Problems solved by technology

The disadvantage of this method is that it does not realize the effective utilization of multi-dimensional resources by quantifying the degree of fragmentation of multi-dimensional resources, resulting in resource fragmentation and affecting the work efficiency of the data center; this method belongs to a fixed heuristic strategy and lacks network The interaction of the real-time state of the environment cannot adaptively optimize the scheduling strategy in the case of dynamic changes in the network environment and task requirements, and is limited to a certain extent in terms of resource optimization and network performance improvement

The disadvantage of this method is that it only considers the task scheduling situation when user tasks request one-dimensional resources. For multi-dimensional resource task requests, this method does not clearly indicate how to schedule. However, in the actual cross-data center network task scheduling , the resource requests of user tasks are usually composed of multiple resources, so this method cannot be applied to cross-data center network task scheduling
