 Cppnet is a proactor mode and multithreaded network with C++11 on tcp. Support Window, Linux and macOS.    
  Simple:    
- + only export a little interfaces, all net ios insterface are asynchronous callbacks
- + insterface as much as possible like calling the socket API of the system
- + there is only one additional buffer object type for the client
+ + Only export a little interfaces, all net ios insterface are asynchronous callbacks
+ + Insterface as much as possible like calling the socket API of the system
+ + There is only one additional buffer object type for the client
+ + Support both IPv4 and IPv6
 
  Fast: 
- + epoll, IOCP and kqueue are used
- + multithreaded threads are handled by the kernel through port reuse
- + each socket has a single memory pool object. All memory requested from the memory pool is managed by an intelligent pointer 
- + using time wheel to realize timer

  Clear：
- + three layers: event-driven layer, session management layer and interface layer
- + upward notification through callbacks between layers. Clear division of responsibilities among modules, pay to Caesar what belongs to Caesar and God what belongs to God
- + the interface decoupling module is used to meet the minimum interface principle and dependency inversion principle
