Conventional routing protocols such as BGP and OSPF are mature paradigm for dealing inter-domain internet routing. However, distributed nature of these protocols creates scalability, security and policy enforcement issues in Autonomous Systems. Software Defined Networks (SDN), new emerging networking concept, is seen as a solution of existing issues. In SDNs, network core is now being thought as composed of two separate planes: the control plane and the data plane. In SDN, routing is a generally implemented on the control plane in a centralized way. Information are exchanged between centralized controller and distributed data path for the calculation of routing paths and taking routing decision on the base of shared information. In this paper, we focus on the commonly used strategies for routing in SDN, in addition, we also discuss their implication in today's network

“…In brief, the new challenges in this scenario now we face are: 1) we need to protect the private information hidden in the configurations of these outsourced middleboxes; 2) we need to allow the cloud provider to perform the network functionalities without mistakes ( or with acceptable errors). Note that in line with existing outsourcing architecture in SDN [1], [6], [8], we assume that the cloud provider for an enterprise is its Internet Service Providers (ISP), so we will not consider the protection of the packet flows of the enterprise here.…”

Since the advent of software defined networks (SDN), there have been many attempts to outsource the complex and costly local network functionality, i.e. the middlebox, to the cloud in the same way as outsourcing computation and storage. The privacy issues, however, may thwart the enterprises' willingness to adopt this innovation since the underlying configurations of these middleboxes may leak crucial and confidential information which can be utilized by attackers. To address this new problem, we use firewall as an sample functionality and propose the first privacy preserving outsourcing framework and schemes in SDN. The basic technique that we exploit is a groundbreaking tool in cryptography, the cryptographic multilinear map. In contrast to the infeasibility in efficiency if a naive approach is adopted, we devise practical schemes that can outsource the middlebox as a blackbox after obfuscating it such that the cloud provider can efficiently perform the same functionality without knowing its underlying private configurations. Both theoretical analysis and experiments on real-world firewall rules demonstrate that our schemes are secure, accurate, and practical.

Plasma nitriding treatment of 17‐4 precipitation hardening stainless steels was carried out at 400 °C and 450 °C using a direct current unit. The nitriding layer thicknesses of the plasma nitrided at 400 °C and 450 °C were measured as 37.29 μm and 49.97 μm, respectively. The plasma nitrided sample at 400 °C presented dominant martensite and retained austenite phases; however, the height of main martensite diffraction peaks increased at 450 °C. The hardness results demonstrated that the samples at 400 °C and 450 °C were 2.9 and 3.1 times as hard as the untreated sample, respectively. The wear rate values of the sample at 450 °C showed a decrease by 19 % in the corrosive salt solution and 57 % in the dry‐sliding condition compared with that of untreated sample. The corrosion potential of the sample at 400 °C had more positive potential value and lower current density value than those of at 450 °C. The corrosion resistance of the sample at 400 °C improved due to the positive effect of the retained austenite phase. In this study, the wear was more dominant rather than corrosion, therefore plasma nitrided sample at 450 °C showed the best dry wear and tribocorrosion resistance.
