The Network Library

The network library in C++23 is based on the boost::asio library from Christopher M. Kohlhoff. The library targets the network and low-level I/O programming.

The following components are part of the network library:

• TCP, UDP, and multicast
• Client/Server applications
• Scalability for more concurrent connections
• IPv4 and IPv6
• Name resolution (DNS)
• Clocks

However, the following components are not part of the network library:

• Implementation of network protocols such as HTTP, SMTP, or FTP
• Encryption (SSL or TLS)
• Operating specific multiplexing interfaces, such as select or poll
• Support for realtime
• TCP/IP protocols like ICMP

Thanks to the network library, you can directly implement an echo server.
