一种软件定义无线网络负载均衡架构及算法

软件定义网络（SDN）为实现异构无线网络中的负载均衡提供了新的思路。设计了一种软件定义的无线网络负载均衡架构，并提出对应算法。首先，根据接收信号强度构建候选网络列表；其次,根据各候选网络的可用负载比率标准差进行负载差异分级；再次，将服务质量匹配度函数和负载均衡指数线性组合成联合优化函数，并根据负载差异分级对联合优化的权重进行动态调整，合理设置门限进行接纳控制。与传统算法相比，所提算法一方面可使各类业务阻塞率明显降低大约20%，另一方面使不同网络的归一化负载更加接近。该算法在进行网络负载均衡的同时，能够有效降低业务阻塞率，从而有效提升异构无线网络的整体性能。

Network impacts of distance-based road user charging

Distance-based road user charging is being seen as one potential mechanism to implement national road charging schemes. This paper investigates the design aspects of universal distance-based charging schemes and incorporates procedures within a detailed network supply model to represent how a range of different permutations of distance-based charges across a given network (charging regimes) affect route-choice, travel characteristics and demand for road space. The results suggest that distance-based charging can reduce number and length of trips, congestion, accidents and pollution, and provide net economic benefits and revenues. However, these benefits are not found to be uniform throughout the network. Their magnitude largely depends on the charge level, the hierarchy of charges across the network, and the difference between the charge levels.

基于现有技术条件下我国电动汽车商业化之路

目前我国电动汽车的发展进入了瓶颈阶段,即无法实现商业化。制约电动汽车商业化的障碍主要有:电池充电时间长,效率低;整车价格贵、汽车整体运行成本高;缺乏足够的充换电网络和专业的维修网点。在现有技术条件下解决电动汽车商业化的有效途径是采取换电模式,其优点为:没有技术障碍问题、换电站投资成本低、缩短车辆的等待时间、提高电池的使用寿命、降低电池的使用成本。目前应由国家制定统一的电池标准和充电设备等标准,并依托中石油、中石化、南方电网等央企来构建充换电网络。     

Bottom-up framework for cost allocation to services in telecommunication networks

Communications service providers (CSP) supply information, transport and passive infrastructure services that rely on the deployment of multiservice networks. To attain service cost reductions, the planning and design of those networks is essential, so that the total cost of the network ownership (TCO) is minimized. In this paper, we propose a bottom-up calculation framework for the allocation of the TCO cost components (i.e. capital and operational expenditures) to the services supplied by a CSP. For this, the framework is formulated within the context of the network life-cycle. Our method provides the level of abstraction required for the calculation of the three basic service cost contributors, namely, direct, shared and common costs. Moreover, it outlines the role of network planning in the design of an efficient network infrastucture, and in the calculation of the TCO. Based on this, we show how the stand alone, fully allocated and long-run incremental costs of a service can be calculated. Besides the determination of service cost drivers, the framework is useful to evaluate the cost-efficiency of competing technologies. To illustrate this, we study the allocation of the infrastructure costs for a CSP offering transport services with an optical network. By designing the infrastructure with fixed-grid and flex-grid technologies, it is shown that in both cases the main service cost driver is determined by the transponders installed. The results show that fixed-grid fits well for the provisioning of high speed constant bit-rate transport services, whereas flex-grid is a good candidate for transport services with bursty traffic patterns.     

借记卡收费的网络视角分析

与国际同业收费标准相比,目前我国借记卡收费属偏低水平。借记卡是一种典型的具有网络效应的产品,其网络价值随着持卡人数和硬件终端分布数量的增多而提高。银行终端系统兼容性的提高在一定程度上降低了持卡人的转换成本,这将对借记卡的市场结构和网络效应的作用形式产生很大影响。银行应提高借记卡服务的差异化,应通过增加投入来进一步完善网络,提高自身的服务水平与效率,通过不断增加客户的效用,进一步发挥网络效应的作用。     

Arrow: A flexible architecture for an accounting and charging infrastructure in the Next Generation Internet

Current pricing and charging methods for the Internet are not based on actual usage of this service, which leads to unfairness and more important, it does not deliver the right signals through financial incentives to network providers to upgrade critical links of their networks. The development of new multimedia applications and the convergence to an integrated services network will foster the tremendous growth of the Internet even more. With the Next Generation Internet not only technical services like bandwidth reservation will be introduced, but also new applications will emerge within the Internet. Charging the Internet in a fashion that provides feedback to users and providers has been proposed since the early '90s, however, only a few implementations and real-world examples are known today. This is due to subsidizing the Internet in its early stages and due to a technical development that did not care much about charging. With the recent redesign of the Internet protocol suite and discussions on multiple service classes in the Internet, architectures for charging and accounting have to be revisited, too. Economic models for the Internet cannot be tested fully and validated in non-real-world environments, because of the unknown user behavior. With this uncertainty over what models and pricing schemes to choose, it is evident that a specific charging and accounting platform will never be accepted by the community. In this paper a novel and flexible architecture for charging and accounting is proposed that provides a wide range of mechanisms and lets researchers experiment in an environment as close as possible to the targeted system. As a first step, four different pricing schemes are described, qualitatively assessed on the proposed platform, and a prototypical implementation performed. One of the economic models that have been implemented on Arrow is based on different service classes including reservation and recalculates prices dynamically depending on the traffic situation.

中国大型商业银行中间业务的SWOT分析及战略选择

当前,中国大型商业银行既具有自身具有营业网络、客户资源、资金等优势,也存在着资产质量不高、金融创新和风险管理不足、收费标准不规范、专业人才匮乏等劣势;既面临着经济环境、金融混业经营的趋势、相关法律法规的逐步完善以及科学技术进步带来的发展机遇,也面临着人才和客户流失以及外资银行的威胁。中国大型商业银行应该抓住外资银行尚未形成绝对优势地位的有利时机,采用SO战略和WO战略,即扭转型战略和差异化战略,充分利用自身特有的优势,改善经营环境,加快推进金融创新步伐,拓展业务空间,努力提升市场竞争力。     

Pricing of card payment services in Scandinavian banking

Pricing of card payment services includes many considerations of cost and revenue in an environment of changing payment technology, network effects in two-sided markets and price bundling. This paper describes the consumer pricing methods for card payment services by Scandinavian banks and evaluates their explicit pricing methods. The main findings suggest that Scandinavian banks in general are more interested in earning revenue from implicit prices than in encouraging the use of more cost efficient technology by charging explicit transaction fees. However, the pricing methods applied may vary, depending on the country and a bank's service supply.
