I am unsure how you would encode a DDOS using sighting in this manner without duplicating the network connection, can you give an example?

Hi all
I have some questions about the network flow object.
----
The first is about the multiplicity of the source_refs.
Multicast traffic always so comes from a single source. So does a network broadcast. So is there any reason to have the source as a list when there is always just one source? Am I missing something?
We should really change its name to src_ref, and restrict it to one object-ref.
----
The second is around the list of options in the protocols field. We should probably provide an open vocabulary taken from both the IANA protocol list and the IANA services list to provide people a list of common options they should use. Otherwise we'll hit problems like people putting in 'ip' rather than ipv4 or ipv6, which is ambiguous.
