Embodiment 1

[0080] Such as figure 1 As shown, the present invention adopts an edge cache system based on edge-cloud collaboration and edge-edge collaboration modes. In the edge cache system, a collaborative cache strategy for Internet service applications in edge nodes is studied. It is assumed that the cloud data center owns / configures all Internet service applications. Due to the limited storage capacity of edge nodes, only source files (or application installation packages) can be downloaded / obtained from the cloud data center and then installed and configured in the nodes. Usually, due to the limited capacity of the edge node, after installing a new service application, the edge node will discard the source file (or application installation package).

[0081] Such as figure 2 As shown in , an edge collaborative caching method for load balancing of differentiated services in Internet scenarios includes the following steps:

[0082] S1: Define the response actions and cache parameter...

Abstract

The invention discloses a load balancing edge cooperative caching method for an Internet scene differentiated service. The method comprises the following steps: S1, defining response actions and caching parameters made by edge nodes in an edge cooperative caching system after a user sends an application service request; and S2, initializing parameters, executing an edge cooperative caching process, and calling a load balancing strategy and a differentiated service strategy. The differentiated service strategy is adopted in the edge cooperative caching system to meet the requirements of different service levels of different users in an Internet scene, queuing delay of user requests is reduced through the load balancing strategy, stability of node response request delay is improved, and userexperience is improved.

Description

technical field [0001] The present invention relates to the technical field of edge collaborative caching, and more specifically, to an edge collaborative caching method for load balancing of differentiated services in Internet scenarios. Background technique [0002] In the era of big data, with the explosive growth of Internet data, IDC predicts that more than 50 billion devices will be connected to the Internet by 2020, and Internet data will reach 44ZB, 70% of which will need to be processed in edge devices. In addition, a large number of Internet users frequently request / acquire content from the cloud, which puts a huge load pressure on the server of the network service provider SP. In the peak period of network data transmission in the background of big data, traditional cloud computing technology is difficult to meet the QoS and QoE due to the huge load pressure on the cloud server. [0003] A large number of studies have shown that edge caching sinks files or servic...
