## 3 R-SIN Architecture Model Based on DaaC
### Realization Mechanism  
#### 3.2.1 Recombination Mechanism  
In order to analyze the process of reconstructing the R-SIN architecture model, through combining the content above, we can implement an R-SIN architecture from two angles: the management layer, and the resource layer. The management layer is the management center of the R-SIN, named the R-SIN management center (**RMC**), and the resource layer is the R-SIN resource center (**RRC**). The two complement each other, and jointly complete and realize the task-oriented reorganization of the SIN. The R-SIN framework is as follows; there are three parts, including the RMC, data center (DC), and entity resource pool (ERP), as shown in Figure 4.  
RMC and RRC play decisive roles in the construction of the R-SIN, so we present its operating mechanism graphically, as shown in Figure 5.  
Figure 4: Reorganization SIN (R-SIN) framework. As shown in Figure 5, we give the operation mechanism of the R-SIN, which is mainly implemented between RMC and RRC. The following is a detailed discussion of the RMC operation mechanism and RRC operation mechanism, respectively. (a) RMC operation mechanism  
The RMC acts as the core of the management and control, acting as the brain, which is also the interface for accepting tasks/instructions. After receiving the orders/instructions, it sets the RG according to the demand and the service that is to be provided. Meanwhile, it sends instructions to the RRC, and analyzes the data information that can meet the needs of the target. After the RRC completes the score data, it can send a second instruction to the RRC, and receive reply information. Through combining this information with the identified physical resources, we can make the reorganization scheme (RS) based on the reorganization goal (RG) and send instructions to establish a connection. While receiving feedback instructions for the establishment of an R-SIN, a comparative analysis of the functions and directives/tasks provided by the network is required in order to further optimize and adjust the RS. If there is room for improvement, repeat steps (r) (r) (r) (r) (r) RRC operation mechanism  
The RRC mainly provides data resources and equipment entity resources, and plays the role of the resource base. It has an interface that accepts RMC instructions, and an interface that outputs a reconfigurable network. The DC is formed by bringing together the data of the entities that are contained in the entity resources, and organizing them in an orderly manner. Moreover, it has numbered and detailed data descriptions for all of the entity resources, including attribute information and data for all of the entity resources. In addition, it is the central link between the RMC and the ERP, which acts as a bridge and link. The R-SIN mainly involves the collaboration of the RMC and RRC to achieve service-oriented reorganization. According to the RG, combined with the RS, by analyzing the data resources of the DC, some related resource entities are dispatched from the ERP to eventually generate a SIN that can achieve specific functions and provide the required services. Therefore, we use five tuples to define the reconfigurable model. **Definition 8 (R-SINs Architecture Model, RAM). **_RAM formalization is expressed as:_  
\[M_{RA}=\langle RG,RTS,RD,RE,RS\rangle \tag{1}\]  
_where \(RG\) represents a formal description of what styles and services are built on an R-SIN, which are driven by task requirements. RTS is an abbreviation for the R-SIN topology structure, and RTS represents a formal description of the structure, components, and connections of an R-SIN in order to achieve the RG. The reconfigurable functional resource collection contains a reconfigurable entity (RE) and reconfigurable data
