0. Benefits of dynamic Upstream Openresty author, recently also open source (not open source when I write this article) they have used the Balancer-by-lua feature, progress issues. Can dynamically modify the upstream, using reverse proxy proxy_pass, to the back-end process or machine: dynamic load balancing control; smooth up and down service, upgrade service; High possible guarantee – Auto kick offline se

The past year due to work, has been busy, there is no time to update some ISP algorithm, after a year of efforts, their own ISP algorithm also has a deeper understanding, so decided to recently to the ISP algorithm to share some of the understanding, for everyone to reference the study, hope to engage in this line of people useful.This paper mainly introduces one

Related Configuration The nginx upstream persistent connection is controlled by the keepalive command in upstream mode and specifies the number of connections that can be used for persistent connections. The configuration example is as follows: upstreamhttp_backend{ server127.0.0.1:8080; keepalive 16; } server{ ... location/http/{ proxy_passhttp://http_backend; proxy_http_version 1.1; proxy_set_header

Analysis of demand and application of microwave trunk access for ISP group usersThe Computer network communication protocol is TCP/IP;Provide at least >64kbps data communication rate;Network isolation is implemented by the local router;Establish a Level two network, select the users with better geographical conditions to establish a secondary center to meet the requirements of user access within the metropolitan area;The omni-direction antenna can be

The five principles of OO refer to SRP, OCP, LSP, DIP, ISP.Open Closed Principle is the most basic design principle in the Java world, which guides how we build a stable and flexible system.Defined:A software entity such as classes, modules, and functions should be open to extensions and closed for modification.Softeware entities like classes,modules and functions should is open for extension but closed for modifications.The opening and closing principle means that a software entity should be ex

Interface isolation principle (ISP): it is better to use multiple special interfaces than to use a single total interface. The dependence of a class on another class should be based on the smallest interface. An interface represents a role, and different roles should not be assigned to an interface. Unrelated interfaces are merged to form a bloated large interface, which is a pollution to roles and interfaces. Synthesis/aggregation Reuse Principle (C

I asked everyone to test 1.5 last time. After four days, I had a good news. Now, I have handled some problems in the use of 1.89 in 1.5, which further ensured that the blacklist is free. It can be said that after five days of testing, the tool without blacklisting has been fully successful, and the software can run on the Internet starting from 1.89. In this way, no special computer is needed to run the tool. The new Wan Port Extension tool allows users to easily implement VLAN connection and

], the enhanced channel, the second step to obtain the global white balance.The third step: to solve the optimization problem, the ACE algorithm can be regarded as a smoothing and local correction method for the normalized histogram equalization method.Some of the factors considered in the improvement approach are:1) Other slope function SA (t), polynomial function approximation2) In addition to 1/| | x-y| | The selection of the weight function outside3) in the summation process, Y can be limite

Unless you use Telnet to the software logon ISP's server, you are not able to connect the database via DSN. Here are a few ways to connect you beyond your ISP and make it easy to connect to your database: 1.SQL Server CStr = "PROVIDER=SQLOLEDB; Server=CStr = CStr "network=dbmssocn;uid=Set conn = Server.CreateObject ("Adodb.connection") Conn.Open CStr ' Connect with NETWORK=DBMSSOCN to avoid errors caused by admin naming %> 2.Oracle CStr = "provider=o

If the interface of a class is not cohesive, it means that the class has a "fat" interface. In other words, the "fat" interface of a class can be decomposed into multiple sets of methods. Each group of methods serves a different set of client programs.The ISP acknowledges that some objects do need to have non-cohesive interfaces, but ISPs recommend that the client program should not see them as a single class presence. Instead, the client program shou

ICP means "in circuit programming" (in circuit programming), PC computer can run "NuMicro ICP programming Tool" software via Nu-link SWD interface (serial wir e Debug) To update the target board on the Aprom, Ldrom, Data Flash and user config word.The ISP means "in system Programming" (in Systems Programming), the target board calls the external interface by running the boot/load code in Ldrom, such as USB/UART/SPI/I2C ...

This programming is a dynamic modification of the Code executed by the program, and does not require any external force or any mechanical operation. This is different from ISP.Generally, the ISP needs to set some

Introduction to upstream polling mechanism in Nginx In Nginx, upstream has the following methods: 1. Round Robin (weight = 1)By default, when weight is not specified, the weight of each server is the same, and each request is allocated to different backend servers one by one in chronological order. If the backend server is down, it can be automatically removed. Upstream
