Abstract:
1. A method for communicating data comprising: receiving, at a network device, a data packet included in a first data traffic flow; determining, by the network device, if a first rate of traffic of the first data traffic flow is less than or equal to a first threshold; in the event the first rate of traffic is less than or equal to the first threshold, marking, by the network device, the data packet with a first marker type; in the event the first rate of traffic is greater than the first threshold, marking, by the network device, the data packet with a second marker type; receiving, at the network device, a second data traffic flow having a second rate of traffic; combining, by the network device, the first data traffic flow and the second data traffic flow to produce a third data traffic flow; in the event the data packet is marked with the first marker type, forwarding, by the network device, the data packet in the third data flow; determining, by the network device, whether a third rate of traffic of the third data traffic flow is less than or equal to a second threshold; in the event the data packet is marked with the second marker type and the third rate of traffic is less than or equal to the second threshold: in the event the data packet is marked with the second marker type and the third rate of traffic is greater than the second threshold, discarding, by the network device, the data packet.
