Abstract

The invention relates to a traffic grooming cloud edge computing network computing resource balanced scheduling method and system. The method comprises the steps: acquiring network topology information, initializing network parameters, and generating a group of connection request sets; for each connection request, judging whether the source region and the destination region have enough computing nodes for computing resources to process the connection request or not; performing calculating by using a K shortest path algorithm to obtain K candidate paths from a source node to a destination node, arranging the paths according to priorities, and sorting the transmission broadband of the connection request; sequentially judging whether idle spectrum resources on candidate transmission paths selected according to the priorities meet spectrum resource requirements of the connection request and spectrum consistency and spectrum continuity conditions of spectrum flexible optical network transmission; and updating link spectrum resource state information and node computing resource information in the central controller, and computing the connection request blocking rate in the whole network. The method is beneficial to reducing the blocking rate of services and improving the utilization rate of network spectrum resources.

Description

technical field [0001] The present invention relates to the technical field of cloud-edge computing, in particular to a cloud-edge computing network computing resource balance scheduling method for flow grooming. Background technique [0002] In recent years, with the rapid development of the Internet of Things (IoT) and the widespread use of big data applications, users' demand for network computing resources has increased dramatically. In addition, technological advances in smartphones, laptops and tablets have enabled the emergence of new demanding services and applications. Although new mobile devices are becoming more and more powerful in terms of central processing units (CPUs), they may not be able to process heavy-duty applications in a short period of time. Cloud computing has powerful computing capabilities. Devices can offload computing resources and transmit computing tasks to remote cloud servers for execution, which can effectively alleviate the problem of lar...
