If the customer's increase causes the communication volume to exceed the capacity of the server, the result will inevitably be: downtime. Obviously, the limited performance of a single server cannot solve this problem. The processing capacity of a common server can only reach tens of

technology, and Cisco's Etherchannel technology are all studying the link aggregation technology that binds multiple Nic interfaces of the server, the link aggregation technology virtualizes multiple links into one logical link, which provides a cheap and effective way to expand the bandwidth of network devices and servers and improve network flexibility and availability. This article introduces the bonding Technology in Linux. This technology is used in Linux 2.4.x kernel. With bonding technol
