Middleboxes are widely deployed to perform various network functions to ensure security and improve performance. The recent trend of Network Function Virtualization (NFV) makes it easy for operators to deploy software implementations of these network functions on commodity servers. However, virtual network functions consume different amounts of resources when processing packets. Thus a multi-resource...
Middleboxes are prevalent in today's enterprise and data center networks. Network function virtualization (NFV) is a promising technology to replace dedicated hardware middleboxes with virtualized network functions (VNFs) running on commodity servers. However, no prior study has examined the energy efficiency of different NFV implementations. In this paper, we conduct a measurement study on the power...
The coverage region of WLAN network is limited compare with cell phone system such as GSM and WCDMA. The favorable area to deploy WLAN is the area which has strong demand for wireless network. How to identify the needs and guide the deployment of WLAN, that isn't a easy issue. It will waste the investment if we deploy the WLAN in improper places. This paper proposes a solution which can collect customer...
Long period of petroleum exploration has accumulated mass materials of multi-source and multi-scale correlated with geographical position, including seismic, logging and geological data, etc. However, the present management system of the petroleum company cannot integrate and manage these materials effectively, making it difficult to organize and share the information. With the application of GIS,...
Integrated from the three articles on Vague plan, the paper advanced the Vague plan optimization algorithm, which proposed the definition of the transforming formula from the single data to Vague data, and also put forward two transforming formulas from the single data to Vague data, and proposed one similarity measure formula among one Vague set. The two formulas are the basic foundation of the Vague...
In this paper, a series of new formulas for similarity measure between vague sets (values), as well as a direct transforming formula from single-valued datums to the vague-valued datums are presented. The application example in a field of psychology proves these formulas to be practicable.
Using software agents as next generation flexible components and applying reuse technologies to rapidly construct agents and agent systems have great promise to improve application and system construction. Agent-based approach in software engineering is regarded as a promising technique in the development of software. First, a principle and method structured data object based for simplifying the complex...
