Rapporteur:  Mr. Groenendijk, Jan

Network slicing is a key feature for the next generation network. It is about transforming the network/system from a static "one size fits all" paradigm, to a new paradigm where logical networks/partitions are created, with appropriate isolation, resources and optimized topology to serve a particular purpose or service category (e.g. use case/traffic category, or for internal reasons) or even individual customers (logical system created "on demand"). It can be enriched by use of NFV and SDN.
The network slicing concept consists of 3 layers:
  1. Service Instance Layer,
  2. Network Slice Instance Layer, and
  3. Resource layer where each layer requires management functions.
The present document investigates and makes recommendations on management and orchestration for network slicing on the Network Slice Instance Layer and for non-virtualised NE's also the Resource layer. Furthermore, the 3GPP role for Service Instance Layer has been investigated. The Resource layer for VNFs is excluded from this study.
