Communication method and system based on coding cache, and storage medium

Abstract

The invention discloses a communication method and a system based on coding cache and a storage medium. The method comprises the steps of acquiring resident user information in an area; recording a request file of the resident user, and constructing a common file database; when determining that the current time period is the network low-peak time period, updating the resident user information andthe common file database by adopting a file size-based coding cache scheme, and sending a file to the user according to the file size and the file popularity; and when the current time period is determined to be the network peak time period, identifying the size of the request file and determining the group to which the user belongs according to the received user request information, and then sending the same data packet file to the users in the same group by adopting a multicast transmission technology. According to the communication method, the network congestion during peak hours can be relieved, the network pressure is reduced through the multicast transmission technology, the efficiency and the practicability are improved, and the method can be widely applied to the technical field ofcommunication.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, system and storage medium based on coding cache. Background technique [0002] With the popularization of 4G technology and the advent of the 5G era, users' demand for wireless network communication is increasing, and network traffic in densely populated areas is growing exponentially. Operators are facing the dual challenges of limited spectrum resources and rising electricity costs. Under this premise, how to reduce network throughput and reduce network load has become a topic of concern to people. The network traffic has the characteristics of large changes in different time periods of the day. Therefore, a method to alleviate network congestion during peak hours is to make full use of the memory distributed on the network (end users, servers, routers, etc.) The content is pre-cached during peak hours; and during peak hours, the server (b...

Problems solved by technology

The traditional centralized encoding and caching scheme is realized under the assumption that the file size is the same. However, in reality, the size of the file requested by the user may be quite different, so this scheme cannot be directly applied; at the same time, the retrieval of the existing technology found that currently based on Research on caching and transmission schemes for different file sizes is still scarce

In summary, the most traditional non-coding cache and unicast communication will inevitably bring huge network pressure and low efficiency under the situation of network traffic surge; while the classic centralized coding cache theory and communication methods are too idealistic, Can't solve real problems well
