Title: Trigger Transport concepts
Date Submitted: July,
Presented at IEEE session #03 in Portland

Abstract: Triggers should be primarily independent of media type and protocol transport encapsulation. Some cases may require certain fields to be media or protocol transport specific. Bindings can enable the separation of functions. xx

3. Media independence requirements
Triggers should be independent of bearer (media) type
Triggers shall be defined so they are transportable across all bearer types
Each trigger shall be defined as unique and distinguishable regardless of bearer
Some media types may have media specific, unique capabilities that need to be represented to facilitate mobility
Creation of media specific triggers is discouraged xx

4. Protocol transport independence requirements
Triggers shall be independent of transport type
Triggers shall be transportable by L2 or L3 framing / encapsulation. Not all bearer types support both L2 and L3 encapsulation.
Triggers shall be defined independently from protocol transport fragmentation. Fragmentation/reassembly of triggers may occur.
Triggers shall be defined independent of encryption
Triggers shall be defined independent of integrity protection xx
