The Multicast Application Port
This document discusses the drawbacks of the current practice of
assigning a UDP port to each multicast application. Such assignments
are redundant because the multicast address already uniquely
identifies the data. The document proposes assigning a UDP port
specifically for use with multicast applications and lists
requirements for using this port. This approach provides immediate
compatibility with existing protocol stacks, while also requiring
improvements to make the port easier to use.
