A boost is provided in an overloaded system by distinguishing nodes with a 'bad' traffic history from nodes with a “good” traffic history. In so doing, a core network node is able to apply additional resources to the node(s) having a “good” history in the form of a boost factor. Based on a system capacity and a working point, e.g., a critical number of active nodes with a “bad” traffic history, the core network node may determine a throughput history limit belonging to the “bad” traffic history. Responsive to expected requirements for a newly active node (i.e., a node having a “good” traffic history), the core network node determines a boost factor for the newly active node, applies the boost factor to the average resources allocated to the nodes with the “bad” traffic history to determine boosted resources, and allocates the boosted resources to the newly active node.

Dimensioning granular multi-timescale fairness

To support quality of service fairness in a communication network, a network node determines a maximum bucket size, for a token bucket controlling a transmission rate from the network node over a transport line between a radio access network and a core network, based on a drop precedence and a given timescale.

Maximum bucket sizes for multiple timescales

Regulating transmission of data packets between a first network and a second network over a datalink. Embodiments include determining a first plurality of token bucket rate (TBR) parameters, each TBR parameter corresponding to a one of a first plurality of packet drop precedence (DP) levels and one of a first plurality of timescales (TS). The determination of the first plurality of bucket rate parameters is based on a peak rate requirement, the data link capacity, and a nominal speed requirement associated with the data link. Embodiments also include determining a second plurality of TBR parameters based on the first plurality of TBR parameters and a guaranteed rate requirement, the second plurality comprising a further DP level than the first plurality. Embodiments also include regulating data packets sent between the first network and the second network via the data link based on the second plurality of TBR parameters.
