Problems solved by technology

However, when the user remotely downloads the file through the router, limited by the network conditions, there may be a problem that the download is too slow
Therefore, the existing method not only increases the storage and bandwidth burden of the server, but also increases the cost

Abstract

The invention provides a method for encrypting, storing, backuping and downloading file segments in a router with a storage function. The method comprises the following steps: receiving a file uploaded by a user and sending report information to a server by a current router; querying whether routers in available states exist at the periphery of the current router or not by the server; when the routers are in the available states, sending information of the peripheral routers to the current router by the server; encrypting received file segments uploaded by the user by the current router to obtain a plurality of sub-files, and transmitting the sub-files to the peripheral routers respectively for backuping; recording distribution information of the sub-files in the peripheral routers by the current router. According to the method, the bandwidth utilization efficiency of the user is improved and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for encrypting, storing, backing up and downloading files in fragments in a router with a storage function. Background technique [0002] A router, also known as a gateway device, is used to connect multiple logically separated networks. The so-called logical network represents a separate network or a subnet. When data is transferred from one subnet to another, it can be done through the router's routing function. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish flexible connections in a multi-network interconnection environment, and can connect various subnets with completely different data packets and media access methods. A router only accepts information from the source station or other routers, and is an interconnected device at the network layer. [0003] There may be various types of memory...
