Embodiment Construction
[0045] based on the following Figure 2 ~ Figure 4 , specifically explain the preferred embodiment of the present invention.
[0046] The present invention provides a method for ensuring the safety and success of line card software upgrades in a distributed OLT system, the method comprising the following steps:
[0047] Step 1. Add the upgrade image header to the upgrade image file;
[0048] The source of the software upgrade process is controlled first, that is, the upgrade image file is controlled. A specific header is added to the online card software upgrade image.
[0049] The upgrade image header is divided into four parts. The first part is the header identifier TAG_BEGIN. The second part contains the identifier of the upgrade object and the attributes of the upgrade image. The third part is the sequence generated after the content of the upgrade image is verified. The fourth part TAG_END for the end;
[0050] like figure 2As shown, in this embodiment, the set spe...
