With the development of information construction in various industries, people put forward higher requirements for the processing ability and high availability of the network server. Especially in highly information-based enterprises, the key network services have become an important part of enterprise generation process, interruption of service means the interruption of production and the loss of opportunity. Load
In the contact load balancing, the author first in the Network Load Balancing search, figuring out what is load balancing, and then found that support load
Citrix NetScaler Load Balancing algorithmhttp://blog.51cto.com/caojin/1926308As we all know, Citrix NetScaler, which delivers products as a new generation of applications, has the industry's leading data control, application delivery capabilities, but as one of the fundamental content of ADC capabilities, it is not possible to adapt to so many scenarios without a robust, diversified equalization algorithm I

Today, we are going to introduce NLB, Network Load BalancingNetwork Load Balancing, referred to as NLB, allows you to propagate incoming requests to up to 32 servers, which means you can use up to 32 servers to share external network request services. Network Load Balancing
I. NLB test environmentSet up an NLB experiment environment as shown in 1. The computer Server is a domain controller and DNS Server, the client and client2 are member servers, and the domain name is ittongluren.com. The IP address of all computer gateways is 192.168.0.1, and the preferred IP address of the DNS server is 192.168.0.2. 2nd NICs are installed on the computer server and client for connection between nodes. The IP address of the network load
Windows Apache does load balancing The first time I saw this headline I was surprised that Apache can still do load balancing? It's so powerful. After a survey found that it can, and the function is not bad. This is thanks to the Mod_proxy module. Is worthy of the mighty Apache AH. Less nonsense, the following is to
Three, load Balancing algorithmCommon load balancing algorithms include, polling, random, least link, source address hash, weighting, etc.3.1 PollingDistribute all requests, in turn, to each server, which is appropriate for the same scenario as the server hardware.Advantage: The number of server requests is the same;Di
Summary : For a large web site, load Balancing is an eternal topic. With the rapid development of hardware technology, more and more load balancing hardware devices emerge, such as F5 big-IP, Citrix NetScaler, Radware and so on, although can solve the problem, but its high price is often prohibitive, So
In many existing network applications, sometimes a server cannot meet the requirements of the client. In this case, you can only add servers to solve the problem. Is there a way or technology to solve this problem? Use the network load balancing cluster in Windows 2000 or Windows Server 2003 (This article describes how to implement the Network Load

1: HTTP redirection The so-called HTTP redirection is to identify the new URL by modifying the location in the HTTP Response Header, and then return it to the client, so that the client can make a new request based on the URL identified by the location. This is the simplest and most lightweight Load Balancing implementation solution. We can use Asp.net to implement it like this. For example, in the main
Multi-core CPU, to play a good performance of multiple CPUs, you must ensure that the task assigned to each CPU has a good load balance. Otherwise some CPUs are running, others are idle and cannot play the advantage of multi-core CPUs. There are usually two scenarios for achieving a good load balance, one is static load bala

From: http://hi.baidu.com/_kouu/item/479891211a84e3c9a5275ad9 In an SMP (symmetric multi-processor) Environment, each CPU corresponds to a run_queue (executable Queue ). If a process is in the task_running state (executable State), it will be added to one of the run_queue (and will only be added to one run_queue at the same time ), so that the scheduler can schedule it to run on the CPU corresponding to run_queue.A cpu corresponds to a run_queue design, which has the following advantages:1. A pr
Under the condition that the price of computer hardware declines and the network topology develops, distributed computer system provides a rich collection of resources for users. When people study distributed systems, they notice a problem: In a multiple-computer environment connected by a network, at a certain point, some computers load more heavily, while others are lighter. Balancing the
