Contribution

It proposes a unified SDN architecture for carrier networks that integrates multiple technologies using standardized models and interfaces, facilitating softwarized operations.

Findings

Supports diverse technologies like IP, optics, and microwave links

Enables dynamic and flexible network management

Aligns with standards for future-proof operations

Abstract

Network softwarization will permit the dynamic configuration of the transport infrastructure, in order to facilitate the adaptation needed for future advanced services. However, the promise of full flexibility can only be achieved through proper levels of abstraction and by means of normalized interfaces and service and device models. This paper presents the SDN architecture that is being defined by Telef\'onica for the management and control of its transport networks, including a variety of technologies such as IP, optics and microwave radio links, pursuing a standard-based approach for an effective and future-proof introduction of softwarized operations.
