Linux Socket Programming

• Sockets allow communication between two different processes on the same or different machines.

• A socket is just a logical endpoint for communication. They exist on the transport layer.

• TCP socket

  • Type: SOCK_STREAM
  • reliable delivery
  • in-order guaranteed
  • connection-oriented
  • bidirectional

• UDP socket

  • Type: SOCK_DGRAM
  • unreliable delivery
  • no order guarantees
  • no notion of “connection” – app
  • indicates destination for each
  • packet
  • can send or receive
