Embodiment Construction

[0025] The present invention will be further explained below with reference to the drawings and examples.

[0026] figure 1 Shown is a schematic diagram of the overall structure and core ideas of the method of the present invention. The entire network system is divided into a data collection layer, a network routing layer, a data center layer, and an application layer. There are three types of transmission streams and two routes in the network, which are data streams. Service flow, service request flow and upstream routing and downstream routing. In this example, the entire network has only one data center, and content router nodes are evenly distributed in the network. The normalized network model is defined as follows: the network can be described as an undirected graph G = (R, E), where R is a non-empty set of vertices, composed of content router nodes; E is a set of unordered two-tuples composed of elements in R , Is the communication link between any two nodes. The set of ...

Abstract

The invention discloses a service aggregation and caching method for a service network. In the process of uploading mass data to a data center through a content routing node, a data packet is converted into a service packet when passing through an edge node, then the service packet is transmitted upwards hop by hop, and meanwhile, an aggregation node periodically performs service aggregation on the received service packet. After a plurality of service packets are aggregated to form a larger new service packet, the aggregation node correspondingly caches the service packet locally and directlyreturns data when the service packet is requested by a user later. According to the method provided by the invention, each content routing node can be used as a small data center to carry out data processing and request response, so that the load of a data center server is reduced by multiple times. Theoretical analysis and experimental results show that compared with a traditional data center network and a service aggregation method adopted as well, the method can reduce the transmission data volume to a greater extent and remarkably improve the network performance.

Description

Technical field [0001] The present invention relates to the field of network communication, in particular to a service aggregation and caching method of a service network based on big data and a cloud platform. Background technique [0002] The upsurge of cloud computing and big data has led to the rapid development of the Internet of Things technology, making the amount of devices and data connected to the network increase exponentially. Since 2011, devices connected to the Internet of Things (such as smart phones, cities, industrial sensing devices, etc.) have exceeded the number of people, reaching 9 billion (units) of devices. A report from Cisco shows that the data traffic generated by the Internet of Things has accounted for 69% of the entire Internet traffic in 2014, which is 30 times the data traffic in 2000, and the data volume growth is still accelerating. [0003] This unprecedented increase in the amount of equipment and data has brought unprecedented challenges to the...
