array networks load balancer

The current development trend of the website for the use of network load balancing is as the scale of the website increases according to different stages to use different technologies:One is through hardware. Common Hardware includes expensive NetScaler, F5, radware, array, and other commercial load balancers, it has the advantage of a professional maintenance te

systems or different hardware. For example, a cluster that provides Web Services is a large Web server. However, cluster nodes can also provide services separately.3. Features: based on the existing network structure, Server Load balancer provides a cheap and effective method to expand server bandwidth and increase throughput, enhance network data processing capabilities, and improve network flexibility an

project, cost-effective is much higher than F5, commercial first choice! But in general this phase of the relevant talent to keep up with the business, so the purchase of commercial load balance has become the only way. The ability and quantity of talent is also increased, at this time, regardless of the development of customized products for their own, and reduce the cost of open source LVs, has become the first choice, then LVS will become the main

Summary: For a large website, Server Load balancer is an eternal topic. With the rapid development of hardware technology, more and more Server Load balancer hardware devices are emerging, such as F5 big-IP, Citrix NetScaler, and radware, however, the high price is often prohibitive, So

QoS function, the router provides different levels of priority processing capabilities for data exchange for specific business applications.　　3. Use layer-4 switching technology to achieve server load balancingThe following design comes from the practical application of the network center of a Network Education College in a university. The layer-4 switch of Alteon provides Server Load

to modify client and server-side programs. To do this, you need to consider system transparency, scalability, high availability, and manageability at design time.650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M01/80/4B/wKioL1c9eDvBFVmAAAB49gJNA28736.png "title=" 00.png "alt=" Wkiol1c9edvbfvmaaab49gjna28736.png "/>The LVS cluster adopts three-layer structure and its main components are:1) Load Scheduler (B
