software asset repository is a primary infrastructure of Asset-Based software Engineering. Now asset repositories are usually built into isolated islands and are browsable or searchable only by people, which has substantially reduced their functionality and greatly hindered the reuse in practice. Based on service-oriented approach, we proposed a lightweight open framework for sharing reusable assets among diverse repositories and thirdpart tools, which is characterized by supporting customizable faceted classification. We described the runtime reference architecture, UML object model and programmatic service interfaces which together provided a comprehensive technology-enriched specification for opening and sharing asset repository.

This paper proposes a new collaborative design method, which is developed from the study of dependencies between the parameters of each part of apparatus, and can be devoted to solve the problems of collaborative product design of multiple domains between several communities based on computer networks, and be applied to the design process such as electrical application and mechanical product etc. This paper covers the emerging issues and the persistent requirement of collaborative product design in electrical industry, and then elaborates the foundation ideas and formal definition systems of dependency, and the corresponding architecture.

Recently, more and more services need high quality bandwidth. In order to satisfy those services, high-speed networks are needed. The Task Force team of IEEE 802.3ah set a standard as Ethernet Passive Optical Network (EPON) that is a next generation subscriber access network. IEEE 802.3av developed 10G EPON which has 10 times more capacity than EPON to solve the high quality problem. Research on 10G EPON has been conducted by Kramer, but still there were limitations in providing Quality of Service (QoS). Therefore, this paper suggests a Time synchronization method, resource reservation method, and bandwidth allocation method in 10G EPON. The OPNET simulation results show that our proposed ideas can provide enough services in 10G EPON.

With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster, Online-payment platform is needed urgently. In this paper, the protocol in the bank-side is analyzed, and then payment platform architecture is proposed which is based on the SaaS standard and supports distributed deployment. Finally, Key technologies applied to imply this platform are also described in detail.
