“…To solve the link conflict problem, the time domain approach is used. From previous researches we analyzed that Space domain approach [1], time domain approach [10], [12], [15] and wavelength domain approach [2], [6], [7] are the three approaches which can be used for to avoid conflicts. In Time Domain Approach, the connections are established at different time periods when two or more wavelengths try to access the same wavelength at same time [1], [10], [12], [15].…”

Multistage interconnection networks (MINs) are high performance indispensable networks with low cost for broadband switching technology and multiprocessor systems. Crosstalk is a critical issue in MINs. The undesired coupling of two or more wavelengths is reason behind Crosstalk and Link Conflicts and Switch Conflicts can cause it. In Electrical or traditional MINs, link conflict is the only reason behind crosstalk but in optical MINs, both conflicts (switch conflicts and link conflicts) occurs in crosstalk. In traditional MIN or electrical MIN, the link conflict problem can also be arises because of congestion. In this paper, we are going to discuss about link conflict problem in electrical MIN. In this paper, we proposed a new link conflict detection method named Link Window Method (LWM) to detect link conflicts in omega MIN. Congestion can also be identified in switches with the help of proposed algorithm.

“…Problem overview: Crosstalk in OMINs is an important problem. To avoid crosstalk problem which is caused by coupling two signals within a switching element (Almazyad, 2011), various approaches have been proposed by many researchers. In this research, we are interested in a network called optical omega network which has shuffle-exchange connection pattern.…”

Problem statement: A class of dynamic interconnection networks is Multistage Interconnection Networks (MINs) that connects input devices to output devices through a number of switch stages. MINs have assumed importance in recent years; because of their cost-effectiveness. Optical MINs are one type of MINs that have large transmission capacity in the communication networks. There is a major problem in Optical MIN that is crosstalk, which is caused by coupling two signals within a switching element. Approach: To avoid crosstalk in Optical MINs many algorithms have been proposed by many researchers that we review applying five routing algorithms and scheduling them in the Optical MINs. Results: The comparative results of routing algorithms show affective of avoiding crosstalk in number of passes and execution time for different algorithm. Conclusion: The challenge between these routing algorithms is thoroughly investigated, by applying them on Optical MIN and showing which algorithm has better performance to avoid crosstalk

In order to avoid crosstalk, a new architecture is proposed for Optical Multistage Interconnection Networks (OMINs). In the new architecture, two switches are replaced by one switch in each row. Reduction in the number of switches makes the considerable reduction in the execution time. To study the performance of the new architecture, analytical techniques also can be used effectively. The theory of probability is used to derive mathematical equation for network bandwidth allocation of a unit load. The obtained results show the improvement in the network performance. By increasing load, the bandwidth is reduced. In addition the simulation is applied to validate the new architecture and show improvement in the performance by approximately 30 % reduction in the execution time.
