multi wan load balancing

technology to actively detect each node.In most LAN-based clusters, the fastest response algorithm does not work well, because ICMP packets in the LAN basically respond within 10 ms, which does not reflect the differences between nodes; if a balance is made on the WAN, the response time is of practical significance for the user to select the server nearby. In addition, the more scattered the cluster topology, the more effective the method can be. Thi

Not long ago I was in charge of a well-known national manufacturing group's load balancing project. I was deeply touched by the project's application of gslb in a specific environment and learned a lot of related Load Balancing knowledge. Today, let's calm down and think about how to learn a lot through the project. du

Load BalancerIt can be a dedicated device or an application that runs on a common server. Distribute requests to servers that have the same content or provide the same services. Special purpose devices are generally only Ethernet interfaces, which can be said to be a multi-layer switch. The load balancer is typically assigned a virtual IP address, and all request

, not the difference between the nodes, if the balance on the WAN, the response time for the user to choose the nearest server is of practical significance , and the more dispersed the cluster topology, the more effective the method can be. This approach is the primary approach to advanced balancing based on topology redirection.3. 6 Weighting methodWeighted methods can only be used in combination with othe

With the decline in computer hardware prices and the development of computer network topology, distributed computer systems provide users with a rich set of resources. When studying distributed systems, people have noticed the following problem: in a network-Connected Multi-computer environment, some computers have heavy load at a certain time, the load on other

Supports fail-fast recovery, which automatically recovers the cluster online when a server fails to restart. Support for unicast, multicast, IGMP multicast multiple cluster operation modes. Support Event log management to quickly review cluster event records. Iii. how NLB is used3.1.

In multi-core CPUs, it is important to ensure that the tasks assigned to each CPU have a good load balance in order to perform the performance of multiple CPUs well. Otherwise, some CPUs are running, others are idle, and they are not able to perform the benefits of multicore CPUs. To achieve a good load balance there are usually two scenarios, one is static

, the user's CGI program is responsible for tasks that avoid location loops.2. DNS-based load balancing (multi-host Single Domain Name load)Server Load balancer Based on server software needs to change the software, so it is often not worth the candle. Server

application image contains all the parts required for a business solution, including WEB sites, registry settings, files, COM + components, and so on. By reflecting the current state of the cluster's events, performance counters, and monitors, it is easy to monitor the operation of the cluster. Application Center Cluster With application Center, you can build multi-level clusters that can use a variety of load
