Bandwidth management device, central management device and method of bandwidth management
First Claim
1. A bandwidth management device for streaming media, the bandwidth management device comprising:
- a first receiver, configured to receive attribute information of media devices;
wherein a criticality factor for indicating an importance level of each of the media devices and an activity factor for indicating an active level of each of the media devices are included in each piece of the attribute information, the activity level reflecting how often the media device generates and sends the media streaming during a time period;
a second receiver, configured to receive media streaming from the media devices; and
a bandwidth assigner, configured to assign an adaptive bandwidth for each piece of the media streaming at least based on the criticality factor and the activity factor each piece of the media streaming and an available bandwidth value.
