“…It will not only provoke performance interruptions as encountered by an end-user, but will also lead to deficiencies for computer infrastructure functionalities. Handover module utilizes relevant methods to predict the next coverage state and can use different methods to provide constant services to users like flow redirection or quick live migration of related virtualized resources via SDN [134]. The Virtual Machine (VM) migration acts a critical part in accessing the servers in real time.…”

The Internet of Things (IoT) has become one of the most known terms in present times, reaching new levels and setting a trend in the world. Evidently, it is the future of connectivity which has turned physical objects into intelligent objects. Therefore, there has been a growing curiosity in the IoT field and this leads to the concept of IoT ecosystem. But the contemporary fragmented ecosystem of regulations, technologies, and systems slows IoT deployments. Thus, we consider multi-tiered computational infrastructure which would be feasible to provide services from the nearest possible location of end devices. To mitigate multi-tier infrastructure issues, Software-Defined Networking (SDN) steps in. The journey behind SDN-supported multi-tier computational infrastructure can be understood from this paper's elaborate study. Next, a comparative analysis on dew, roof, fog and cloud is conducted and the impact of internet on these computing paradigms is briefly explained. Then a novel framework termed "SD-DRFC (Software-Defined Dew, Roof, Fog and Cloud computing)" is proposed for today's IoT ecosystem. The role and functionality of each tier of SD-DRFC framework are adequately explained. A use case focused on the SD-DRFC framework is then presented and simulated by utilizing iFogSim simulator. To evaluate the efficiency of the presented SD-DRFC framework, four QoS parameters (Latency, Network Usage, Cost, and Energy Consumption) are considered in this paper. When comparing the simulation results, the presented SD-DRFC framework performs much better than cloud-only implementation. The advantages and suitability of utilizing this proposed framework have been demonstrated by multiple use-cases which range from conceptual visions to existing running systems.

“…Other solutions that are designed to migrate state of virtual machine instances exist. But, they come with a large overhead because they move much more state information than needed to operate a VNF . In addition, more specific approaches that focus on joint traffic steering and state migration of VNFs have been proposed.…”

A flow handover protocol to support state migration in softwarized networks

Summary Softwarized networks are the key enabler for elastic, on‐demand service deployments of virtualized network functions. They allow to dynamically steer traffic through the network when new network functions are instantiated, or old ones are terminated. These scenarios become in particular challenging when stateful functions are involved, necessitating state management solutions to migrate state between the functions. The problem with existing solutions is that they typically embrace state migration and flow rerouting jointly, imposing a huge set of requirements on the on‐boarded virtualized network functions (VNFs), eg, solution‐specific state management interfaces. To change this, we introduce the seamless handover protocol (SHarP). An easy‐to‐use, loss‐less, and order‐preserving flow rerouting mechanism that is not fixed to a single state management approach. Using SHarP, VNF vendors are empowered to implement or use the state management solution of their choice. SHarP supports these solutions with additional information when flows are migrated. In this paper, we present SHarP's design, its open source prototype implementation, and show how SHarP significantly reduces the buffer usage at a central (SDN) controller, which is a typical bottleneck in state‐of‐the‐art solutions. Our experiments show that SHarP uses a constant amount of controller buffer, irrespective of the time taken to migrate the VNF state.

“…OpenFlow (OF) [2], which is the most commonly used protocol to implement SDN, has an upper boundary in its flexibility due to the limited set of configurations specified in the specification of each OF protocol version. In addition to flexibility of flow configuration, SDN's network control can also indirectly support the flexibility of network functions placement [16], flow configuration [17] and topology adaptation [18].…”

Flexibility is often claimed as a competitive advantage when proposing new network designs. However, most proposals provide only qualitative arguments for their improved support of flexibility. Quantitative arguments vary a lot among different proposals. A general understanding for flexibility is not yet clearly defined, leaving it to the reader to draw the right conclusions based on background information. The term flexibility is commonly defined as the ability to adapt to changes. For networks, flexibility would refer to the ability to adapt the available network resources, such as flows or topology, to changes of design requirements, e.g., shorter latency budgets or different traffic distributions. Recent concepts such as Software Defined Networking, Network Virtualization and Network Function Virtualization have emerged claiming to provide more flexibility in networks. Nevertheless, a deeper understanding of what flexibility means and how it could be quantified to compare different network designs remains open. In this paper, we ask whether flexibility can be a new measure for network design space analysis. As it is quite challenging to formulate a flexibility measure that covers all network aspects, we propose an initial set of flexibility aspects to start grounding guidelines. Our initial selection is backed up by an analysis of Software Defined Networking, Network Virtualization and Network Function Virtualization for their support of the selected flexibility aspects. Our research methodology is based on a systematic approach that leads to network design guidelines with respect to flexibility.
