Network slicing in 5G and Beyond 5G will require the coordination of RAN, transport network, and mobile core.
For transport network, which is connects each NW domain from the fronthaul to the core, the IETF is currently discussing how to realize slicing using existing technologies such as VPN.
From the perspective of transport network, we believe that it is important to control multiple layers in an integrated way for the centralized management of slices.
This brings us to the discussion of integrated management of multiple layers, i.e., integrated management of IP transport and optical transport.
Optical transmission has traditionally played a major role as just a pipe, and dynamically controlling itself has not been common due to its difficulty, except for restoration switching work.
However, with the recent trends, such as disaggregation and white-boxing of optical transmission systems, as well as the trend of IOWN (All Photonics Network project by NTT), high-speed control of optical transmission layers is becoming necessary and easy nowadays.
In addition, there is a growing momentum for hard isolation slicing that takes advantage of the high capacity, low latency, and low jitter characteristics of optical, and we believe that integrated multi-layer management, including optical as well as conventional IP layer management, will become more important from the perspective of service operation.
Integrated multi-layer management in service provider networks has been attempted by SDN controllers and others, but has not yet been practical use.
In this presentation, I would like to introduce and discuss why multi-layer integrated management system is needed in near future, the reasons why it has not been realized so far, and the roadmap for its realization.
