The Internet Data News Agreement (IDP) is a simple unreliable datagram protocol, mainly used to support SOCK_DGRAM abstraction concepts for the Internet Protocol (IP). IDP sockets are unconnected, usually applied to Sendto and Recvfrom subroutines. The connector can also be used to secure the destination for future data packets, in which case the RECV or READ subroutine and the Send or WRITE subroutine can be used.
The Xerox protocol (XNS protocol group) is set vertically on the IDP, so the IDP address format is the same as the format used by the Sequence Group Protocol (SPP: SEQUENCED PACKET Protocol); the port space is the same, that is, if a specific option is available, IDP port You can "connect" to the SPP port. In addition, by reserved broadcast addresses, the broadcast data packet (assuming the underlying network supports the operation), where the address refers to the network associated interface.
