    The correct answer is all of the above. The PSA is the overall architecture, it’s the name of the ‘Modular framework’. It consists of sub-modules which are the NMP and third party MPPs. These have sub-modules which are the SATPs and PSPs. It’s the PSPs (Path selection Policys) that ‘Manage Physical path claiming and unclaiming’.
