Next Generation Protocols (NGP); E2E Network Slicing Reference Framework and Information Model
|Publication Date:||1 September 2018|
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.
