摘要
应用Dixon结式对一种5-5型台体并联机构进行了位置正分析,得到了其一元40次输入输出方程,由此求得全部位置正解,计算结果无增根.运算过程借助于计算机代数系统Mathe-matica2.0和MapleV进行符号推导,使输入输出方程形式上由48次降为40次,完成了严格的证明.
A TMN based network survivability management system (NSMS)is proposed. It includes: global survivability control (GSC), spare resource control, network survivability status monitor, its MIB (management information base), and traditional fault management. Different restoration techniques may be deployed at ATM and SDH layer, due to techniques and cost restraints. A global survivability control (GSC) for SDH based ATM networks is proposed as a part of NSMS to get better survivability cost feature. GSC preplans and downloads different response procedures for every network element (NE) at different layers, according to overall information of the network. Cooperation between different restoration techniques in SDH and ATM layers is deployed a hybrid escalation mechanism for SDH/ATM networks. It is based on sequential activation of restorations and TMN related function (e.g., NSMS) involved control in case of some special situations. NSMS including GSC may lead to construct cost effective survivable SDH based B ISDN networks.
