eigrp load balancing

The load master can provide many kinds of load balancing methods, that is, we often call the scheduling method or algorithm:Round robin (Round Robin)This method loops the received requests to each machine in the server cluster, which is the active server. If this is the case, all the servers that are tagged into the virtual service should have similar resource ca

When the vertical expansion of the Web server becomes expensive or difficult, we need to consider the level of server expansion, namely load balancing technology. There are many techniques for load balancing, which we'll cover here.1.HTTP redirectionWe can do this at the code level by setting access to specific pages s

Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source

are many things to do. The Nat mode is simple, that is, to change the IP address and port information to the IP address and port of the real balancing machines, so that the real service machines are hidden behind the Load balancer, the idea is the same as that of normal Nat.[Tunnel mode]: The tunnel mode is to repackage data into a new IP data packet, and then send the data to the virtual Nic by modifying

JBOSS via Apache Load Balancing method one: Using MOD_JKIn the first to second section of this article, we use Apache in the Linux environment and the front end of Windows to realize load balancing using IIS through AJP protocol and back-end jboss communication, and the corresponding parameters are explained in the thi

29.13 common access redundancy protocol (CARP, shared address redundancy protocol) Original Tom Rhodes. Common Access redundancy protocol, or carp for shortAllows multiple hosts to share the same IP address.Address. In some configurations, this can improve availability or achieve load balancing. In the following example, these hosts can also use different IP addresses at the same time.Address. To enable Car

Today, the ' big server ' model is over, replaced by a large number of small servers, using a variety of load-balancing techniques. This is a more feasible way to minimize the cost of hardware. The advantages of ' more small servers ' over the past ' large server ' model are embodied in two aspects: 1. If the server is down, then the load-

Nginx Version: 1.9.1 Algorithm Introduction Consistent hashing algorithms are often used to load balance when the backend is a caching server. The advantage of using a consistent hash is that when you add or subtract a clustered cache server, only a small amount of caching is invalidated and the source is smaller. In Nginx+ats/haproxy+squid and other CDN architectures, the load

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. The load balancing capability is the main feature of a single WAN p

To solve the problem of complex balancing, MySql officially launched the MySql Cluster architecture, the following describes the feasibility of five MySql Server clusters in terms of basic conditions, costs, advantages and disadvantages, and application scenarios: 1. MySQL Clustering (ndb-cluster stogare) The high-reliability solution provided by MySQL in the form of storage engines is transaction-safe, real-time data replication, and can be used in s

In this paper, the basic reference from the easy implementation of APACHE,TOMCAT cluster and load balancing, through the actual experience recorded, encountered some discrepancies, as well as individual places according to personal habits, so to a certain extent failed to maintain the integrity of the original, but also hope that the original Haihan.Because there are more stickers in the original text, if y

determines that the transmission is based not only on the MAC address (the second Layer Bridge) or the source/destination IP address (third-tier routing), but also on the TCP/UDP (layer fourth) application port number. Layer Fourth switching functions are like virtual IP, pointing to the physical server. It transmits a variety of business compliance protocols, with HTTP, FTP, NFS, Telnet, or other protocols. These services require a complex load

Site architecture (page static, image server separation, load Balancing) scheme full analysisArticle Category: Integrated technology1, HTML Static in fact, we all know that the most efficient, the least expensive is the pure static HTML page, so we try to make the page on our site using static pages to achieve, the simplest method is actually the most effective method. But for a lot of content and frequentl

: This article mainly introduces load balancing for Nginx + Tomcat. For more information about PHP tutorials, see. Nginx load balancing Recently, the project has to be designed with concurrency. Therefore, when designing the project architecture, we should consider using Nginx to build a Tomcat cluster and using Redis

Load balancing is to increase the overall performance by allocating the load evenly to each node in the cluster. Oracle RAC provides two ways to achieve load balancing, the following is a detailed introduction, the need for friends can refer to the next Oracle RAC provides

medium and large projects will take into account the distribution, the previous several articles focused on the technical cluster of data processing. Let's look at the load balancing –nginx for servers today. He can also decide to place the request on that service, in addition to the static resource processing. installation of Nginx Point I download the download well, we can directly click to open the serv

CentOS Apache-based Tomcat load balancing and clustering First, the background principle1, Tomcat to do a Web server has its limitations, low processing power, low efficiency. withstands concurrency Small (around 1000). However, there are many websites or pages that are JSP. And the use of Tomcat as the web, so only on this basis to increase the optimization.2, the current approach is the Apache + MOD_JK +
