Abstract : Resource provisioning is usually done for static and dynamic traffic. It is considered to be a major problem in communication networks. Many proposals have been developed to overcome the issues, but as the demands are increasing day by day the researchers are mainly focussed towards developing efficient strategies. In multi-domain optical networks, the scheduled traffic (ST) like the looming interactive media and multi-vendor applications is repeated and recurring day by day. The traffic is usually more during working/functional hours and slump during non-working hours. Hence, the deficiency of resources is increasing which leads to the blocking of demands. To overcome this, Earliest set-up demand first (ESDF) and Earliest tear-down demand first (ETDF) schemes have been developed but these have few limitations. In ESDF, the consumption of resources will be more and in ETDF, the delay will be more. To resolve the problems of existing schemes we propose an efficient routing protocol Earliest Execution Demand First (EEDF) which gives priority to the execution time of the demands. In the simulation results we notice that the proposed protocol outperforms the existing strategies with respect to number of connections accepted and resource utilization ratio (RUR). © 2017 IEEE.
