Definition of A BCMP Network
A network of m interconnected queues is known as a BCMP network if each of the queues is of one of the following four types:
- FCFS discipline where all customers have the same negative exponential service time distribution. The service rate can be state dependent, so write for the service rate when the queue length is j.
- Processor sharing queues
- Infinite server queues
- LCFS with pre-emptive resume (work is not lost)
In the final three cases, service time distributions must have rational Laplace transforms. This means the Laplace transform must be of the form
Also, the following conditions must be met.
- external arrivals to node i (if any) form a Poisson process,
- a customer completing service at queue i will either move to some new queue j with (fixed) probability or leave the system with probability, which is non-zero for some subset of the queues.

Famous quotes containing the words definition of a, definition of, definition and/or network:
“Definition of a classic: a book everyone is assumed to have read and often thinks they have.”
—Alan Bennett (b. 1934)
“Beauty, like all other qualities presented to human experience, is relative; and the definition of it becomes unmeaning and useless in proportion to its abstractness. To define beauty not in the most abstract, but in the most concrete terms possible, not to find a universal formula for it, but the formula which expresses most adequately this or that special manifestation of it, is the aim of the true student of aesthetics.”
—Walter Pater (1839–1894)
“According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animals—just as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.”
—Ana Castillo (b. 1953)
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
