First experimental demonstration of a distributed cloud and heterogeneous network orchestration with a common Transport API for E2E services with QoS

Control Orchestration Protocol: Unified Transport API for Distributed Cloud and Network Orchestration

“…This paper extends the work in [4]. In summary, it presents a detailed description of the Control Orchestration Protocol and the experimental validation of an integrated orchestration of IT and heterogeneous network resources for E2E transport services' provisioning and recovery with QoS.…”

SDN Control and Monitoring of SDM/WDM and Packet Transport Networks for 5G Fronthaul/Backhaul

“…In particular, we propose three child SDN controllers, one for the fronthaul segment, another for the NGF-I segment, and the last for the backhaul segment, and a parent SDN controller on top acting as the Xhaul transport network orchestrator (or controller of controllers). It allows the control (e.g., E2E transport service provisioning, path computation, network topology and resource dissemination), at a higher, abstracted level, of the heterogeneous fronthaul and backhaul network technologies regardless of the specific control plane technology employed in each domain through the use of the Transport API (TAPI) experimentally validated by the authors in [4]. This TAPI has to be properly extended in order to deal with the specific SDM transport technologies that are currently not covered.…”

E2E Transport API demonstration in hierarchical scenarios

“…Therefore, the work in [3] lacked a standard interface to operate the optical domains. Based on this need, the authors in [4] proposed the utilization of the Control Orchestration Protocol (COP), which provides a research-oriented multi-technology approach using YANG/RESTconf [5]. This reseach work was taken as a basis to define the functional requirements of the ONF TAPI [6].…”
