DECOR stands for Dynamic End-to-end Connectivity Orchestration and Routing. It is a concept that aims to provide flexible and efficient network connectivity for telecom services, such as 5G, cloud, and edge computing. DECOR proposes a new architecture that leverages software-defined networking (SDN), network function virtualization (NFV), and network slicing to enable dynamic and on-demand provisioning of end-to-end network paths across multiple domains and technologies.
The primary functions of DECOR are:
- To abstract the network resources and capabilities of different domains and technologies into a unified network view.
- To orchestrate and coordinate the network functions and services across different domains and technologies according to the service requirements and policies.
- To route and optimize the network traffic across different domains and technologies based on the network conditions and performance.
DECOR works by using a hierarchical and modular architecture that consists of three main components:
- The DECOR Service Orchestrator (DSO), which is responsible for managing the end-to-end network connectivity for telecom services, and interacting with the service layer and the network layer.
- The DECOR Domain Orchestrator (DDO), which is responsible for managing the network resources and capabilities within a specific domain, and interacting with the DSO and the network elements.
- The DECOR Network Element (DNE), which is responsible for implementing the network functions and services within a specific network element, and interacting with the DDO and the network infrastructure.
