An easy-to-learn, high performance network io library written in modern cpp (c++11), It borrows concepts from Netty, and with well defined internal modules, It enables you to write rpc, http/https,websocket application with just few lines。

Last update: Dec 15, 2022

Overview

A new beginning of network programming

What is Netplus

Netplus is a network programming library written in c++11. It's highly extensible, and with default configuration it can reach high performance. It's easy to learn. Basically, you can just implement your own business in a channel handler, then the library would do all the dirty work (platform specific considerations, io event delivery&process, basic memory optimization, etc ) for you. You can also write http/https,websocket,based application even you only have little corresponding knowledge background, Cuz it has relevant modules to simplify programming tasks of such kinds. Netplus borrows lots of concepts from Netty, and tries to implement these concepts by c++, such as channel, channel handler, channel pipeline, executor, scheduler, promise. Any one who is familiar with Netty should be able to start with ease.

What can we use Netplus to do

1) Implement a message gateway
2) Use as the network component of a message queue, gameserver or any other network based application.
   please note that netplus is not a gameserver framework, But you can implement one with netplus
3) Implement protocol driver of Middleware, such as kinds of database, message queue server, etc
4) Implement http/https, websocket based application
5) Implement RPC server

Target Arch & Platform

1) Windows on x86
2) Linux on x86/arm
3) IOS/MAC on x86/arm
4) Android on x86/arm

rpc: optimize request list

1, We have to check the requested call and see whether the request has expired a duration. 2, For each reply from server, we have to lookup through a container (list for now) to get the original request call

Right now, we use a requested list to achieve the above goal, the lookup cost is o(n), It might be better to optimize the list to a hash based circular buf.

socket_channel: check whether a sendmsg with multi-buf has a better performance compared to send

In case there are n buf to be sent, if we could merge it together, we could save n-1 system call(send), There are two ways to achieve the goal . 1, copy n buf into 1 buf, then call send 2, use sendmsg with iov

We have to schedule a bench and make a choice.
