Detailed Description

This is an implementation of the User Datagram Protocol described in RFC 768.

It implements a connectionless, unreliable datagram packet service. Packets may be reordered or duplicated before they arrive. UDP generates and checks checksums to catch transmission errors.

The following options are not presently part of this implementation: UDP_CORK, MSG_DONTROUTE, path MTU discovery control (e.g. IP_MTU_DISCOVER). MTU handling is also weak in ns-3 for the moment; it is best to send datagrams that do not exceed 1500 byte MTU (e.g. 1472 byte UDP datagrams)
