Abstract:
The User Datagram Protocol (UDP) provides a minimal message-passing
transport that has no inherent congestion control mechanisms. This
document provides guidelines on the use of UDP for the designers of
applications, tunnels and other protocols that use UDP. Congestion
control guidelines are a primary focus, but the document also
provides guidance on other topics, including message sizes,
reliability, checksums, middlebox traversal, the use of ECN, DSCPs,
and ports.
Because congestion control is critical to the stable operation of the
Internet, applications and other protocols that choose to use UDP as
an Internet transport must employ mechanisms to prevent congestion
collapse and to establish some degree of fairness with concurrent
traffic. They may also need to implement additional mechanisms,
depending on how they use UDP.
Some guidance is also applicable to the design of other protocols
(e.g., protocols layered directly on IP or via IP-based tunnels),
especially when these protocols do not themselves provide congestion
control.
This document obsoletes RFC5405 and adds guidelines for multicast UDP
usage.
