CEF (Cisco Express Exchange) detailedCEF Load BalancingOne, the destination-based balance of responsibility:Destination-based load balancing allows routers to use multiple paths to balance the load. For a source/target host, packet forwarding takes the same path, which is handled even if multiple paths are available. D
A mention of load balancing, I believe many students will directly think of nginx reverse proxy, because we are usually more familiar with Nginx to do Web services load balancing. In fact, Nginx is only part of the load balancer, and each level in the Web application actuall
Objective:
With the explosive growth of Internet information, load balancing (loading balance) is no longer a very unfamiliar topic, as the name implies, load balance is to spread the load to different service units, not only to ensure the availability of services, but also to ensure that the response fast enough to g

Disclaimer: This article is reproduced.When a server (including Web servers, FTP servers, or streaming media servers, etc.) is put into the network, as the number of clients increases, people often need servers that are more powerful and processing faster. To solve this problem, it is obviously not a good idea to replace the original server with a more powerful, faster server. But if you can add a new server to the processing power of the original server instead of replacing it, this scheme is u

To improve server performance and workload, enterprises usually use DNS servers, network address translation, and other technologies to achieve multi-server load balancing, many of them use several servers to achieve Load Balancing for server access.
Currently, the so-called "Server

In general, load balancing is the client's request to the backend of the various real servers to achieve load balancing purposes. There is another way is to use two servers, one as the primary server (master), the other as a hot Standby, the request is all to the primary server, when the pr

In some cases, the expansion is obvious, such as the download service due to insufficient bandwidth and must be extended, but, other times, many people see the site performance is not satisfactory, immediately implement load balancing and other expansion means, really need to do this? Of course, the problem is only their own to answer, in addition to high availability and deployment considerations, in most

Load balancing, also known as load sharing, refers to load balancing by dynamically adjusting the load on the system, and performing the load on multiple operational nodes to reduce the
number of users that can be supported by the cluster system and the time required to process a request.
Among the many existing methods of balancing server load, the following two methods are widely studied and used:
