Embodiment Construction
[0018] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings of the specification.
[0019] The following takes data download as an example for illustration. Data upload can be analogous to using this method or device.
[0020] The present invention discloses a method for resuming transmission of network data packets at a breakpoint, which specifically includes the following steps: Step 1. The network server stores the network data packets in sequence according to the time of capture, and each network data packet has a corresponding Timestamp: All network data packets are stored on the server in a certain order, and they all have a timestamp identifier. Even the network data packets under the same timestamp, their storage has its own unique order.
[0021] Therefore, as long as the timestamp is found, the corresponding network data packet can be found. Step 2: The download request initiator initiates a down...

The invention relates to the technical field of network data package download, and discloses a method for breakpoint transmission of network data packages. The method specifically comprises the steps: firstly, a network server stores network data packages according to the time order of package capture; secondly, the network server reads data packages of a corresponding timestamp according to a download time segment; and thirdly, after a download request initiator receives the network data packages, the download request initiator saves the timestamp and the last 46 bytes of the last network data package of each time of transmission, and after reconnection, sends the recorded timestamp and last 46 bytes of the last network data package to the network server, and the network server successively reads data packages under the timestamp until the last N bytes of a certain data package are consistent with N bytes of the last transmitted data package, and uses the next data package as the first re-sending data package. The method is capable of avoiding transmitting the same data packages repeatedly.
Description
Technical field [0001] The present invention relates to a transmission technology for downloading or uploading data packets, in particular to a method and device for resuming transmission of network data packets at a breakpoint. The method and device can avoid repeated downloading or uploading of data packets. Background technique [0002] At present, there are a large number of users who need to download data packages with a large time span (more than 24 hours), so the download time is relatively long. During the downloading time, there is often a disconnection due to the user's network environment, and it is necessary to reconnect to download. The more conventional approach is to start downloading again when the endpoint is dropped, such as figure 1 As shown in the schematic diagram of the processing method when a breakpoint occurs during the download of the data packet, when the download of the data packet reaches 3 seconds and 500000 nanoseconds, the console and the server ar...
