set_capacities_random_power_law
(topology, capacities, capacity_unit='Mbps', alpha=1.1)[source]¶ Set random link capacities according to a power-law probability density function.
The probability that a capacity is assigned to a link is:
Where is the set of allowed capacity, i.e. the
capacities
argumentNote that this capacity assignment differs from
set_capacities_random_zipf
because, while in Zipf assignment the power law relationship is between the rank of a capacity and the probability of being assigned to a link, in this assignment, the power law is between the value of the capacity and the probability of being assigned to a link.Parameters: - topology : Topology
The topology to which link capacities will be set
- capacities : list
A list of all possible capacity values
- capacity_unit : str, optional
The unit in which capacity value is expressed (e.g. Mbps, Gbps etc..)
