PFP loop data path is sending data from PFP-A back to PFP-A or sending data from PFP-B back to PFP-B as shown in
Figure 12 Microprocessor, Auxiliary and Internal Traffic Detector/Generator Data Path p.38
- Microprocessor data path is sending data from/to microprocessor interface to/from PFP-A.
- Auxiliary data path is sending data from/to Auxiliary interface to/from PFP-B.
- Internal traffic generator / detector data path is sending data from Internal Traffic Generator to PFP-B and from PFP-B to Internal Traffic Detector.
