When early multi-WAN router products are on the market, some vendors directly modify the hardware functionality on a single WAN router, wh
With the development of China's routing industry, WAN port broadband routers are also widely used. Here we mainly introduce the role of Server Load balancer in the Development of WAN port broadband routers, the technical differences between the multi-WAN port broadband routers are not very large.

Bind two network cards, share one IP, realize the redundancy effect. In fact, there are 7 types of bindings for Linux dual NICs:
The mode=0 indicates that load balancing (round-robin) is balanced, and both NICs work.
mode=1 says Fault-tolerance (active-backup) provides redundancy, working in a master-slave way, which means that only one NIC works by
In Linux, dual-Nic binding technology achieves load balancing and failure protection (in Centos5 and Centos6). maintaining high server availability is an important factor in the enterprise IT environment. The most important thing is the high availability of server network connections. NIC binding helps ensure high availability and provide other advantages to impr

If the Curr_active_slave fault, its hardware address will be newly elected to the Curr_active_slav
Background:With the information office becoming more and more popular, people's office relies on the Internet more and more, it, the network in the enterprise's influence is more and more big. Therefore, the reliability of the enterprise network becomes very important. For an internet company or a company that needs to use a network to work properly, a broken network means that employees cannot work properly and the company has a lot of money to lose. In such a context, large companies and the f
