tcp load balancer

MAC address of the destination in the datagram, it decides to send the datagram to the next place. The 3rd layer switch is also called a "Router", and the work done by the 3rd layer switch is called a "Route ". Server Load balancer is located at Layer 3, or layer 4th, layer 5th, and layer 6th. The request Forwarding is determined by viewing the data packets sent to these layers.

the current status, migrate to the next status. The TCP State migration of VS/DR is performed according to the semi-connected TCP finite state machine. Virtual Server (VS/TUN) through IP tunneling) Similar to VS/DR, VS/TUN is an asymmetric feature of most Internet services. The Server Load balancer only schedules req

can implement some shunting policies for http applications, such as targeting domain names and directory structures;2. Nginx has little dependence on the network. Theoretically, it can be pinged to implement the load function;3. Nginx installation and configuration are relatively simple and easy to test;4. It can also handle high load pressure and stability. Generally, it can support more than 10 thousand

. Both the WEB and the WEB are connected to that database, so that the two WEB contents are synchronized, then load the two WEB servers. below is my COPYNetwork Load Balancing allows clients to access the cluster with a logical Internet Name and virtual IP address (also known as the cluster IP address), while keeping the names of each computer. Next, we will introduce the implementation and application of n

Recently want to be able to configure load balancing, in the virtual machine above, but the Internet to find a lot of information is fragmented, for people who do not know, a lot of not enough detail, recently finally done, the specific steps to write down, convenient for you to read the studyThis experiment requires the installation of Nginx if not installed, please refer to:Linux installation nginx:http://www.cnblogs.com/aspirant/p/6714548.html(1) O

Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup; Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

Nginx Server Load balancer configuration instance details, nginx Server Load balancer instance First, let's take a brief look at what Server Load balancer is. Simply understanding what it means literally can explain that N servers

The server Load balancer described in this article is used to balance client requests among multiple nginx processes. Note the difference between Server Load balancer and client requests on multiple backend servers. The problem of Server Load

Apache + Tomcat server Load balancer configuration and tomcat server Load balancer Apache + Tomcat server Load balancer ensures high availability and system performance, which is achieved through communication between Apache and

Five Policies for configuring Server Load balancer using nginx in the production environment: nginx Server Load balancer Nginx upstream currently supports five allocation methods1. Round Robin (default) Each request is distributed to different backend servers one by one in chronological order. If the backend servers ar

Both LVS and Nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to

Nginx Server Load balancer transmits the parameter method to the backend (the backend is also an nginx server), and nginx Server Load balancer A website uses nginx for load balancing and multiple nginx servers at the backend. Encountered a problem, when it is used as SSL sup

converted between the internal address and the external address so that computers with the internal address can access the external network, when a computer in an external network accesses an external address owned by the address translation gateway, the address translation gateway can forward it to a mapped internal address. Therefore, if the address translation gateway can evenly convert each connection to a different internal server address, then the computers in the external network will co

requirements, in addition, line upgrades are too expensive or even difficult to implement. In this case, we can consider using the trunking technology. Link aggregation technology (Layer 2 load balancing) uses multiple physical links as a single aggregation Logical Link. network data traffic is shared by all physical links in the aggregation Logical Link, this increases the capacity of the link logically so that it can meet the demand for increased b

can be achieved [2]. In reverse proxy mode, you can apply the optimized load balancing policy to access the idle internal server each time to provide services. However, as the number of concurrent connections increases, the load on the proxy server itself becomes very large, and the reverse proxy server itself becomes a service bottleneck. In the address translation gateway that supports server
