Centralized switching : Switching decisions are made on the route processor by a central forwarding table, typically controlled by an ASIC. 集中交换:用路由处理器(RP)生成的集中的路由处理器(RP),例如使用ASIC。
Distributed switching : Switching decisions can be made on a port or line-card level rather than on a central route processor. 分布式交换:在端口上达到比集中交换更快的线速。
Route Switch Solutions Based on Network Processor 基于网络处理器的路由交换方案
The idea of the collaborative software and hardware design, which will be a new route of later design work, is differ from the concept of traditional processor design. SOPC设计的软硬协同的理念不同于传统处理器设计思想,它的全新的设计理念为以后的设计工作指明了一条新路。
