A Study of "Code Switching" for all-optical switching network

提出了一种新的交换概念“码交换”，并在此基础上提出了一种全光码交换网络。相同的数据块在所有网络上广播，并通过光CDM方法进行复用。然后，每个节点可以接收相同的广播数据，然而，每个节点只能提取由每个节点的代码编码的每个数据。为了实现高效的全光交换网络，本研究从网络结构、节点配置和交换协议等方面进行了深入的研究。

A novel exchange concept “Code Switching” is proposed, and based on this concept, an all-optical code switching network is proposed. Same data blocks are broadcasted on all of network which are multiplexed by optical CDM method. Then, every node can receive same broadcasted data, however, each nodes can only extract each data which is coded by code of each node. Architecture, node configuration, and switching protocol are basically studied in this research for realizing efficient all optical switching network.
