【Abstract】: In era of network development, it is an inevitable trend to research stability and reliability of computer network. Under condition of fixed network resources, increasing application of network resources in unit link is the core of optimization of whole network system. Through modified genetic algorithm, under judgment of satisfaction and fitness index function, we can change performance of network, control constraints of network through iterations, and optimize design according to function verification. The paper studies relationship between cost of network improvement and iterations to verify results of genetic algorithm optimization, provides practical data basis for computer network reliability optimization design.

0 ?引言
計算機網(wǎng)絡可靠性的研究是計算機發(fā)展的必然趨勢,在計算機區(qū)域連接和網(wǎng)絡連接相互拓展的過程中,信息網(wǎng)絡技術的發(fā)展成為結構化發(fā)展的先決條件,人們越來越多的依賴于信息技術,同時計算機網(wǎng)絡在一些重要的領域用途也很關,對經(jīng)濟、社會和國防等方面都有很長遠的影響。信息網(wǎng)絡的可靠性是提高網(wǎng)絡質量的重要評判標準,在拓撲結構中利用程序上的改變和優(yōu)化,能夠強化網(wǎng)絡的能力,降低網(wǎng)絡的造價,對穩(wěn)定性有很好的幫助作用。在本文中就是以改進遺傳算法的方式強化計算機網(wǎng)絡可靠性。
目前在我國計算機網(wǎng)絡穩(wěn)定性的研究基于電信信號網(wǎng)絡的交換研究[1],在網(wǎng)絡信號故障的基礎上,利用電信信號的傳輸實現(xiàn)容量的改變,在信號交換的情況下實現(xiàn)傳輸。……
