If has, only need to send one video current  to one of the VLANs, the video would be copied and transmitted  to all VLANs which have the same demand of this video. In this way, the bandwidth of total video current will be reduced greatly which can guarantee the liability of the network.


Support differentiate service of rate limitation

To meet the demands of different  customers, the service provider need to provide a network infrastructure which can guarantee the performance and flexibility, the uploading rate can assure the bandwidth rates of different businesses.

Uploading access control mechanism
