Multistage Interconnection Networks (MINs) are often employed for implementing NGNs, but while MINs are fairly flexible in handling varieties of traffic loads, they tend to quickly saturate under broadcast and multicast traffic, especially at increasing size networks. As a response to this issue, multilayer MINs have been proposed, however their performance prediction and evaluation has not been studied sufficiently insofar. In this paper, we evaluate and discuss the performance of multilayer MINs under multicast traffic, considering also two levels of packet priorities, since support for multiple QoS levels is an indispensible requirement for NGNs. Different offered loads and buffer size configurations are examined in this context, and performance results are given for the two most important network performance factors, namely packet throughput and delay. We also introduce and calculate a universal performance fac&shy;tor, which includes the importance aspect of each of the above main performance factors. The findings of this study can be used by NGN system designers in order to predict the performance of each configuration and adjust the design of their communication infrastructure to the traffic requirements at hand.</span></span></span></p

Formulating broadcast reliability equations on multilayer multistage interconnection networks

“…In the field of MLMINs, the performance parameters such as throughput, delay, blocking probability, to name a few, have been adequately analyzed in previous works [15,16,[18][19][20][45][46][47][48][49]. All of the previous analyses reflect the fact that multilayer MINs have a great potential in terms of key performance parameters, especially the throughput and delay.…”

“…In addition, the required multicast traffic distribution, in certain areas, is used very often in modern grid systems. These events create the need for interconnection network technology, which is used to improve the performance of new fabrics that are under development [18,19].…”

On Performance Evaluation of Advance Irregular Alpha Multi-Stage Interconnection Network-2

“…Multi-stage interconnection (MIN) provides the reliable and fast communication to the parallel processing applications. Faults in MIN prevent the data transmission process [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Therefore, designing a good fault tolerant MIN is the key concern.…”
