Today, I saw an exciting message on the Google App Engine blog: "Today, we're adding the same service (Google over IPv6) to all domains hosted by ghs.google.com ." What does this mean? You should have thought about it. Especially the miserable blogger in mainland China. The new GHS cname domain name deployed by Google is ghs46.google.com. In view of the IPv6 support provided by Windows Vista and Windows 7, you can modify the hosts file. A script is specially posted here today, this functio

, the method of implementing virtual server through IP tunneling Vs/tun (virtual server via IP tunneling), and the method of implementing the dummy server through direct routing vs/dr Server via Direct Routing), which can greatly improve the scalability of the system. Therefore, the Ipvs software implements these three kinds of IP load balancing techniques, and their approximate principles are as follows.1,

of network service, we propose the method of implementing virtual server through IP tunneling Vs/tun (virtual server via IP tunneling), and the method of implementing the dummy server through direct routing vs/ DR (Virtual Server via Direct Routing), which can greatly improve the scalability of the system. So, Ipvs Software realizes these three kinds of IP load balancing technology, their approximate princ

non-standard ports;Real servers in the background can use any operating system;The director may become a system bottleneck. b) Vs/tun: i.e. (Virtual Server via IP tunneling) Virtual server is implemented by IP tunneling technology. Its connection scheduling and management is the same as the Vs/nat way, but its message forwarding method is different, Vs/tun mode, the Scheduler uses IP

Instead, it relies on IP tunneling technology. IP tunneling (IP tunneling) is the technique of encapsulating an IP message in another IP packet. In

This waiter is the load balancer (LB) and these are the server clusters that are really doing what's behind.Below is the structure chart provided by the official website:The basic working process of LVSThe customer sends a request to the Load Balancer server. The load balancer accepts requests from customers and then decides which node server to send this request to, based on

. However, the LVS architecture has certain scalability, which can achieve high performance, high scalability, and ease of management among other features, and become a truly meaningful Cluster System with load balancing as the core. First, let's take a look at the LVS load balancing model. There are three types: address translation (NAT), IP tunneling (IP tunneling), and direct routing (DR) models. ◆ Addre

. The system realizes relatively simple, it does not need the complex pattern matching mechanism, it is mainly through the port mapping for the data exchange, the rule is simple, compared with the content based high-level exchange. Next, we will analyze the LVS framework and implementation method based on load balancing technology. Back to the top of the page IP load Balancing technology of LVS Fundamentally, the implementation of LVS is based on IP switching, which is the aforementioned acces

subnet IP address segment, This is where it solves the problem of IP address assignment, which, once assigned to Docker Deamon, allows Docker demon to assign IP to the container. The second problem is how to implement a cross-host packet exchange, which is done through a three-tier route: As with traditional practices, all containers are connected to the Docker0, and a Flannel0 virtual device is inserted between the DOCKER0 and the host card. This virtual appliance provides a lot of flexibility

The monitoring system has made new breakthroughs in the wireless age, especially in China. Our country has a complex terrain and a vast territory. We want to monitor tunnels in such a complex environment, wired monitoring is always limited, so the birth of the wireless monitoring system has injected fresh blood into the monitoring system. In the Monitoring System Application of the tunneling industry, the solution represented by the current wireless m

According to the layered model, VPN can be established on the second layer or on the third layer (some even classify some higher-level security protocols into VPN protocols .)

then triggers the reaction, just as the key rotates the lock. This is a delightful, very intuitive doctrine, but it does not explain certain phenomena-for example, molecules with similar shapes often smell differently and vice versa. The revised doctrine argues that receptors may be reacting to molecular vibrations. In the 1996 the idea was further explained at the quantum level--a physicist Luca Du (Luca Turin) suggested that vibrations might promote the quantum
