Abstract: A method, an apparatus and/or a system to regulate yellow traffic in a network is provided. In one embodiment, the method includes quantifying, an extent of violation of a transmission rate of a data traffic relative to a committed bandwidth profile in a network. The data traffic is generated through a client device coupled to the network. The method also includes regulating, a volume of the data traffic associated with a particular level of compliance relative to the committed bandwidth profile, at an edge node of the network, based on the quantification. The committed bandwidth profile specifies an average rate of committed and excess data traffic generated by the client device. The particular level of compliance is characterized by the transmission rate exceeding a committed information rate and lying within a peak information rate. The peak information rate is maximum allowable rate of admission of frames into the network.

Abstract: In one embodiment, a network processor services a plurality of queues having data using weighted round robin scheduling. Each queue is assigned an initial weight based on the queue's priority. During each cycle, an updated weight is generated for each queue by adding the corresponding initial weight to a corresponding previously generated decremented weight. Further, each queue outputs as many packets as it can without exceeding its updated weight. As each packet gets transmitted, the updated weight is decremented based on the number of blocks in that packet. If, after those packets are transmitted, the decremented weight is still positive and the queue still has data, then one more packet is transmitted, no matter how many blocks are in the packet. When a decremented weight becomes negative, the weights of the remaining queues are increased to restore the priorities of the queues as set by the initial weights.
