FAQ_ A) What are the difference between different kinds of software loading method ?  B) How to choose them/what are their application scenario ? C) Is there have any diffence between below software loading task and Patch upgrade task ?

 

1. Simulation package upgrade task,

2. Package diffusion upgrade/downgrade task

3. Package upgrade/downgrade task

Dear, thanks for your feedback. I have send your question to huawei engineer. Wait for a moment

@Babala Ok. Thanks Babala .Eagerly Waiting for your feedback.

Thank you for your question, for the details about the concepts, you can see the following documentation:

If you have any other question, please feel free to feadback to us.

This is the update the patch of OLT through NMS, i think it is simple for every one to know about this. ONly operate on U2000

Software upgrade/downgrade task
Application scenario:
1.When a software error occurs on a running NE, or when software codes are expanded for new services, the NE software needs to be upgraded.
2.When there are errors in the upgraded software or the NE version is later than what the live network requires, the NE software needs to be downgraded.
3. The software upgrade/downgrade task is used to upgrade and downgrade the software of the Access NE and Router/Switch/Security NE.

Patch update task
Application scenario:
When you rectify the faults in the NE program and modify the program for new services, you need to update patches for the software. You can upgrade software by updating patches without affecting the running of an NE.

Simulation package upgrade task
A package is a collection of software to be loaded on NEs. The loading attributes of each software are defined by a package description file. The NE Software Management loads the software on relevant boards according to the loading attributes defined in the description file.
Application scenario:
1.When a software error occurs on a running NE, or when software codes are expanded for new services, the NE software needs to be upgraded.
2.The Transmission/PTN NE software needs to be upgraded.
3.Before you load software on NEs, all software is saved on the server that runs the NE Software Management. After you load the software to NEs, the simulation package is not saved on the NEs. Therefore, the simulation package upgrade task is applicable to the NEs that have only small memory size and no CF cards.

Package upgrade/downgrade task
Software package is a collection of software to be loaded on NEs, which is a file package encapsulated by certain definition. The NE Software Management first load the software package on the control board of an NE, and then the control board allocates each software to boards according to the encapsulation definition.
Application Scenario:
1.When a software error occurs on a running NE, or when software codes are expanded for new services, the software needs to be upgraded.
2.When there are errors in the upgraded software or the NE version is later than what the live network requires, the NE software needs to be downgraded.
3.Before you load software on each NE board, the software package is loaded on the control board. After the loading, the software package remains on the control board. Therefore, the package upgrade/downgrade task is applicable to the NEs that have CF cards and a large memory size, and support package upgrade.
4.Package upgrade/downgrade tasks can be used to upgrade or downgrade the Transmission/PTN NE software.

Package diffusion upgrade/downgrade task
The NE Software Management calculates the diffusion trails of the software package based on the routing relationships of NEs, and then sets the diffusion relationships on these NEs. The NE Software Management loads all the software of the package on the first node on trails at one time. According to the diffusion relationships specified by the NE Software Management, the first node on the diffusion trails transfers the software package to next nodes on the trails for upgrade or downgrade.
Application scenario:
1.When a software error occurs on a running NE, or when software codes are expanded for new services, the software needs to be upgraded.
2.When there are errors in the upgraded software or the NE version is later than what the live network requires, the NE software needs to be downgraded.
3. The Transmission/PTN NE software needs to be upgraded or downgraded.

Dear Hasan, Thanks for sharing .....It's useful

Good information .....

Its Useful ....
