7.6. P-NNI Signaling Adaptations for Optical Networks

The P-NNI hierarchy, addressing, and peer group identification were discussed in Chapter 5. In the following, we look at P-NNI signaling features and their adaptation for signaling in optical networks. The peer group hierarchy depicted in Figure 5-15 is useful for the discussion below and hence it is reproduced as Figure 7-38.

7.6.1. P-NNI Signaling Communication

The signaling communication protocol model under P-NNI is shown in Figure 7-39. Here, the P-NNI protocol entities in peer nodes utilize a signaling ATM adaptation layer (SAAL) which consists of the following: ...
