Embodiment Construction

[0037] The implementation process of the breakpoint resume method in the embodiment of the present invention is as follows: figure 1 shown, including the following steps:

[0038] Step 101: the service provider adds a file summary field in the service list of the service server;

[0039] Here, the description of adding a file summary field in the service list of the service server is specifically:

[0040] Select one or more file verification algorithms; each service provider uses the selected file verification algorithm to obtain the file summary of each file provided by itself, and through the service server, in the service list corresponding to each file provided by itself Add the file summary of the file in the table item; among them,

[0041] The file check algorithm can be CRC32 check algorithm, secure hash algorithm 1 (SHA1), information-digest algorithm 5 (MD5), etc.; the files provided by each service provider include various files that the service provider can prov...

Abstract

The invention discloses a breakpoint continuous transmission method, which comprises the following steps of: when file downloading is interrupted, determining a breakpoint continuous transmission table entry through a table entry containing the file abstract of the downloading interruption file in a service list, and implementing breakpoint continuous transmission according to the breakpoint continuous transmission table entry. The invention also discloses a breakpoint continuous transmission system, which comprises a service provider, personal network equipment (PNE) and a service server. The method and the system can greatly reduce the time intervals between downloading interruption and breakpoint continuous transmission.

Description

technical field [0001] The invention relates to file downloading technology, in particular to a method and system for resuming transmission from breakpoints. Background technique [0002] The personal network service system includes a service server and each personal network (PN, Personal Network) managed by the service server; wherein, the PN is a personal network equipment (PNE) such as a portable digital product, a home smart appliance, a mobile terminal, etc. owned by an individual. A connected network, wherein the PNE equipment with the network access function is directly connected to the service server, which is called a PN gateway (PNGW, PNGateway), and the PNE without the network access function is connected to the service server through the PNGW; Each PNE in the PN completes the PN service by interacting with the service server, or interacting with other PNs or other networks through the service server. The service provider of the PN service may be the service serve...
