The simulation approximately to 7. The proposed HON hybrid optical network architecture employs a different set of four transmitter, Fig.
DWDM technology technique is used in proposed Fig. It shows an error of approximately 1.
The optical transmitter is used to convert the electrical signal into optical form, and launch the ensuing optical signal into the optical fiber.
The transmitter consists of the following components: an optical source, electrical pulse generator and an optical modulator. The key element of an optical receiver which converts light into electricity using the photoelectric effect is a photodetector, An OADM consists of three stages: an optical de- multiplexer, an optical multiplexer and between them a way of reconfiguring the paths between the multiplexer, de-multiplexer and a pair of ports for adding and dropping signals.
The de-multiplexer splits wavelengths in an input fiber onto ports.
The reconfiguration can be accomplished by optical Fig. Communications Magazine, November Sone, A. Watanabe, W. Imajuku, Y.

In this paper, we are considering all-optical networks, since they present a lower cost and the constraints imposed by the physical layer are more severe. It occurs due to the noise accumulation and distortion along the transparent lightpath  . There are two main challenges in all-optical networks: i to design an efficient routing and wavelength assignment RWA algorithm, which has a direct influence in the network performance, and ii to obtain an acceptable optical signal-to-noise ratio OSNR at the destination node for each lightpath .
These requirements are necessary for providing quality of service QoS .
The RWA problem consists in to find a route and to assign a wavelength for each connection request. The RWA process can be classified in two types: static or dynamic .
In the static case, the call requests are known in advance and the RWA operations can be performed in an off-line manner.
The main objective is to minimize the number of wavelengths needed to establish the call requests for a given physical topology. In the dynamic case, the target is to minimize the blocking probability, while optimizing the availability of resources. In general, the solution for the dynamic RWA problem is simplified by decoupling the problem into two separate sub-problems: the routing R and the wavelength assignment WA .
The performance of a dynamic RWA algorithm can be assessed in terms of the blocking probability BP , which assesses the chance of failure in the implementation of a given network request. It can occur due to the lack of resources or inadequate quality of transmission QoT of the lightpath .
Several solutions can be found in the literature for solving the routing problem in optical networks. In general, they are classified in three types: fixed routing, fixed-alternative routing and adaptive routing.

The fixed routing algorithms always choose the same route for a given source-destination pair. The fixed-alternative routing algorithm chooses a route from an ordered list of fixed routes depending on a predefined policy.
The adaptive routing algorithms consider the current network state to determine the routes . In the SP algorithm, the route is defined based on the minimum total physical link length.

The MH algorithm finds the physical route with the minor number of optical links. The LRW algorithm finds the routes based on the wavelength availability aiming to distribute the load over the entire network. One must observe that the LRW algorithm uses the current information of the network i.
In this paper, we are considering the MU algorithm. The MU algorithm selects the most used wavelength in the entire network and it keeps the spare capacity of less-used wavelengths.

The de-multiplexer splits wavelengths in an input fiber onto ports. The third step is to use a global optimizer in order to find the coefficients for the power series. In general, the solution for the dynamic RWA problem is simplified by decoupling the problem into two separate sub-problems: the routing R and the wavelength assignment WA .
