3. 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.
