摘要
宽带综合业务数字网（ＢＩＳＤＮ）采用异步转移模式（ＡＴＭ）作为其传输技术，引入了虚通道（ＶＰ）和虚通路（ＶＣ）概念．本文针对ＢＩＳＤＮ中的ＶＰ路由问题，提出了一种基于Ｈｏｐｆｉｅｌｄ神经网络的ＶＰ路由选择算法，给出了神经网络能量函数的表示方法及神经元的状态方程．计算机模拟结果表明，本算法能根据网络的物理结构和业务需求情况，快速、有效地实现ＶＰ路由选择，提高网络的生存性．
Broadband Integrated Services Digital Networks (B ISDNs) adopt Asynchronous Transfer Mode (ATM) as target transmission technology,with virtual path (VP) and virtual channel (VC) concepts introduced.In this paper,we propose a new VP routing algorithm based on Hopfield neural networks in B ISDN,set up the energy function and neuron state equation.Simulation shows that in accordance with the network topology and traffic pattern the proposed algorithm is both fast and effective to achieve VP routing and improve the network survivbility level.
