Edge computing transfers computing tasks from centralized management to the edge of the network, providing services nearby, reducing the amount of data transmission and ensuring data security. In order to study and apply edge computing system, this paper mainly discusses the background and current situation of edge computing. It introduces several typical edge computing systems, and compares them in the aspects of system characteristics, application fields and limitations, so as to help users understand edge computing system.
This paper proposes two solutions about bandwidth reservation. On the one hand, the algorithm strategy of network resource bandwidth reservation is considered, and on the other hand, the scheduling method of bandwidth reservation for multi-user and multi-task is considered. In the process of bandwidth transmission, attention to a single request task can be placed on the user as a whole, so that the user's bandwidth scheduling can be optimized. In addition, the network bandwidth scheduling table on the transmission path is divided into a batch of bandwidth allocatable areas, which can be used to schedule task requests iteratively when processing bandwidth scheduling request tasks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
