Broadcast and storage network-based fog computing architecture content cooperative distribution method and application system

Abstract

The present invention discloses a broadcast and storage network-based fog computing architecture content cooperative distribution method and application system. According to the broadcast and storagenetwork-based fog computing architecture content cooperative distribution method and application system of the invention, a broadcast and storage network is utilized to enhance the content active pushcapability of a traditional fog computing architecture and reduce the consumption of internet bandwidth by the traditional fog computing architecture; on the basis of the centralized control idea ofthe software-defined network (SDN), a multi-granularity cooperative storage mechanism which considers both broadcast content and Web cache content is put forward; on the basis of the multi-granularitycooperative storage mechanism, all nodes in a domain are centrally maintained and controlled through a controller, and an efficient content forwarding strategy is formulated for a fog server in the domain; and the content cooperative distribution of the nodes in the domain is realized through the controller. With the broadcast and storage network-based fog computing architecture content cooperative distribution method and application system of the invention adopted, the content active push capability of the fog computing architecture can be effectively enhanced, user request delay can be reduced, and user experience can be improved.

Description

technical field [0001] The invention relates to a content collaborative distribution method and an application system of a fog computing framework based on a broadcast storage network, which can reduce the response delay of end user requests and improve user experience, and belongs to the technical field of the Internet. Background technique [0002] Cloud computing can overcome the common disadvantages of resource monopoly, low data center business density and low system resource utilization in traditional application systems, but it still has defects such as inability to effectively support delay-sensitive applications and consume a large amount of network bandwidth. For this reason, Cisco (Cisco) proposed the concept of fog computing (Fog Computing), which extends the network computing characterized by cloud computing from the network center to the edge of the network, and uses fog computing to describe the intermediate state between cloud computing and terminal computing....

AI Technical Summary

Problems solved by technology

Considering that the current fog computing architecture has shortcomings such as weak active push capability and content distribution consumes Internet bandwidth, it is difficult to overcome these shortcomings with traditional technologies, and the advantages of the broadcast storage network can effectively overcome these shortcomings

However, on the one hand, there is currently no fog computing architecture implementation scheme based on the broadcast storage network in the industry; on the other hand, there are still many difficulties in building a fog computing architecture based on the broadcast storage network, such as the storage collaboration between Efficient management and control of servers, collaborative content distribution method for multiple nodes linkage, etc.
