Factorization of concerns to build a SDP (service delivery platform)

摘要

A service layer is provided that is concerned with providing a service. Also, a network layer is provided that is concerned with communicating with devices. The concerns of each layer are separate. For example, the service layer performs the service without worrying about any network dependencies. Also, the network layer is concerned with communicating with devices without worrying about the services that are being performed. These layers, however, are configured to work together such that a result of the service layer is used by the network layer. For example, a service may be performed by the service layer and then the result of the service is communicated to a device using the network layer.
