Expand description

Switching cost.

Fields

energy_cost: f64

Average cost per unit of energy.

phi_min: f64

Power consumed when idling.

phi_max: f64

Power consumed at full load.

epsilon: f64

Additional energy consumed by toggling a server on and off.

delta: f64

Required time in time slots for migrating connections or data.

tau: f64

Wear-and-tear costs of toggling a server.

rho: f64

Perceived risk associated with toggling a server.

Implementations

impl SwitchingCost

pub fn switching_cost(&self) -> N64

Computes switching cost for a server of some type.

pub fn normalized_switching_cost(&self, delta: f64) -> N64

Computes normalized switching cost for a server of some type given the time slot length $\delta$. Approximately, measures the minimum duration a server must be asleep to outweigh the switching cost. Referred to as $\xi$ in the paper.

pub fn from_normalized(
    delta: f64,
    normalized_switching_cost: f64,
    energy_cost: f64,
    phi_min: f64
) -> Self

Builds switching cost such that the normalized switching cost matches $normalized_switching_cost$. Here, $\delta$ is the time slot length.
