Background

The QCloud provides customers various cloud services including audio and video cloud service. Customers use it to store, upload and download audio/video data.

However, as a result of the big amount of audio/video data, there are frequent lost frames or data loss causing inconvenience for users.

The engineers need to locate and solve those bugs and problems by reading and understanding complex upload and download data.

Process
