Abstract

   The requirement of slicing network resource with desired quality of
   service is emerging at every network technology, including the
   Optical Transport Networks (OTN). As a part of the transport network,
   the OTN has the capability to provide hard pipes with guaranteed data
   isolation and deterministic low latency, which are highly demanded in
   the Service Level Agreement (SLA).

   This document describes a framework for OTN network slicing. A YANG
   data model augmentation will be defined in a future version of this
   draft.

   isolation and deterministic low latency, which are highly demanded in
   the Service Level Agreement (SLA).

   This document describes a framework for OTN network slicing. A YANG
   data model augmentation will be defined in a future version of this
   draft.

2. Use Cases for OTN Network Slicing

2.1. Leased Line Services with OTN

   For large OTT enterprises, leased lines have the advantage of
   providing high-speed connections with low costs. On the other hand,
