OMA Technical Plenary Chair Address – Francesco Vadalà
Welcome to the second quarterly newsletter of 2015. To keep up with user base and network growth and in order to satisfy needs of their customers, several operators are changing their approach to network architecture from buying off-the-shelf platforms from incumbent vendors, to using low-cost “commodity” hardware and relying on software to manage the set of functions the network has to perform. This allows new, lower-cost and disruptive entrants to enter the ecosystem, which is good for the broader telco community. When the specifications become open source, any hardware maker can come to an operator with an offer to supply the platforms/nodes. This point about open source software and virtualization is a most interesting item that is happening in the telco system, as initiatives like OPNFV are illustrating. OPNFV is a carrier-grade, integrated, open source platform to accelerate the introduction of new NFV products and services. As an open source project, OPNFV is uniquely positioned to bring together the work of standards bodies, open source communities and commercial suppliers to deliver a de facto standard open source NFV platform for the industry.
Here in OMA we are working to be part of the game on this topic too, and we are developing the white paper “Service Enabler Virtualization” that will provide useful input and motivation for OMA to establish a relationship with these open source projects, similar to their developing relationship with other SDOs/SSOs and the “upstream” open source projects that initiatives such as OPNFV depend upon. I invite you to keep abreast of these activities, as they will determine much of the standardization work to be done here at OMA and across the telco community.
GotAPI – Enabling Interoperability, Security and Development Time and Cost Reduction for IoT Devices
Bryan Sullivan, Board Vice-chair, OMA
Takafumi Yamazoe, NTT DOCOMO
The advent of the Internet of Things (IoT) and associated machine-to-machine (M2M) technologies offers unprecedented opportunity to enhance the way we live, work and play. From healthcare to automotive to public utilities, there is almost no aspect of life that will not be touched by IoT. According to the 2015 Cisco(R) Visual Networking Index(TM) (VNI) Forecast, the number of IP-connected personal devices and M2M connections online will grow to more than 24 billion by 2019. However, in order to realise the potential benefit of IoT, there are business, technology and privacy hurdles that must be addressed and overcome.
The first challenge to be addressed is fragmentation. Increasingly, many types of devices and sensors need to connect to our smartphones, our cars or our home gateways. Smart watches and personal healthcare devices will need to connect to our smartphone, appliances to our home gateway and many of these will connect to our car. Today, developers of each of these sensors and devices must customize their development to each operating system such as iOS or Android. Additionally, similar features from different device manufacturers require different application programming. This can hurt time to market or even consistent functionality across various operating systems, while also driving up development costs.
What’s more, today there is no way for web-based applications running in a browser to work with external devices such as a smart watch. And native applications provided on your device require Software Development Kits (SDKs) that are different for each device. Again this drives up technical complexity, cost and time to market.
A third challenge involves the use of cloud-based servers to manage these devices and act as the interface between the device and the smartphone. Cloud-based data storage, while extremely useful and necessary for many applications, can compromise application speed, as well as add cost and personal data security risk for smaller personal networks.
In order to address these issues, the Open Mobile Alliance (OMA) has developed the OMA Generic Open Terminal API Framework (GotAPI) Version 1.0. GotAPI provides a secure framework for smartphone web applications to access external devices and internal apps through Web-standard technologies supported by major web browsers and smartphone platforms. This allows developers to create applications compatible with a variety of devices, which until now have required dedicated native code development efforts. With GotAPI, applications running in browsers can access external devices consistently across any OS, giving developers the opportunity to help create a new ecosystem of interoperable devices and applications. This open architecture allows developers to write less complex applications for smart devices while expanding market reach.
GotAPI enables application development independent of any particular OS via web technologies such as HTTP (REST), WebSockets, Server-sent Events and WebRTC for Web-based, native and hybrid applications. GotAPI bridges applications and external devices through a standardized framework for APIs, providing for registration, discovery, access, security and authentication, so that these functions no longer have to be implemented independently for each external device, eliminating costly development time and effort. GotAPI Plug-Ins implement the host-device-internal Web APIs exposing services from external devices to applications through GotAPI. Data privacy and confidentiality is maintained and application speed is optimized, because data is not going through other companies’ cloud-based servers.
Many companies have contributed to the development of GotAPI including NTT DOCOMO who contributed their Device Connect WebAPI as the basis for OMA GotAPI. In April of 2015, the Device Web API Consortium was created to promote the use of GotAPI for IoT and wearable devices. To date more than 60 companies have joined this effort including NTT DOCOMO, Softbank and KDDI. There is already a Device Web API Manager supporting GotAPI available for download from Google Play at https://play.google.com/store/apps/details?id=org.deviceconnect.android.manager.
It is the hope of OMA and the Device Web API Consortium that the GotAPI community will continue to grow. NTT DOCOMO’s open-source software project at GitHub already supports various devices through their Plug-Ins with device WebAPIs, which are available at https://github.com/DeviceConnect. Additionally, healthcare device WebAPIs are being developed at OMA. Given these efforts are already underway, we can look forward to a variety of devices coming to market that can connect to our smartphones, cars and gateways to enhance our lives in an open, secure, and cost-effective manner.
