However, there are few solutions for the transport of sepsis data with Quality of Service (QoS). In this paper we propose a self-manageable architecture for the provision and delivery of sepsis data using Software-Defined Networking (SDN). To evaluate our proposal, we conducted our experiments in the laboratory. The results are promising because our solution with SDN is able to improve performance, ensure QoS and prioritize sepsis flows, when compared to TCP/IP architectures.

In view of that, we propose an autonomous architecture of service provision and delivery that is QoE aware. The proposed components were designed and validated in a Software-Defined Networking environment. The results demonstrate that the solution is able to collect and infer the user's experience; map the QoS parameters in QoE to predict the Mean Opinion Score, and act autonomously to adjust the resources in the underlying network infrastructure, avoiding degradation of QoE.

For this purpose, we conceived an engine called PAS Engine (Proactive Automatic Semantic Engine). The proposal learns the current user’s experience in the use of a service and acts proactively. It aims to avoid degradation of QoE (Quality of Experience) through the utilization of auxiliary data stored in a Knowledge Base (KB). Such context data are used to assess compliance with a Service Level Agreement (SLA), besides supporting management actions with resources in a SoftwareDefined Networking environment with MAPE-K Control Loop functionality. The experiment results indicated that, by acting proactively, it was possible to take better advantage of network resources and significantly reduce the packet loss rate.

In this paper we propose a network application (Autonomic QoS Broker) and a controller module that implements the OpenVSwitch Database Management Protocol (OVSDB). These two components were implemented and validated in order to provide QoS management with queue prioritization in a SDN environment. Through the experiments, we verified that the resources were provided with differentiation, according to the context of the Knowledge Base. The Broker was successfully able to manage the flows, increasing their bandwidth when possible and changing flows' paths when the links were congested or with latency issues.
