The Simulation Research of Campus Network Technology Based on IPv6

Abstract

Aiming at the issues of smooth transition from IPv4 to IPv6 and interoperability in technical coexistence period about campus network, discussing the technical characteristics of IPv6 protocol, GNS3 and OPNET simulator, combined with the status of weakness of IPv6 technology, lack of IPv6 technology planning and financial support for network upgrade in the vast majority of colleges, adopted the simulation methods to build a network model of IPv4 and IPv6 to achieve the technologies study such as topology design, network configuration and testing, network performance design and evaluation of IPv6 campus network under the low-cost conditions.

Research on Model-Based User Interface Automatic Generation in SaaS Environment

“…These standards not only used to inspect the characteristic support for user interface at design time, but also they could use to reason the usability while user interface was produced at runtime. In paper [7], a method that created the executed models of human and machine interaction was provided. But all these methods focused on solving the models modification problems by the context at runtime.…”

Deep Web Database Selection with Classification and Rich Features

“…So, the problem of Web database selection has been a primary challenge to internet-scale deep web data integration. The problem has been studied by several researches such as [2][3][4] [5] [6]. In these methods, relevancy between the user query and Web databases is usually calculated according to their local statistics, for example DF which is referred to as the document frequency of the query in the database, and their similarity, such as standard cosine function using TF-IDF measure.…”
