Encoding RWA Info in WSON
• Scope is the WSON specific aspects of the RWA WSON Framework and Info Model drafts. (scope reduction)
• This document provides efficient, protocol-agnostic encodings for the WSON specific information elements. It is intended that protocol-specific documents will reference this memo to describe how information is carried for specific uses.

Changes from Encoding 03.txt
• Removed encodings for general concepts to [Gen-Encode].• Generalized & Simplified Resource Pool
– Use “Resource block” terminology to refer to either wavelength converters, regenerators, or other processing
– “Resource blocks” can contain multiple identical resources better for encoding OEO switches, regular regenerators.
• Added in WSON signal compatibility and processing capability information encodings from ietf-ccamp-signal-compatibility-ospf-00.– Resource block info sub-TLV– Related sub-sub-TLVs: Input Modulation, Input FEC, Input Bit
