IPv6 anycast Technology and Its anycast Address Resolution Protocol Author: Wang Jianli fangwei Abstract: anycast is a new network application. Anycast communication supports service routing. However, many definitions of anycast communication in IPv6 are vague, and no pr

Anycast (anycast) refers to the communication between some of the closest receivers in the topology structure of any sender in a group. In comparison, multicast refers to a single sender corresponding to a group of selected receivers of a communication, unicast refers to a single sender of a single receiver of a communication.　　 Anycast is a method used to update

Practical Analysis of DNS multi-point deployment IP Anycast + BGP Most of the Multi-Point deployment in the DNS field uses the IP Anycast + BGP mode. In this mode, you do not need to purchase additional equipment, and the deployment is flexible and diverse. However, like all other technologies, IP Anycast + BGP technology can play its biggest advantage only in th

1. Introduction The anycast address is defined in the IPv6 address structure. It is defined as one or more network interfaces (usually different nodes ). If the packet is sent to the anycast address, it will be routed to the nearest interface with this address. What is the latest depends on the provisions of the routing protocol. Its application is still developing, but it is necessary for some importan

This article on the Anycast single site deployment, not to anycast related technologies do too much introduction, if necessary, please search the other documents.When deploying a single site, it may be necessary to involve the LVS Dr Mode to implement business anycast and unicast two types, where anycast is used as a s

Concepts of unicast, multicast, broadcast, and anycast UnicastIt refers to the unicast method in which the destination address is a single objective in the computing machine's website. It is the most widely used network today. Generally, most of the network recommendations or services used use unicast Protocol, for example, all TCP-based protocol. [Unicast features] Each time only two instances communicate with each other, the sender and accept

In the Nginx reverse proxy mode, the page loading is incomplete or the 502 bad gateway appears directly. There are many cases of 502 bad Gateway, most of which are related to the setting of the Nginx timeout problem. The following is a discussion of a situation that is relatively rare but has to be noted. Presence Environment Nginx work in reverse proxy mode, listening to non-80 ports (this is important

The gateway is used to control the flow of the process. The Gateway can consume or generate a token. The gateway is displayed as a diamond graph with a small internal icon. The icon indicates the type of the gateway. Basic Branch First, use process variables to write a basic process with branches Flowchart: Deploym

　　1, what is the gateway According to different classification criteria, there are many kinds of gateways. The gateway in the TCP/IP protocol is the most commonly used, where we speak of "gateways" that refer to the TCP/IP protocol gateway. What is a gateway? A gateway is e

Gateway-Gateway Protocol (GGP) To Route packets correctly and efficiently, the core gateway needs to know the situation of other parts of the Internet, including routing information and subnet characteristics. This type of information is usually used when a gateway processes heavy loads and is the only way to access th

You can try to clear the browser cache access to your FTP to see if you can log in Successfully resolved 502 Bad Gateway error Log on Today, show 502 bad Gateway,nginx the most annoying place is often this error, because I do not intend to spend too much time on the technology, so the general is encountered related problems, through the search engine solution can not go into the deep. Don't say much nonse

First, IntroBefore the gateway, many netizens concerned about how to implement the interface. To understand the change of the next machine variable, it is how to trigger the human-machine interface animation in one step.This step-by-step trigger is essentially a bulk data change (DataChange) event for the variable group (s), which raises the variable (TAG) value Update (ValueChange) event, which eventually triggers an animated script (Action) of the e

　　gateways (Gateway) are also called Network Connectors, protocol converters. Gateway on the transport layer to achieve network interconnection, is the most complex network interconnection equipment, only for two high-level protocols different network interconnection. Gateways can be used both for WAN interconnection and for LAN interconnection. A gateway is a co

You can try to clear the browser cache and access your FTP to see if you can log on Cause A server (not necessarily a Web server) serves as a gateway or proxy to meet customer requirements (such as a Web browser or our CheckUpDown robot) to access the requested URL. This server receives an invalid response from the upstream server to fulfill its requirements.Fixed 502 errorsGenerally, this problem is caused by poor communication between IP addresses o

Problem descriptionAfter initial troubleshooting, the application gateway itself works fine and also excludes the latency of the Azure platform network. The behavior that occurs is usually a partial URL response is normal, a partial URL response is slow, or HTTP Code 502 is returned.Problem analysis Determine application access and response by analyzing access logs (see: Backend Health, diagnostic logs, and metrics for application

Recently, server downtime occurs frequently. When I get off work, G crashes and 502 Bad Gateway Nginx reminds me of the previous 504 Gateway Time-out, the two should be in a certain relationship. Nginx 504 Gateway Time-out means that the requested Gateway does not have a request. Simply put, it does not have a request

How Spring Cloud Gateway worksThe client makes a request to Spring Cloud Gateway and, if the request matches the route defined by the gateway program, sends it to the Gateway Web handler, which runs a specific request-filter chain.The reason the filters are separated by dashes is that the filter may execute logic befor

1. Security gateway is an organic fusion of various technologies, with important and unique protection, ranging from protocol-level filtering to very complex application-level filtering. 2. The Business gateway is the gateway device connecting the business network and the Bearer network, which completes the function of the business Access layer in the architectur
