on an entity before the second server is available, the entity must stay in the first server
past the end of service and the first server cannot accept a new entity for service until the
second server becomes available.
Parallel Queue-Server Pairs as Alternatives
Two queue-server pairs connected in parallel, in which each entity arrives at one or the
other, represent alternative operations. For example, vehicles wait in line for one of
several tollbooths at a toll plaza.
Parallel Queue-Server Pairs in Multicasting
Two queue-server pairs connected in parallel, in which a copy of each entity arrives
at both, represent a multicasting situation such as sending a message to multiple
recipients. Note that copying entities might not make sense in some applications.
