"resource block". A resource block may contain one or more "resource block". A resource block may contain one or more
resources. As resource blocks are the smallest identifiable unit of resources. As resource blocks are the smallest identifiable unit of
processing resource, one should group together resources into blocks processing resource, one should group together resources into blocks

This document defines the following sub-TLVs pertaining to resources This document defines the following sub-TLVs pertaining to resources
within an optical node: within an optical node:

Each of these sub-TLVs works with one or more sets of resources Each of these sub-TLVs works with one or more sets of resources
rather than just a single resource block. This motivates the rather than just a single resource block. This motivates the
