Software upgrades are important in the communications products

which are also frequently used in engineering and network test scenarios.Using the single manual upgrade way

there are several problems as long overall upgrade time and low upgrade reliability.In order to reduce the impact of protocol stack software upgrades on business interruption

improve product reliability

and enable easy product maintenance

we require system package based upgrade function.Based on the distributed digital equipment upgrade program

all the single disks are started from the master download package

and all software are centralized stored and managed in the form of equipment package by the main control.The single disk no longer saves the single disk package.However

due to requirements of development and test

it need to retain the local start function.In the real business upgrade period

since the associated software package has been registered and verified

the time-consuming is short during the activation and upgrade period

which can minimize the impact on the business

reduce the risk of upgrade failures and operational cost.
