چکیده
In this paper, we analyze the wavelength assignment problem in optical WDM mesh network. Firstly the performance of Random algorithm, First-fit algorithm and Wavelength conversion is analyzed. Then new algorithm is developed from existing conversion algorithm. Proposed algorithm reserve the resources for the primary light paths and secondary light paths. Then extensive simulations are done on different networks to evaluate the performance in terms of blocking probability. Then comparison is performed for the blocking probability of various algorithms with number of links and channels are kept constant and the variation in number of load per link (in Erlangs). The results show that the proposed algorithm routing performs better than first two strategies. The performance of the modified wavelength conversion

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...

We propose a novel WDM aware weight function for solving the Routing and Wavelength Assignment (RWA) problem in optical WDM networks taking into consideration factors like number of used wavelengths , availability of free wavelengths and route length jointly under dynamic traffic conditions. The performance of proposed routing strategy is studied in combination with first-fit, and most used wav...

Aggregation of wavelengths into wavebands is an attractive, cost-efficient way to facilitate switching and routing in optical networks. In this paper, we study the waveband routing and wavelength assignment (WRWA) tasks in hierarchical WDM mesh networks with optical crossconnects that can route multiple granularity (wavelengths and wavebands) at the same time. We solve the waveband routing and ...

متن کاملDynamic Traffic Grooming using Fixed-Alternate Routing in WDM Mesh Optical Networks
There is a mismatch between lightpath channel capacity and traffic request capacity in wavelength division multiplexed (WDM) optical mesh networks. Traffic grooming is needed to resolve this mismatch in an efficient way. We study the dynamic traffic grooming problem in WDM mesh networks using the fixed-alternate routing (FAR) approach. Based on the FAR approach, we propose the fixed-order groom...
