Software-defined networking (SDN) and network functions (NF) are two essential technologies that need to work together to achieve the goal of highly programmable networking. Unified SDN programming, which integrates states of network functions into SDN control plane programming, brings these two technologies together. In this paper, we conduct the first systematic study of unified SDN programming. We first show that integrating asynchronous, continuously changing states of network functions into SDN can introduce basic complexities. We then present TRIDENT, a novel, unified SDN programming framework that introduces programming primitives including stream attributes, route algebra and live variables to remove these complexities. We demonstrate the expressiveness of TRIDENT using realistic use cases and conduct an extensive evaluation of its efficiency.

This paper proposed a new evolutionary algorithm for generating trading rules on stock market, which is called Probabilistic Genetic network programming (P-GNP). P-GNP represents its solutions using graph structures based on probability. It has been clarified that P-GNP works well especially in dynamic environments. In the proposed hybrid stock trading model, P-GNP is applied to generating stock trading rules using variance of fitness values and probability. The unique point is that the generalization ability of P-GNP is improved by considering the robust fitness function and the Q value of the branch obtained by Sarsa Learning. Generally speaking, the hybrid intelligent system consists of three steps, the priority selection by portfolio beta, the optimization by Genetic Relation Algorithm (GRA) and stock trading by P-GNP. In the simulations, the stock trading system is trained using the stock prices of 10 brands selected from the Nikkei 500 Index, then the generalization ability is tested. From the simulation results, it is clarified that the trading rules created by the proposed P-GNP model obtain much higher profits than the traditional methods and its effectiveness has been confirmed.

Current frameworks for network programming assume that the network comprises a set of homogenous devices that can be rapidly reconfigured in response to changing policies and network conditions. Unfortunately, these assumptions are incompatible with the realities of modern networks, which contain legacy devices that offer diverse functionality and can only be reconfigured slowly. Additionally, network service providers need to walk a fine line between providing flexibility to users, and maintaining the integrity and reliability of their core networks. These issues are particularly evident in optical networks, which are used by ISPs and WANs and provide high bandwidth at the cost of limited flexibility and long reconfiguration times. This paper presents a different approach to implementing high-level policies, by pushing functionality to the edge and using the core merely for transit. Building on the NetKAT framework and leveraging linear programming solvers, we develop techniques for analyzing and transforming policies into configurations that can be installed at the edge of the network. Furthermore, our approach can be extended to incorporate constraints that are crucial in the optical domain, such as path constraints. We develop a working implementation using off-the-shelf solvers and evaluate our approach on realistic optical topologies.

Compete with the big players in today's E-commerce marketplace Electronic Data Interchange (EDI) has long been the standard for large business enterprises to communicate in the B2B marketplace. However, EDI is a difficult technology - the cost and support of EDI standards is often too much for a small or medium business enterprise to bear. To compete in the current E-commerce marketplace, many organizations are beginning to take an interest in the interoperability that exists between XML (Extensible Markup Language) and EDI. XML .NET Developers Guide is written for information technology professionals responsible for supporting data management in both small and large organizations. This book appeals to both individuals working with an existing EDI environment, and small to medium businesses looking to increase their market presence by competing with current EDI players using XML/EDI.

The conventional approach for building software-defined network systems requires separately developing the management, control, and data planes. Manually written code connects the management plane's configuration to the control plane, and the control plane generates the data planes' configurations as small program fragments that scatter across the codebase. Scalability and correctness become increasingly challenging as such a system develops and grows. In contrast, in our approach, called Nerpa, all three planes are programmed in a unified way. In Nerpa a transactional database stores management plane state. The control plane is implemented in a specialized query language which automatically executes in an incremental fashion, improving scalability. Finally, the data plane is programmed in P4. To aid correctness, all three parts are type-checked together, and tools generate code for data movement between planes. We have published a prototype implementation using an open-source license. We believe that full-stack SDN can build more robust and maintainable networked systems.

The rapid development of the computer networks has been making a great influence in many fields of human society. Among a great many networks operating systems, Linux is obtaining more and more attention from people by its excellent behavior. The task is to develop an e-mail system based on a lan with Linux as its operating system. This article includes two parts. In part one;we will make an introduction to Linux operating system and the network programming environment in Linux. In particular, the BSD socket functions are analyzed in great detail, for they will be used in later programming work. In part two, we present the implementation of our mail system, from whole designing to detail designing, and the C program source files written by me is attached to the end of this article.
