It is a main task of general topology to compare different spaces. mappings which connect different spaces are important tools to complete it. which mapping preserves some special generalized metric space is a basic probleme in investigating generalized metric spaces by mappings. g - first countable spaces and g - metri / able spaces have many important topological properities so to investigate which mapping preserves them is very necessary. in [ 7 ], clnian liu and mu - ming dai prove that open - closed mappings preserve g - metri / able spaces ; whether open mappings preserve g - first countable spaces is an open probleme asked by tanaka in [ 6 ]. in [ 4 ], sheng - xiang xia introduces weak opewn mappings and investigates the relations between them and 1 - sequence - covering mappings. in the second section of this article, we investigate weak open mappings have the relations with other mappings and prove that the finite - to - one weak open mappings preserve g - first countable, spaces and weak open closed mapping preserve g - metrizable spaces. in the third section, we investigate an example to show that perfect mappings do not preserve g - first countable spaces, g - metrizable spaces, sn - first countable spaces and sn - metrizable spaces

The beginning point of the first research direction is that we design a type of load - balancing virtual topology which is insensitive to the traffic, such plan method has been proposed whose name is vlbs ( valiant load - balancing schemem ), the disadvantage of vlbs is that it can only be applied to the homogeneous network in which each node has the same capacity, in chapter2, a more general valiant load - balancing scheme ( gvlbs ) has been proposed, the advantage of the gvlbs is that it can be used both on the homogeneous network and heterogeous network, in this chapter, we will give the detail derivation process and numerical analysis. the beginning point of the second research direction is that we first design a virtual topology for the physical topology under a specific traffic matrix, for a while, the traffic has changed, the network performence will decline. under such condition, in chpater 3, a virtual topology reconfiguration algorithm is studied which can decrease the average weighted hops
本文針對動態變化業務量情況下的wdm網路設計方法劃分為兩個主要的研究方向，第一個方向的研究出發點是可以在最初的虛拓撲設計過程中根據物理拓撲情況設計出一種虛拓撲出來，該虛拓撲是負載均衡的，在這種虛拓撲上跑的業務量矩陣特徵只要在某種范圍以內，無論它怎樣動態變化，網路都不會出現擁塞，但這種虛拓撲設計演算法vlbs的一個缺陷是它只能適用於同構網路，即每個節點所擁有的容量大小都相等，在第二章中，本文提出了一種更通用的負載均衡的光網路虛拓撲設計演算法gvlbs ，該演算法與傳統的負載均衡演算法vlbs不同之處在於vlbs演算法只能適用於同構網路而gvlbs演算法既可以適用於同構網路，又可以適用於異構網路，在本章中將給出了gvlbs演算法的的詳細推導和數值分析。 -
