let $mathcal{r}$ be a  commutative ring with identity, let $a$ and $b$ be two $mathcal{r}$-algebras and $varphi:blongrightarrow a$ be an $mathcal{r}$-additive algebra homomorphism. we introduce a new algebra $atimes_varphi b$, and give some basic properties of this algebra. generalized $2$-cocycle derivations on $atimes_varphi b$ are studied. accordingly, $atimes_varphi b$ is considered from th...

the goal of this work is to present a case study demonstrator, presenting the field trial experience while extending network connectivity services in the campus, by enabling SDN-based equipment and coexisting with legacy hardware. The demonstrator aims to show the benefits of gradually adopting SDN technologies. This adoption will also improve and provide added value to traditional campus conne...

In this paper, we propose our on-going effort for developing NetOpen networking service that supports extended flowbased networking with programmable network substrates.

This paper presents in the area of software defined networking. Our aim is to identify limitations of current networking technologies and how software-defined networks (SDN) could reduce cost, and improve competence to provide significant business value to many enterprises and campus Networks for their network management . These outcomes can lead to increased market potential for contenders whi...
