| Popis: | Requirement for high bandwidth internet traffic is growing rapidly now-a-days. Utilization of the available resources becomes troublesome due to rise in the number of users. So it is important to provide the resources efficiently. To solve the problem of resource provisioning, many developments have been made by the researchers. During working hours, the scheduled traffic is huge and sluggish during rest of the time which leads to the blocking of requests during working hours. To overcome the above issues, different schemes like Earliest set-up demand first (ESDF) and Earliest tear-down demand first (ETDF) have been developed. These schemes have few limitations like consumption of resources in ESDF and more delay in ETDF process. To resolve the complications of the existing policies, we proposed Power Efficient-Resource Utilization protocol (PERUP) wherein the capacity of the wavelength and the data rate of each demand will be considered. 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 Resource utilization ratio (RUR), number of requests served and proper usage of bandwidth. Here we also focus on the power consumption of the network by selecting the route based on the cost of the link. |
