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 paper presents a new Cyber Physical Stream algorithm for selecting a predominant item from very large collections of data. The algorithm effectively works for frequencies of the predominant items starting from about 2%. The algorithm is focused on querying massive data in Software-Defined Storage combined with Fuzzy indexing method. Experiment results show that Cyber Physical Stream algorit...

Software-Defined Networking (SDN) increasingly attracts more researchers as well as industry attentions. Most of current SDN packet processing approaches classify packets based on matching a set of fields on the packet against a flow table and then applying an action on the packet. The authors argue that it is possible to simplify this mechanism using single-field classification and reduce the ...

We list some Software Defined Networking (SDN) products that support the Group Table ALL feature which can be used to forward incoming packets to multiple outgoing ports via packet replication.
