Match module
D ESCRIPTION
The Match module brings together a specified number of entities waiting in different
queues. The match may be accomplished when there is at least one entity in each of the
desired queues. Additionally, an attribute may be specified such that the entities waiting in
the queues must have the same attribute values before the match is initiated.
When an entity arrives at the Match module, it is placed in one of up to five associated
queues, based on the entry point to which it is connected. Entities will remain in their
respective queues until a match exists.
Once a match exists, one entity from each queue is released to be matched. The matched
entities are then synchronized to depart from the module.
