Description

technical field

[0001] The present invention relates to the field of mobile edge technology, in particular to a device and method for collaborative distribution of mobile streaming media edge based on differential privacy. Background technique

[0002] With the explosive growth of the number of mobile devices and the rapid development of wireless communication technology, the global data traffic of mobile networks is increasing exponentially. According to the Cisco Visual Networking Index forecast, global Internet traffic will increase nearly three-fold from 2017 to 2022. In 2017, mobile streaming media traffic accounted for 60% of global Internet traffic, and this proportion is expected to rise to 78% by 2022. The key to the success of mobile streaming media services is to provide users with high-bit rate, low-latency, and distortion-free streaming media content. The explosive growth of streaming media data traffic makes it difficult for the traditional streaming media cont...
