TeraFlow - Inter-domain

Focuses on the inter-domain deployment of transport network slices, looking at the deployment challenges of Cooperative, Connected and Automated Mobility (CCAM) services over a distributed edge and cloud infrastructure: unified computing, storage, and networking resources management, multi-domain networking and multi-domain belonging to different network operators.

At the infrastructure layer, the scenario comprises several packet and optical transport networks for the metro and the core segments, providing connectivity to the distributed cloud and edge computing infrastructure. CCAM services can be deployed in micro-DCs at the edge nodes (e.g., cell sites, street cabinets, lampposts), small-DCs (e.g., in a central office) for low/moderate-computation capacity and low response time, and core-DCs in the core network for high-computational capacity and moderate response time. 

In this scenario, transport and cloud infrastructures are administratively partitioned into different domains, each controlled by a TeraFlowSDN Controller instance. In addition to selected uplink-heavy and latency-sensitive scenarios, the intention is to focus on Over-the-Air (OTA) software updates, which are software improvements that a car company sends wirelessly to vehicles. These OTA updates need to reach a moving target; thus, we provide an inter-domain scenario for moving connectivity services based on the position of the network elements. Testing and experimentation will be necessary to address the role of the Transport Network Slice and its endpoints regarding the interaction with adjacent access and service edge (SDN) control domains in this inter-domain scenario.
