell Statistica, and SAP PM. These tools provide analytics, delivering valuable insights for improving efficiency and forming the basis for new services as your solution amasses data.
The Smart Delivery Framework also makes it easier to achieve greater efficiency. It enables management of all asset types – traditional IT, physical, and emerging smart assets – on a single platform. Running solutions like the IBM Maximo® Asset and Service Management or SAP PM on the Smart Delivery Framework yields a comprehensive view of all asset types. Combining information from devices connected to the Shaspa Gateway with information available in the Shaspa cloud allows more precise measures to be taken to assure maximum availability and performance of devices.
A Versatile IoT Solution
A key to the versatility of the Shaspa Service Delivery Framework is the scalability of the Intel IoT Gateway design (Figure 3). Intel IoT Gateway reference designs range from the Intel® Quark™ SoC for headless applications all the way up to powerful 6th generation Intel® Core™ processors that can run high performance local analytics applications that reduce network traffic and cloud costs.
Figure 3. The scalability of the Intel® IoT Gateway reference design enables the Shaspa Bridge to address a wide range of usage models.
For applications requiring smart metering, demand response, and smart automation, the Shaspa Bridge comes with a range of Intel Quark SoCs designed to meet various environmental situations. Software includes McAfee* Embedded Control, Wind River* Linux* and Wind River Helix* Device Cloud.
When more local processing or filtering is required, Shaspa offers the Dell Edge Gateway 5000 series based on the Intel® Atom™ processor E3800 product family. These processors utilize Intel’s 22nm process technology with 3-D tri-gate transistors. The processors deliver excellent compute performance and Intel® HD graphics for small form factors such as gateways. A thermal design power (TDP) envelope of 5W to 10W makes this processor family an ideal cost- and energy-saving solution for embedded environments.

Hi all,
We have a platform as shown below:
Now we run RFC2544 throughput test for Linux native ip forwarding, and get the result as show below:
Focus on 1518B, the throughput is totally 100%.
However, we run RFC2544 test with DPDK (testpmd), and here is the result.
(My command is: #./testpmd -c 0x3 -n 1 -- -i --nb-cores=1 --nb-ports=2 --total-num-mbufs=2048)
The throughput of 1518B is just only 99.297%,
which means it is failed when running 100% offered loading because there is a few frame loss (~0.5%).
Could anyone help us to explain the phenomenon?
Could anyone help us to improve it to 100%?
BTW, we have been search this issue, and I found this post
I just attempted to modify these parameters like rxd, txd, txwt, burst, etc,.. but it doesn't seem work to me.
