Upgrade control method and control device

Abstract

The invention discloses a method of upgrading control, which includes: a device for upgrading receiving upgrading date by the network and the indicating information for indicating current received information is preserved by the device for upgrading when the network transmission is interrupted, the device to upgrade timing sending the information of transmission request to the remote end and the remote end sending response information to the device for upgrading after receiving the information of transmission request, the device for upgrading sending the indicating information to the remote end after receiving the response information sent by the remote end, after receiving the indicating information, the remote end sending the rest upgrading date which is not transmitted to the device for upgrading according to the indicating information. The invention also discloses a device of upgrading control. The invention can recovery the transmission of upgrading date for the device to upgrade when the network transmission of upgrading date is interrupted, avoid the failure upgrade and the palsy of the upgrading device in effect, and largely reduce the occupancy of the time and the resource.

Description

technical field [0001] The invention relates to upgrade technology, in particular to an upgrade control method and a control device, which belong to the field of communication technology. Background technique [0002] In the prior art, when upgrading a device to be upgraded through a network, if the network connection is interrupted and the transmission of the upgrade data is not completed, the upgrade data needs to be retransmitted, resulting in waste of time and resources. [0003] For example, when using the file transfer protocol (ftp for short) to upgrade the network of the device to be upgraded, if a network problem occurs that prevents the upgrade data from being transmitted, the transmitted upgrade data will be incomplete. When the network is restored, the file transfer needs to be performed again. Especially when the amount of upgrade data to be transmitted is relatively large, and the transmission of the upgrade data is almost finished before a network problem occ...

AI Technical Summary

Problems solved by technology

Especially when the amount of upgrade data to be transmitted is relatively large and the transmission of the upgrade data is nearing completion before network problems occur, retransmitting the upgrade data is a waste of time and resources

[0004] On the other hand, in the prior art, when the system file of the device to be upgraded is upgraded online, if the network connection is interrupted and the upgrade cannot be resumed in time, the upgrade may fail and the device to be upgraded may be paralyzed.
