Resumen:
The rise of new types of business models with service providers, content providers, and virtual network operators entering in competition with traditional telco operators is reducing revenue margins, making cost-effective provisioning mechanism a necessity. Costly massive over-provisioning needs thus to be replaced by more intelligent dynamic resource allocation. In addition, it is increasingly recognized that many upcoming 5G applications and services will require assured end-to-end quality of service. Operators have thus started to look at network function virtualization and software-defined networks (SDNs) as means to address the challenges of cost-effective and highly dynamic end-to-end provisioning. In this paper we present a test case of an SDN-driven end-to-end service orchestration using a transport API called the control orchestration protocol. Our testbed, interconnecting a core network (within the Telefonica premises in Madrid) and an access network (within the Trinity College of Dublin facilities), demonstrates the possibility to operate sub-second end-to-end capacity reservation, showcasing SDN provisioning across multi-domain networks.
