Abstract

There is a trade-off problem among diameter, scalability and path length of structure designing in Data Center Network. Therefore, many papers had provided the solution called embeddability, which is an indicator to measure the ability of combining advantages of different networks. This paper considered grid embeddings as an example because they have many applications such as simulation capabilities of a parallel architecture, designing VLSI layout etc. As a modification of the hypercube, Cube-Connected Cycles (CCC) has good symmetry, low diameter and strong connectivity. In this paper, we focused on the minimum wirelength in the linear layout and grid layout of the CCC. Firstly, we analyzed the recursive structure characteristics and properties of CCC. Then, the maximum induced subgraph of CCC is obtained by theoretical analysis. Next, an embedded mode is proposed to layout CCC onto a linear array and we derived an exact formula for the minimum wirelength. Furthermore, we devised an optimal embedding of the n-dimensional CCC onto a grid network.
在网格网络中嵌入立方体连接循环的最小无线长度
数据中心网络结构设计存在直径、可扩展性和路径长度之间的权衡问题。因此,许多论文提出了一种称为可嵌入性的解决方案,可嵌入性是衡量不同网络结合优势能力的指标。本文以网格嵌入为例,因为网格嵌入在并行体系结构仿真、超大规模集成电路布局设计等方面具有广泛的应用。立方体连接环(CCC)作为超立方体的一种改进形式,具有良好的对称性、低直径和强连通性。在本文中,我们重点研究了CCC的线性布局和网格布局中的最小布线长度。首先,分析了CCC的递归结构特点和性能。然后,通过理论分析得到了CCC的最大诱导子图。其次,提出了一种嵌入式模式,将CCC布局到线性阵列上,并推导了最小无线长度的精确公式。此外,我们还设计了一种将n维CCC嵌入网格网络的最佳方法。
