摘要
提出以树状结构和数据信息分离的八叉树数据结构为基础,并结合四面体格网来建立面向对象的数据模型,并将其应用于计算电磁学中的三维介质体建模,从而达到减少存储空间,方便、快速的搜索到所需数据,建立模型更为精确的目的。这一方法可用于加快多层快速多极子(MLFMA)算法和射线跟踪法的计算速度。
This article proposes the most prospective network scheme in the future- the technology of GMPLS, and its survivability strategy. First we discuss the relationship and difference between GMPLS and MPLS on architecture, working process, routing and signaling protocols, especially the enlargement and renewal on these aspects when the optical network is introduced. Then we talk about the survivability strategy of GMPLS, analyze the current research situation and the main problem to be solved. At last we introduce the rerouting mechanisms in detail.
