Research paper thumbnail of General Satisfaction Assessment of Relationship with Stakeholders

European Cooperation

Under entering into relations with the enterprise, they make certain contributions to its activity and wish to receive from such cooperation the desired incentives, which are expressed in satisfying the identified interests of stakeholders. Satisfaction of their interests occurs mainly by means of the enterprise management of the relations with them. That is why, the introduction into activity of stakeholder management is very topical for today’s practice of the enterprise management, the development and implementation of strategies for meeting their interests is a separate trend of stakeholder management. The research paper presents the results of categorization of stakeholders according to the level of their...

In this paper, we study the generalization of this structure by developing the closed form expressions of the generalized structure. Through this, any Farrow structure can be replaced by the Newton structure that is more efficient in terms of complexity. Moreover, the closed form expression of the frequency response of the generalized Newton structure is developed. This expression enables the application of filter optimization methods to build customized Newton structures. We demonstrate how this makes possible the design of optimized Newton structures that offer a reduction in complexity by half compared to their Farrow counterparts, while keeping a similar filtering performance.

The fundamental difference between software-defined networks and traditional networks is in the network architecture itself. In SDN, the data-plane is separated from the control-plane. The former is composed of SDN dummy switches that are directly programmable with flow-based rules by a logically centralized controller that resides at the control plane. SDN has evolved tremendously throughout the last few years. Although the two main approaches, proactive approach and reactive approach, were being widely addressed as a framework of communication between the control-plane and the data-plane, a new hybrid approach is emerging which combines the advantages of the proactive approach, in pre-installing the flow rules in the data-plane, and the advantages of the reactive approach, in its ability to dynamically react to network events. This hybrid approach utilizes the potential of the SDN switches to recognize and host state machines. While the trending success of SDN is set to continue, this evolving network paradigm requires a new set of tools and strategies to secure the network elements against intrusions and at the same time maintain its efficiency and reliability. In this text, we take advantage of the hybrid approach of network controllability and management to offload the processing of stateful applications from the control-plane to the data-plane and propose our framework, Stateful Distributed Firewall as a Service in SDN (SDFS), that optimizes a distributed stateful application in the data-plane to transform the SDN network into a one big firewall. While maintaining modularity of the framework, SDFS offers an optimized processing burden distribution of the stateful application in the data-plane among the switches in the network with inherent fault-tolerance mechanisms that eliminate the need for immediate controller intervention even in cases of failure or attacks on the network.
