Priority based traffic balancing routing protocol for WDM optical networks

Requirement for high bandwidth traffic has been increasing very rapidly. Efficient and effective provisioning of resources is very important now-a-days. Due to the increase in number of users, providing sufficient bandwidth has become a difficult task for the service providers and network operators. Researchers have developed many techniques to resolve this issue but they have not reached to full extent. The internet traffic is heavy during the working or office hours and less during nonworking hours. To overcome the above issues, different policies like Policy1 - Traffic Balancing (P1-TB), Policy2 - Traffic Balancing (P2-TB) and Policy3 - Traffic Balancing (P2-TB) have been developed but these schemes have few limitations. To resolve the complications of above, we have proposed an algorithm which considers the data rate, level of employee in an organization. The demand with high data rate (almost equal to the capacity of the wavelength of the fiber) will be processed directly and the demand with the lower data rate will be groomed with the existing low data rate demands. This leads in serving more number of demands. From the results, we monitored that the new protocol outperforms the existing schemes with less blocking probability by serving more number of requests.
