Higher layer services and information IEs What we already have: TYPE_IE_POA_SUBNET_INFORMATION (per PoA) TYPE_IE_POA_CAPABILITIES (per PoA) Security Available (Y/N) QoS Available (Y/N) Emergency Service Available (Y/N) Others Consensus to increase IE’s utilities were made by Higher Layer IE Adhoc at Denver meeting.
