WTO规则视野下的《网络安全法》

中国2016年颁布的《网络安全法》,从立法前的研讨和意见征集,到法律之后公布和推进以及配套制定和实施的细则和指南等,都引起了全球各国和组织的重视和讨论,而国内的单一立法很少能够如此激起国际社会的广泛关注。本文将从WTO规则的角度来分析《网络安全法》是否存在和现行国际法规则的协调或者是合规性的问题。一般意义而言,目前在整个国际法规则的层面,网络空间的国际法和规则并不适用于所有的现行规则,但是现有的国际法规则可以适用于网络空间的管制和网络安全,其中比较有代表性的是WTO规则。普遍意义上,众多网络行为和商务交易相互关联,比如通过网络形式进行交易的贸易活动。

Cloud download system optimizing by job and notification scheduling

With expansion of cloud-based applications, it is necessarily for business service provider to deal with how to provision resources to server customers. In cloud download, the service provider faces great challenge on determining when to process job and when to notify the user to meet the conflicting objectives, i.e., the service profit maximization and user satisfaction maximization. An economic model was proposed to find job and notification scheduling strategies for making tradeoffs between user satisfaction and profit of the system, in this model, optimization problems are formulated as follows, profit maximization under a satisfaction target and then satisfaction optimization with a profit bound. By solving these optimization problems, the optimal scheduling strategies are obtained under various quality requirements of service. It is demonstrated that the proposed strategy can obtain better performance than the system without the intelligent scheduling strategy.     

Analysis of cooperative and competitive spectrum sharing for heterogeneous networks based on differential dynamics model

The heterogeneous networks belonging to different service providers form a coalition system for maximizing the profit, where they may either compete or cooperate with each other. In this paper, we introduce the Lokta–Volterra model, a differential dynamics model, to build the competitive and cooperative mechanisms of heterogeneous networks. It considers the natural growth rate of the network itself and competitive and cooperative effects among networks. Then, according to the ordinary differential principle, the stability of the proposed model and its equilibrium points are analyzed. And finally, system performances are evaluated by Vensim that is used for developing, analyzing, and packaging dynamic feedback models. Analysis and simulation results show that the natural growth rate of the network cannot increase its profit, but effective cooperative mechanism among heterogeneous networks can increase the profit of each network.

Competitive Analysis of Online Traffic Grooming in WDM Rings

This paper addresses the problem of traffic grooming in wavelength-division multiplexing (WDM) rings where connection requests arrive online. Each request specifies a pair of nodes that wish to communicate and also the desired bandwidth of this connection. If the request is to be satisfied, it must be allocated to one or more wavelengths with sufficient remaining capacity. We consider three distinct profit models specifying the profit associated with satisfying a connection request. We give results on offline and online algorithms for each of the three profit models. We use the paradigm of competitive analysis to theoretically analyze the quality of our online algorithms. Finally, experimental results are given to provide insight into the performance of these algorithms in practice.      

关于出租车载客地点序列推荐技术的研究

在大城市中,出租车已成为实现智能交通运输系统不可或缺的一环。然而,由于一些出租车司机的驾驶经验,和对城市活动的熟悉程度的不足,使得其在寻找乘客时会采取毫无目的的随机漫游策略。这就导致了出租车司机的收益不高,同时也造成了能源的消耗以及环境的污染。针对此问题,将提出出租车载客地点的推荐模型,使得模型给出的推荐地点序列能获得较高的期望收益。具体来说,将基于出租车GPS轨迹数据建立出租车载客地点的马尔科夫决策过程模型,并给出求解该模型的2种算法。仿真实验结果显示,与典型的TopK方法相比,给出的推荐结果能更好地提高单位时间内出租车司机的收益。     

Adaptive Cooperative Spectrum Sharing Based on Fairness and Total Profit in Cognitive Radio Networks

A cooperative model is presented to enable sharing of the spectrum with secondary users. Compared with the optimal model and competitive model, the cooperative model could reach the maximum total profit for secondary users with better fairness. The cooperative model is built based on the Nash equilibrium. Then a conceding factor is introduced so that the total spectrum required from secondary users will decrease. It also results in a decrease in cost which the primary user charges to the secondary users. The optimum solution, which is the maximum total profit for the secondary users, is called the collusion state. It is possible that secondary users may leave the collusion state to pursue the maximum of individual profit. The stability of the algorithm is discussed by introducing a vindictive factor to inhabit the motive of deviation. In practice, the number of secondary users may change. Adaptive methods have been used to deal with the changing number of secondary users. Both the total profit and fairness are considered in the spectrum allocating. The shared spectrum is 11.3893 with a total profit of 65.2378 in the competitive model. In the cooperative model, the shared spectrum is 8.5856 with the total profit of 73.4963. The numerical results reveal the effectiveness of the cooperative model.     

Bid markup selection models by use of multiple criteria

Multiple attribute decision modeling is proposed for determining the most preferred bid markup in a competitive bidding situation. In this note, a previously proposed model is extended by introducing two new bidding criteria, called the conditional positive profit and the expected positive profit ratios, respectively. Three two-criteria decision models and a single criteria decision models using the newly introduced criteria are proposed to determine the bidder's most preferred markup level. The simple additive weighting method and the weighting product method are used to solve these models. Two numerical examples are used to illustrate the different rankings that are obtained when different models and solution methods are used. The results demonstrate that the bidder's preference over the set of bidding criteria has a significant effect on the selection of the bid markup     

Effect of intermittent repair in a two unit redundant system with standby failure

A two-unit standby redundant system with exponential failure time distribution of the operative unit is considered. It is assumed that failure of the standby unit is detected only at the time of use and is available with a known probability. Repair facility is also available at the time of need with a known probability. Repair and preoccupation times are general. Stochastic behaviour of the system has been studied by Semi-Markov process and parameters of interest eg. MTSF, steady state availability, expected profit have been obtained. Expected profit of this model is compared with that of an earlier model and a condition on extra incurred cost is obtained.
