1. Overview To improve network performance optimization, it is very important to reduce latency and improve response speed. Usually, when we make a request in the browser, the header part is like this Keep alive is to keep a long connection between the browser and the server, which can be reused. It is enabled by default in HTTP 1.1. Why does ...

1. What is RPCRPC is a way of communication between processes, the full name is "remote call procedure".When a client sends a request to the server, it is not sent directly to the target server, but to the RPC Server, which schedules it.RPC provides remote calling methods that are no different from calling local methods. 2. Introduct ...

NIO—NonBlocking IO(new IO) io flow oriented programming can only be used as one of the input or output flows. It is synchronous blocking. Every connection needs to create a thread to handle. The thread context switching overhead is very large, which creates a big bottleneck So the pseudo blocking IO implemented by thread pool solves the proble ...

introduction Go builds a simple and high-performance native network model (I/O multiplexing netpoll based on go) based on I/O multiplexing and goroutine, which provides a simple network programming mode such as goroutine per connection. In this mode, developers use the synchronous mode to write asynchronous logic, which greatly reduces the ment ...

11.2.1.2 find service information In addition to the IP address, each socket address includes an integer port number. Many applications can run on the same host and listen to an IP address, but only one socket can use the port of that address at a time. By combining IP address, protocol and port number, a communication ...
