Problems solved by technology

[0005] However, when the transmitted data packets are large, the way of merging data packets only saves the packet header, and the bandwidth saved is very small, which fundamentally fails to meet the requirements of acceleration.
All of today's data compression algorithms generally have h

Abstract

The invention discloses a secure transmission optimization method and device for a narrow-band network and relates to the network communication technology. By the adoption of the optimization method and device, the speed of the narrow-band network can be increased. The secure transmission optimization method for the narrow-band network is characterized by comprising the steps that data to be sent are lengthened and divided into blocks through a sending end, a data recovery script is generated, the repeated data blocks are deleted, and the data blocks left after the repeated data blocks are deleted are stored in a local lengthened data block library; the sending end sends the data recovery script to a receiving end, and the receiving end analyzes the script and determines whether a local data block library at the receiving end is lacking in data blocks used for recovering the sent data; the receiving end sends the information of the absent data blocks back to the sending end; the sending end sends the corresponding data blocks to the receiving end according to the information fed back by the receiving end; the received data blocks are stored in the local lengthened data block library at the receiving end after being received by the receiving end; local generation of data is completed by the receiving end through the data recovery script and the local lengthened data block library, and then all the data needing to be sent by the sending end are obtained.

Description

technical field [0001] The invention relates to network communication technology, in particular to a narrowband network security transmission optimization method. Background technique [0002] Communication in a narrowband network environment requires that the amount of transmitted data be as small as possible, otherwise it will easily cause network congestion and seriously affect the network speed. In the prior art, two methods are mainly adopted for transmission acceleration in a narrowband network environment: one is to combine data packets; the other is to decompress data. [0003] The method of merging data packets refers to intercepting all small data packets to be sent on the network according to a certain strategy, and then combining multiple packets into one large packet, thereby reducing the overhead of small packet protocol headers and speeding up transmission. This technology has a certain effect on the transmission of a large number of small data blocks, such a...
