Scope: The present document describes an information specification of resources used by services in network slices to provide true resource-assured multi-tenancy across multiple administrative and technology domains. It does not@ cover the data plane or hardware aspects of traffic associated with a slice@ nor does it alter the core control plane functionality of physical network infrastructure and domains. Any specific language to describe a network slice is out of scope as well. As such@ the topic of network slices encompasses the combination of virtualization@ cloud centric@ NFV and SDN technologies the primary gap identified is a lack of normalized resource information flow over a plurality of provider administration planes (or domains). Resource requirement of a given network slice can be satisfied in different networks using different technologies; the goal of the present document is to provide a simple manageable and operable network through a common interface while hiding infrastructure complexities. The present document defines how several of those technologies may be used in coordination to offer description and monitoring of services in a network slice. Please note that the scope does not try to formally define a network slice@ instead it relies on background material for the purpose.
