8 title: Trace, Profiling and Diagnostics Aggregator - TPDA
17 There is no strict binding between TPDM and TPDA. TPDA can have multiple
18 TPDMs connect to it. But There must be only one TPDA in the path from the
19 TPDM source to TMC sink. TPDM can directly connect to TPDA's inport or
20 connect to funnel which will connect to TPDA's inport.
