Abstract
Systems, methods, and instrumentalities are disclosed for managing real-time traffic video flows. A node may comprise a processor configured to receive a first real-time video traffic flow. A state variable may be associated with the first real-time video traffic flow at the node and a state variable may be associated with the second real-time video traffic flow at the node. The first real-time video traffic flow may comprises plurality of packets and each packet may comprise a lost packet indicator. The node may be configured to drop a first packet in the first real-time video traffic flow, update the state variable associated with the first real-time video traffic flow at the node to indicate the dropped packet, and update the lost packet indicator for a second packet in the first real-time video traffic flow based on the dropped packet.
