网络

From the Internet to WWW, from the food cycle networks in the environment to the metabolism networks in the creatures' bodies,from the scientific research collaboration network to kinds of political networks,social networks and economic networks, from the large-scale network electronic network to the global traffic network, people live in a world full of varieties of complex networks, which makes the research of complex networks necessary.

从Internet到WWW，从生态环境中的食物链网到生物体中的新陈代谢网络，从科研合作网络到各种政治、经济、社会网络，从大型电力网络到全球交通网络，人们生活在一个充满着各种各样的复杂网络的世界中。这也使得研究复杂网络成为必要。

Based on the comparison of proposed basic topologies, Hypercube, as a popular used topology in networks, has a lot of advantages such as simple routing algorithm, small diameter and average number of internode distance, high fault-tolerance and so on. On the other hand, the network nodal degree which is logarithmically proportional to the number of network nodes limits the Hypercube network population most. So a class of hierarchical topologies are proposed to remedy this weakness of Hypercube and keep most of the advantages of Hypercube, such as CCC , HHC and deCube and so on.

基于对所提出的基本互连网络的性能比较，超立方体网络作为一个得到普遍研究的网络拓扑结构具有很多的优点，比如网络的非常简单的寻路算法，很小的直径和网络平均节点距离，高容错能力等等，但非常遗憾的是超立方体的缺点是超立方体的节点度随着网络规模的增加而成对数关系增加，从而限制了此网络的应用规模，大大地掩盖了它的诸多优点，所以人们提出了一类分层网络结构来弥补超立方体的不足同时最大限度地利用其优点，包括CCC，HHC以及deCube等。

A new knowledge acquirement way is presented based on the reliability data of product, then the fuzzy semantic net which consists of FEPM and fuzzy fault tree is regard as fault knowledge representation. The formalization of the fuzzy semantic net is described, and the relative concepts and relations are summarized. A stereo-knowledge representation which consisted of FFTF, rule and fuzzy neural network which make up of the shallow knowledge of the product is presented. The integrated fault diagnosis method based on the stereo-knowledge representation is suggested. The method is as follows. The fuzzy search inference is carried out on FFTF firstly. If the node being diagnosing can be decided if it failed or not in the fuzzy search inference, the rule inference to the node is carried out with the rules which being in symptom-fault way. An equivalent method, pattern recognization inference using fuzzy neural network, can fulfill the same work.

提出了以FFTF模糊语义网络为主、基于浅知识的产生式规则、模糊神经网络为辅的产品故障知识的立体知识表示方式，并提出了基于该多种知识表示的综合性故障诊断方法，即：首先对故障产品进行基于FFTF模糊语义网络的模糊搜索推理，如果在模糊搜索推理过程中不能确定当前诊断节点故障与否，则对当前诊断节点进行基于征兆-故障形式的验证式规则推理或者对包含该诊断节点的部件／子系统进行基于模糊神经网络的模式识别推理，如果在完成或者不再进行基于模糊语义网络的故障推理，仍然不能诊断出故障节点，则对基于模糊语义网络诊断过程中形成的故障诊断子图进行神经网络推理。

Characteristics of the Internet traffic data flow are studied based on the chaos theory. A phase space that is isometric with the network dynamic system is reconstructed by using the single variable time series of a network flow. Some parameters, such as the correlative dimension and the Lyapunov exponent are calculated,and the chaos characteristic is proved to exist in Internet traffic data flows. A neural network model is constructed based on radial basis function to forecast actual Internet traffic data flow.

覆盖路由网络中数据转发的方法属于覆盖网络中的路由和转发技术领域，其特征在于：通过在现有底层网络中部署覆盖网络路由节点形成覆盖路由网络，为接入的用户主机之间提供完全透明的覆盖路由和数据转发服务，在数据转发过程中，用户的IP分组被封装、转发、解封装，最终发送到目的主机，实验表明在较小规模的覆盖路由网络的全连接拓扑里，同时使用跳数受限机制寻找到的路由路径会比Internet路由性能更高，而且底层网络出现故障时，覆盖路由网络能迅速绕过故障区域，从而提高了端到端的传输性能。
