Title:
REALLOCATION METHOD AND SYSTEM BASED ON MAXIMUM TOLERABLE DELAY IN EDGE-CLOUD-COMPUTING-BASED ELASTIC OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2024/092994
Kind Code:
A1
Abstract:
The present invention relates to the technical field of elastic optical networks. Disclosed are a reallocation method and system based on a maximum tolerable delay in an edge-cloud-computing-based elastic optical network. The method comprises: constructing and initializing an edge-cloud-computing-based elastic optical network model, and generating a connection request and classifying the connection request by the degree of emergency according to a maximum tolerable delay time; establishing a candidate transmission path set of the connection request, calculating the number of spectrum slots required for the connection request on each candidate path, and prioritizing candidate paths; allocating network resources in conjunction with edge cloud computing, according to a priority order and the type of the connection request, searching for the number of idle required spectrum slots on the candidate paths, and after the search succeeds, establishing the connection request. The system comprises a network initialization module, a connection request generation module, a spectrum resource computing module and a spectrum resource allocation module. When a huge connection request arrives at a network, the present invention can effectively improve the resource utilization rate of the network, and reduce the blocking rate of the network.
