2.2 System Architecture AeroMACS Network Overview and Architecture 2.2.1 2.2.1.3.1 This section provides an overview of the AeroMACS network on the Network Reference Model describing the functional blocks and reference points of the Access Service Network (ASN) and Connectivity Service Network (CSN). Secondly, an end-to-end AeroMACS service network architecture is proposed based in the Network Reference Model. 2.2.1.1 AeroMACS Reference Network 2.2.1.1.1 The Network Reference Model (NRM) is a general logical representation of the network architecture, including AeroMACS, based on . The NRM identifies functional entities and the reference points (RP) over which interoperability is achieved between these functional entities. Each of the entities, SS, ASN and CSN represent a grouping of functional entities. A reference point (RP) represents a conceptual link that connects different functions of different functional entities. RPs are not necessarily a physical interface. These functions make use of various protocols associated with an RP. Figure 1 introduces overall interoperability reference points between AeroMACS functional entities. SS, ASN and CSN functions MAY be realized in single physical entities. As an alternative approach: SS, ASN and CSN functions MAY be distributed over multiple physical entities.
