To derive the exact reliability expressions for large Multistage Interconnection Networks (MINs) can become rather complex. As network size increases, the reliability bounds could be used to estimate the reliability of the networks. In this paper, terminal, broadcast, lower and upper bounds network reliability will be determined. Lower bound reliability is the minimum probability that the system will be operational for a specified time. Upper bound reliability presents an optimistic view of probability that the system will work at some specified time, which is not the center of attention in terms of reliability point of view. If the lower bound reliability provides sufficient assurance that the system will be operational at some specified time, then no further effort for obtaining the exact reliability expression is necessary. As examples, the derivation of terminal, broadcast, lower and upper bounds network reliability expressions of the extra-stage cube network will be demonstrated.

Recent improvements in the optical interconnection technology allow creation of interconnection networks that are larger, faster, and more power efficient than ever before. In this paper, characteristics and limitations of optical multistage interconnection networks (MIN) will be discussed. Then, an implementation of optical MIN for shuffle-exchange network will be presented, including its parameters such as connectivity, network complexity, signal path length, and total number of waveguide crossings. Shuffle-exchange network has been widely considered as a practical interconnection system due to the size of its switching elements and uncomplicated configuration. The reliability evaluation of shuffle-exchange network is demonstrated through a numerical example.
