Tokyo, January 2014 - Nippon Telegraph and Telephone Corporation (NTT; TSE: 9432, NYSE: NTT) today revealed the “Edge computing” concept which can reduce the cloud application response time by factor of 100 at most, and demonstrated its first research outcome, the “Edge accelerated Web platform” prototype. The research and development effort leading up to the announcement has been carried out as a part of the company’s strategic plan, “Accelerating Innovation and Collaboration for the Next Stage”*1, and is expected to open up a new era of applications for “Smart Life and Smart Work”.
Although cloud services and their use by devices such as smartphones has become quite the norm today, they are increasingly and inevitably facing the problems of poor scalability and slow response time due to their dependence on sole remote servers that may be located far away, possibly across an ocean and on the other side of the planet. Because of the finite speed of light, it takes several hundred milliseconds to interact over the Pacific Ocean, for example. These problems hinder the most promising applications to be widely deployed, such as intelligent transport control systems (ITS) and games that necessitate real-time response time, and the M2M services that will impose huge data traffic loads on the data center.
The edge computing platform solves the problems by the simple idea of locating small servers called edges servers in the vicinity of the users and devices and passing to the servers some of the load of center servers and/or user’s devices. The following benefits are expected (Figure 1).
As a result, the edge computing platform makes it possible to implement new and attractive applications that require real-time responses along with regional M2M/big data transactions, as shown in Figure 2. Typical applications that have the former requirement include ITS or AR and those that have the latter requirement include smart buildings/houses and city management.
The image of applications that can be realized by edge computing platform is shown in Figure 3. Through the spread of the edge computing platform, we will accelerate collaboration with ICT partners and aim at activating the market for new applications.
As the first instance that realizes the edge computing concept, we have developed the “edge accelerated Web platform (EAWP)”; it enables Web applications to run on edge severs. EAWP is a Web application execution framework that takes full advantage of the features of the edge computing. This platform relieves the user’s device from having to process the entire Web application by distributing processing loads to the edge server close to the users and devices. In consideration of the background that Web applications and their developers are rapidly increasing, our development of this platform allows Edge computing developers to use HTML standards to develop high performance applications.
The following are the key features of EAWP (Figure 4).
We will aim at business development from 2014 in Japan toward the realization of our vision. In addition, we will explore new applications, and extend the edge computing platform. In parallel, we will establish the edge computing market at the global level by forming alliances with network carriers, content providers, cloud business, etc.
