Lightest carrying optical track resource allocation system for optical track network

Abstract

The invention discloses a lightest carrying optical track resource allocation system for an optical track network. The system comprises a tag value computing module, a first allocation factor computing module and an optical track resource allocation control module, wherein the tag value computing module is used for computing a tag value bidi of a data request node; the first allocation factor computing module is used for computing and judging whether the priority level of a new request is higher than a first allocation factor Wj occupying the priority level of of a node of an optical track; and the optical track resource allocation control module is used for allocating the optical track to the new request according to the tag value bidi and the first allocation factor Wj. If the optical track j ensures that the Wj is more than 0 and the quantity of the optical track meeting the condition is 1, the optical track is allocated to the new request; and if the quantity of the optical tracks meeting the condition is larger than 1 and the optical tracks with bidH and j being equal to 0 exist, the optical track with the largest Wj is selected and is allocated to the new request. The system can effectively realize the optical track resource allocation in the optical track network, meet the requirement on real time of optical track network service and improve the utilization factor of optical track resources.
