交换技术作为网络底层的核心技术,已走出OSI模型第二层(数据链路层)的空间,渗透到第三层(网络层),甚至第四层(传输层),因而市面上踊跃地出现纷繁的路由交换机,第三层、第四层交换机,甚至多层交换机的概念产品,网络从路由走向交换的趋势由此可窥斑见豹。随着IBM向业界首次公开自己的交换机技术,Prizma作为一交换机芯片,也再一次引起整个业界的关注。 As the core technology of the bottom layer of the network, switching technology has stepped out of the space of the second layer (data link layer) of the OSI model to infiltrate into the third layer (network layer) and even the fourth layer (transport layer) Extensive routing switches, the third floor, the fourth floor switches, and even the concept of multi-layer switch products, the trend of the network from routing to exchange which can glimpse the spotted leopard. As IBM debuted its own switch technology to the industry, Prizma as a switch chip once again aroused the concern of the entire industry.
