Blockchain-based Optical Network Slice Rental Approach for IoT

With the increasing application of the IoT, more and more scenarios need to establish efficient and stable dedicated communication networks. In the 5G era, communication network operators can lease customized optical network slices to users, to meet users' different needs in the application scenarios of the IoT. However, in the multi-user transaction process of optical network slicing, there will be untrusted mechanisms and important data security issues. This paper uses blockchain technology to ensure the optical network slicing lease transaction environment, so that users can complete slicing transactions more safely and build a high-quality dedicated communication network for IoT application scenarios.
