A policy-based billing management architecture for the next generation IP-based network

High Technology Letters 2006年第3期12卷 300-303页

IP billing is not only a basic functionality to operate IP sen＇ices, but also it is fundamental to offer customers with a stable and QoS-enabled network environment. As IP-based network has been widely agreed to be the core network of NGN, and existing IP billing system is too simple to fulfill the emerging requirements, the next generation IP billing has become an interesting topic in recent years. policy-based management brings flexibility and scalability to systems by describing management logic and functions through policies, and thus reduces the complexity of the management of large-scale systems. Working on existing efforts, this paper proposed an improved IETF policy framework based upon which a policy-based billing management architecture for the next generation IP-based network was presented. Then a prototype with some basic functionalities was developed. The results of the experiment validated the expected improvements specified in this paper.

Resource virtualization has emerged as a promising approach to solving the under-utilized caused by over-provisioning and time-varying resources requests in data center, and rational consolidating workload in a virtualized infrastructure has recently gained considerable attention. A two-tier policy-based consolidation controlling scheme for workload with soft deadline constrain in virtualized data center is proposed. It allows the resources requests to be moderately beyond the resources capacities while allocating both virtual and physical resources on-demand, for the purpose of achieving higher server utilization and energy efficiency without taking the deadline penalty in a best-effort manner. A test-bed with a virtual data center using Xen virtual machines is built based on CloudSim. The experimental analysis indicates that the desired system goals can be leveraged to improve the overall utility.

Note on Three Classes of Data Grid Operations

引用

Journal of Computer and Communications 2014年第6期2卷 1-6页

作者： Arcot Rajasekar Hao Xu Reagan Moore School of Information and Library Science University of North Carolina at Chapel Hill Chapel Hill USA

Traditional grid computing focuses on the movement of data to compute resources and the management of large scale simulations. Data grid computing focuses on moving the operations to the storage location and on operations on data collections. We present three types of data grid operations that facilitate data driven research: the manipulation of time series data, the reproducible execution of workflows, and the mapping of data access to software-defined networks. These data grid operations have been implemented as operations on collections within the NSF DataNet Federation Consortium project. The operations can be applied at the remote resource where data are stored, improving the ability of researchers to interact with large collections.

Towards Cloud Management by Autonomic Manager Collaboration

引用

International Journal of Communications, Network and System Sciences 2011年第12期4卷 790-802页

作者： Omid Mola Michael A. Bauer 不详

The management of clouds comprised of hundreds of hosts and virtual machines present challenging problems to administrators in ensuring that performance agreements are met and that resources are efficiently utilized. Automated approaches can help in managing such environments. Autonomic managers using policy-based management can provide a useful approach to such automation. We outline how collections of collaborating autonomic managers in cloud can be a step towards better management of clouds. We describe how a hierarchy of policy-based autonomic managers can collaborate using messages. The messages and when to communicate is inferred automatically from the policies given to the managers. We evaluate the approach via a prototype inspired by a cloud virtualized infrastructure and show how collaboration between managers in a hierarchy can improve the response time of a web server and avoid service level agreement violations. Results of three different scenarios shows the importance of collaboration between managers at different authority levels and how this collaboration can help to increase efficiency of current infrastructures.

本文的设计思想是在原有吉林省教育学院校园网的基础上构建“硬件+软件+现代教育”模式的新一代多媒体信息网络,使吉林省教育学院校园网在原有教学(科研)、通讯为主要功能的基础上,逐步向数字化校园方向发展,使其成为一个以网络为基础,从环境(包括设备、教室等)、资源(图书、课件等)到活动(教学、管理、办公、服务等)全部信息化的智能网络系统,让信息技术更好的为广大师生服务,此外,在设计构建新一代网络系统的同时,文中还着重阐述了通过系统优化,提高网络安全性、稳定性和高效性的方案与思路,从三个方面对系统行进了以下优化: 1、采用基于策略路由实现多出口方案提升网络性能;策略路由(policy-based Routing)是路由器的一项扩展功能,它不仅能以目的地址为依据来进行路由选择,还可以根据数据包源地址、数据包大小等条件来选择路由。在研究和应用中,主要考虑如何根据源地址及目的地址选择路由走向。 2、通过对路由器及交换机安全加固提升网络安全性;随意篡改IP 地址、恶意访问、黑客程序攻击的情况时有发生, 因此网络系统安全性尤其需要得到重视。通过限制对网络设备自身的访问,增强网络设备自身的安全性。 3、使用JDBC 数据库连接池机制,以有效的实现数据库资源的优化与管理。以JDBC 规范为基础,使用相关的数据库连接池机制,实现有效地管理数据库资源,以提升系统的可用性和稳定性。
