可重构网络是在传统网络体系结构僵化、功能单一、可控性差的背景下提出的一种新型网络体系架构，业务聚类是可重构网络的关键机制之一。该文通过对业务聚类需求和聚类算法特性的详细分析，选择了基于平衡迭代规约的层次聚类(Balanced Iterative Reducing and Clustering using Hierarchies, BIRCH)算法来实现业务的聚类；并针对BIRCH对任意形状的簇识别能力差的缺点，设计了一种分裂改进型BIRCH(Advanced Split BIRCH, AS-BIRCH)算法；实验证明该算法在业务聚类方面取得了较好的效果。
Since the traditional network architectures faced the problems of structural rigidity, functional simplification and poor controllability, the reconfigurable network is designed as a new kind of network architecture. In the reconfigurable network, traffic clustering is the key mechanism. By detailed analysis of the requirement of traffic clustering and the characteristics of clustering algorithms, Balanced Iterative Reducing and Clustering using Hierarchies (BIRCH) algorithm is chosen for traffic clustering. However, this algorithm has a poor performance in identifying clusters of arbitrary shapes. In order to solve this issue, an advanced algorithm named Advanced Split BIRCH (AS-BIRCH) is designed. Experimental results demonstrate the effectiveness of AS-BIRCH in traffic clustering.
