Finally , when the edge life is exponentially distributed , the paper computes the bounds of all - terminal reliability of a sdh network to demonstrate the method 最后在網(wǎng)絡(luò)鏈路壽命服從指數(shù)分布時分析了某sdh傳輸網(wǎng)絡(luò)的全端可靠性以及界的計算,以說明本文的方法。
Although the 2 - terminal reliability problem has been widely studied for networks with unreliable links , a little is known about the problem for networks with unreliable nodes 目前,對于具有邊不可靠而點可靠的網(wǎng)絡(luò)可靠度的研究已經(jīng)很多,而rbn的可靠度的研究還很少。
Computing the coefficients is the key to obtain the all - terminal reliability of communication by using reliability polynomial , and computing some coefficients exactly is np - hard 摘要用可靠性多項式計算網(wǎng)絡(luò)全端可靠性的關(guān)鍵是多項式中系數(shù)的,精確計算各系數(shù)是一個np難問題(上標[ 1 ] ) 。
