...We can apply the same pattern to read and write structured responses through a JSON encoder and decoder.Zero-copy upgrade helps to avoid unnecessary allocations and copying while handling HTTP Upgrade request.
A Header-Only cross-platform C++ TCP network library
Header Only Cross-platform high-performance TCP network library using C++ 11. The server uses two network threads and one logic thread, the client uses one network (also process logic) thread. Every packet size is 46 bytes. Every packet contains the client's id. Server broadcast packets to all clients when recv one packet from any client. The client sends one packet when recv packet from the server and the packet's id is equal self.
Lightweight application-protocol for devices that are constrained their resources such as computing power, RF range, memory, bandwith, or network packet sizes. This protocol, CoAP, is developed in the IETF working group "CoRE", <http://6lowapp.net>.
