Tactile Internet Key Enablers
Tara A li -Y ahiya · 2021
As a step forward to realizing the Tactile Internet (TI), this chapter discusses the TI-driven technologies that impact the haptic applications and services from the perspective of end-to-end communication architecture. A key enabler of the TI is the 5G mobile network, considering that the legacy generations of mobile networks cannot meet the rigorous requirements of Quality of Service of mission-critical haptic applications. Network slicing is an effective method to optimize the resources in 5G by creating a virtual environment with the elements needed by any application. The logical network is instantiated through powerful techniques of virtualization, not only for the resources but also for the network functionalities related to these resources, and this is done by network function virtualization (NFV). Software defined networking, NFV and network slicing are practical solutions that aid in the automation of the TI architecture while taking into consideration the specific need of each use case, defined by IEEE 1918.1.
