第三层交换策略层出不穷,主要分: (1)基于ASIC(Application-Specific Integrated Circuits)的路由方式实际是将软件实施的路由方式交由硬件实现,与传统路由方式并无差别,但转发数据包的速度却显著提高,同时成本也明显降低。 (2)由于传统路由方式是按“一跳接一跳”(hop-by—hop)方式完成数据包发送,在发送端和目的端间,数据包要依次经过多个路由器,这是致使路由方式速度低的主要原因。直通方式就是要在发送端和目的端间建立一条通路,使数据包避开多余的路由器。 (3)卷标技术在包头加标记,使数据包在转发时可以不考虑IP地址,以提高转发速
The third layer of exchange strategy emerges in an endless stream. The main points are as follows: (1) Application-Specific Integrated Circuits (ASIC) -based routing method actually implements the routing of software implementation by hardware and does not differ from the traditional routing method. However, The speed is significantly increased, while the cost is also significantly reduced. (2) Since the traditional routing method is to perform data packet transmission in a hop-by-hop manner, the data packet passes through multiple routers in sequence between the sending end and the destination end, which is caused by the routing The main reason for low speed. Through way is to establish a path between the sending end and the destination end, so that packets avoid the excess router. (3) Labeling technology in Baotou tagging, so that data packets in the forwarding can not consider the IP address to improve the forwarding speed
