packets into small data segments and distribute them to multiple parallel lines. It can also dynamically allocate dialing lines based on the current Link Utilization. Although the speed is very slow, because packet segmentation and additional buffering increase latency, it can run well on low-speed lines.The link aggregation system increases the complexity of the network, but also improves the reliability of the network, so that people can use redundant routes on the lines of key LAN segments s
front-end is the Server Load balancer, which is responsible for distributing various service requests to the subsequent physical servers, so that the entire cluster is like a virtual server serving the same IP address.3. Operating Principles and advantages and disadvantages of LVS: Linux virtual server is mainly implemented on the server
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
I. Introduction of LVSLVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. LVS is a TCP/IP-based load balancing technology that has high forwarding efficiency and the ability to process millions of concurrent connection requests.The IP
is a virtual IP address of keepalived. It is an external public IP address and also an IP address pointed to by DNS. Therefore, when designing the website architecture, you must apply for an external IP address from your IDC. 11. during actual project implementation, we found that LVS and nginx have excellent support
, the communication volume is moved to another host. Network Load Balancing Configuration OverviewNetwork load balancing is a network driver for Windows 2000. Its operations are transparent to TCP/IP network stacks. To ensure optimal network performance, network load balancing usually uses a network adapter to handle c
F5 is one of our most popular Server Load balancer products, so here we will introduce its configuration on the actual business platform. Through this case, I hope you will have a clear understanding of the specific use and configuration of this product. For more information, please refer to the following section.I.

Based on the huge network structure, the use of cluster servers brings a lot of traffic and other load problems. In contrast, Server Load balancer technology has also emerged. Every technology requires Product Support. Now let's get to know one of F5 Server Load balancer. Fi
Nginx/lvs/haproxy is currently the most widely used three load balancing software, the general use of load balancing with the increase in the size of the site according to different stages of the use of different technologies, specific application needs to be specific analysis. if it is a small and medium-sized Web application, such as the day PV less than 10 million, with Nginx can be completely, if a lot
After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely. Background: Use Nginx and two Tomcat servers to achieve load balancing, disable tomcat ports (8080 and 8090) in the firewall, and open only port 80 to the
Ningx acts as a Load balancer and is also a reverse proxy server. The configuration syntax is quite simple. It can be used to balance the backend servers by round robin, IP_hash, url_hash, weight, and other methods, it also supports backend server health check. In addition, it has advantages over LVS because it is based on Layer 7 Server Load
