Eric,
EVS is guaranteed between multiple groups such that any message sent to
any group will be received at all receivers in the same order without
consideration of the groups abstraction. Groups are just an abstraction
built to ease the programming effort of separating messages meant for
different channels.
In your example, you could receive A first then B at all nodes, or B
first then A at all nodes, but never A,B at some nodes and B, A at
others. There is no way to guarantee "first to queue" (requesting the
protocol queue the message for transmission) since the protocol
guarantees ordering only on "origination" (sending the message via the
protocol) ordering. There is a time period between queueing and
originating, hence they are not the same operation.
Regards
