  3. Encoding RWA Info in WSON • Scopeis the WSON specific aspects of the RWA WSON Framework and Info Model drafts. • 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. 79th IETF – Beijing, China, November 2010

  4. Changes from Encoding 05.txt • In the Resource Block Information Sub-TLV (section 5.1) revised the encoding for the “shared access” indicators to only use one bit each for ingress and egress. 79th IETF – Beijing, China, November 2010
