Introduction The multistage interconnection Network is an essential network for the Parallel computing applications .It contains N inputs to N outputs and is known as an N×N MIN. The parameter N is called the size of the network. In this paper we study the performance of optical multistage Interconnection network. Omega network is a network configuration after used in parallel computing architecture .It is an indirect topology that relies on the Perfect Shuffle interconnection algorithm. The omega network is a highly blocking through one path can always be made from input to any output in free network. It connects N inputs to N outputs and is known as an N*N MIN. Here N is the size of the network. In Omega network contains N/2 switches. An omega network is a log2N stage shuffle –exchange Interconnection network .Here multistage Omega network N=8 Multistage Interconnections network establishes a reliable communication between source and destination. But now a days electro optic technologies have built optical communication a reliable and fast network that fulfill the Increasing demands of users. II. Analysis for the Network Most of the interconnection network analysis related to identical processor And a uniform reference model. We shall analyze the performance of the n- stage Banyan network discussed. 1. Fixed size packets are generated by the modules at each source address 2. Arrival of packets at the network inputs are independent and identical. 3. A connection between two switches can carry the packet in each cycle. 4. If two packets arriving at two distinct network inputs require the use of common link between two stages, one of the packets is discarded. 5. The switches and links have no internal buffers to temporarily store an incoming packet that cannot be forwarded in the current. 6. There is no blocking at the output links of the network. This means that the output links have at least the same speed as the internal links. Moreover, if the network is uniform, then for each stage in the network, the patterns of packet arrivals at the inputs of that stage have the same distribution. While Banyan networks are very attractive in their simplicity, other considerations such as performance or reliability sometimes dictate the use of more complicated ABSTRACT: Multistage interconnection networks (MIN) are among the most efficient switching architectures for the number of switching Element (SE). Optical crosstalk in optical multistage interconnection network on the omega network topology Switches are arranged in multiple stages. These switches also referred to as switching element (SEs) have two input and two output ports, interconnected to the neighboring stages in a shuffle exchange connected pattern message routing in such a network is determined by the interstate connection pattern. Optical Multistage interconnection networks (OMIN) are advanced version of MINs. The main Problem with OMIN is crosstalk. The main purpose of this paper is to Present crosstalk free modified omega network, which is based on time domain approach. This paper presents the source and destination based Algorithm (SDBA) .SDBA does the scheduling for source and their respective destination addresses for the message routing. SDBA is compared with the crosstalk modified omega network (CFMON).CFMON also Minimizes the crosstalk. This paper is the modified form of the omega network.
