ＡＴＭ网络中的ＶＰ层网络规划在大规模网络情形下求解会发生困难，文章借鉴了ＰＮＮＩ网络递阶结构，设计了一种分级规划方法，有效地解决了大规模ＡＴＭ网络ＶＰ层规划问题，并用进化规划对规划问题进行了求解。文中给出了数值算例。
ATM network VP network planning in large-scale network situation will be difficult to solve. The article draws on the PNNI network hierarchical structure, a hierarchical programming method designed to effectively solve the VP layer large-scale ATM network planning problems, and use Evolutionary planning solves the planning problem. Numerical examples are given in the paper.
