Primary protocol stack having a secondary protocol stack entry point

摘要: A primary multi-layer protocol stack that allows a secondary to communicatively couple into one or more of its layers. End point device circuitry implements both the and stacks. communication application running on end initiates interaction, e.g., session, via radio intermediate Based change in characteristics, for example, an operation is invoked bridge between layers from stack. Such bridging establishes pathway radio. The radios may support same differing protocols. To avoid having fully reestablish at least session parameter carried forward through bridge. have multiple entry points out stacks operate as two half-duplex bridges.
