ITU-T Recommendations

Supplement 74 to ITU-T G-series Recommendations considers the possible implications of network slicing and related functionality (e.g., as defined in 3GPP and IMT-2020 as part of 5G wireless) in the setting of optical access networks, in particular passive optical network (PON) systems. Use cases are identified for slicing with a focus on PON slicing. The Supplement describes the functional expectations of a PON system to support PON slicing and considers the architecture for the control of PON slices. Also, the aim is to provide a clear demarcation of PON slicing such that it can be considered independently of slicing in any other segments of the network.
