负载均衡策略是智能网络存储系统(INSS)的关键性技术之一。本文介绍了智能网络存储系统的存储结构,提出了一种新的负载均衡算法。该算法采用周期动态反馈原理,以节点的最小化负载方差为目标,动态调整节点分配权值,最后引入随机概率的转发模式。在实验室搭建的系统平台上,对该算法以及WRR和WLC两种负载均衡算法进行了对比测试,试验结果表明该算法性能更优。 相似文献

目前互联网飞速发展,单服务器的架构已无法满足急速增长的应用负载要求,而常用的负载均衡设备存在很多问题和缺陷,在流量激增与DDOS攻击中成为了新的网络瓶颈,这经常导致服务器无法正常地响应。所以针对以上情况推荐通过对传统DNS负载均衡进行功能扩展使用动态智能DNS来做负载均衡,其优点是克服了传统DNS无法智能判断服务器状态的缺陷,从而可以达到各种昂贵DNS设备类似的功能,并且由于无需链路中增加多余的节点,从而避免了多余的瓶颈与故障点出现。本文表述了智能DNS负载均衡技术的原理、优点、以及实现负载均衡所涉及的关键技术。 相似文献

This paper provides a systematic framework to determine local delivery centre (LDC) locations and service areas to reduce delivery costs and balance the allocation of parcel delivery loads to promote sustainable LDC development. Based on a case study of a parcel distribution company in Korea, this study proposes two strategies for LDC service area delineation within each terminal service boundary that either minimises the total delivery time or balances the allocation of delivery loads. This research contributes to improving cost efficiency and balancing delivery load allocations in planning LDC locations and service areas that can potentially promote the long-term mutual sustainable development of parcel distribution companies and their local delivery counterparts. 相似文献

Optimal location of specialty care services within any healthcare network is increasingly important for balancing costs, access to care, and patient-centeredness. Typical long-range planning efforts attempt to address a myriad of quantitative and qualitative issues, including within-network access within reasonable travel distances, space capacity constraints, costs, politics, and community commitments. To help inform these decisions, single and multi-period mathematical integer programs were developed that minimize total procedure, travel, non-coverage, and start-up costs to increase network capacity subject to access constraints. These models have been used to help the Veterans Health Administration (VHA) explore relationships and tradeoffs between costs, coverage, service location, and capacity and to inform larger strategic planning discussions. Results indicate significant opportunity to simultaneously reduce total cost, reduce total travel distances, and increase within-network access, the latter being linked to better care continuity and outcomes. An application to planning short and long-term sleep apnea care across the VHA New England integrated network, for example, produced 10–15% improvements in each performance measure. As an example of further insight provided by these analyses, most optimal solutions increase the amount of outside-network care, contrary to current trends and policies to reduce external referrals. 相似文献
