Researchers in South Korea have developed very fast information processing technologies which will help usher in the next generation of the internet. researchers at the electronics and Telecommunications Research Institute (ETRI) in South Korea have developed technology capable of sending packets of digital information at twenty five Gb/s (gigabits per second) – ten times faster than currently available speeds. This technology named TIC-TOC is a critical component of the future Tactile internet, in which information is sent and received at speeds on par with human perception.
This technology operates at a speed fast enough to download a three GB movie within one second. furthermore, the TIC-TOC system enables more urgent data to jump ahead of other info packets and be transferred in one millisecond (1/1000 of a second), the same speed at that the human sense of touch works.
TIC-TOC is stands for Time Controlled Tactile Optical Access and is designed to work on 5G networks. The researchers anticipate the TIC-TOC technology will facilitate advance virtual reality and augmented reality in many sectors, from education and health care to entertainment and public safety.
For example, it can be possible to deploy and operate robots in dangerous or disaster areas with instant sight and feel communication between human controllers and machines. when the machine sees something, the humans sees it, and when the human remotely controls the robot’s hand or head, the motion can happen immediately. the same can be true for telesurgery, with a doctor remotely controlling a robot performing the surgery, but the doctor feels as if she were in the operating room because the response is instantaneous.
The Tactile internet is expected to be the 4th industrial revolution, said HwanSeok Chung, a project leader at ETRI. We can see robots, cars and all other machines connected to the internet all around us. Tactile internet will help humans and machines to interact with each other even from far away.
The team developed TIC-TOC in order to help address the traffic jams that happens within current information processing systems, causing delays. By increasing the speed at that information can be transmitted, and allowing more important info to jump the queue, they have ensured that as soon as a user clicks on a web page, it loads instantly, or they’ll watch a video live essentially without any delay.
Described in the Journal of Lightwave Technology, the TIC-TOC technology consists of internet access control chips and optical transceivers to speed up processing time. Optical Transceiver converts Electrical data into optical signals to transmit over optical fibers. The chips guarantee latency (the time from data’s origin to destination) is less than one millisecond with ETRI’s new low latency oriented packet scheduling technology controlling network traffic. The chips could further increase network speeds faster than twenty five Gb/s by combining several channels for data transmission.
A few hurdles remain before commercialization, like system implementation. ETRI continues researching to resolve such hurdles, and anticipates the tactile internet enabled by TIC-TOC will be accessible within a year.
