property Proto: String;


Proto defines the protocol to be used by the socket. The following protocols are available:

  • TCP - a connection oriented protocol with automatic retransmission of lost packets (at least to a certein degree)
  • UDP - a fast and connectionless protocol but without retransmission of lost packets and packets may be dropped if network load is high. The overhead is much less than with TCP so it is suited for real time audio/video transmission
  • RAW - socket without overlaying (UDP/TCP) protocol. Warning: using RAW sockets requires administrator privileges in Windows 7 (exception: ping which is also based on raw sockets internally)


Best practices

  • Avoid using RAW sockets where possible, as they require administrator privileges in newer Windows versions
