Average packet delay in Dual‐Mode EEE: An analytical model

Abstract

An analytical model is developed for the average packet delay for Dual-Mode Energy Efficient Ethernet to complement the power consumption model for Dual-Mode EEE developed previously. The model can be used for determining the tradeoff between power reduction and performance degradation caused by utilising the method. The analytical mode's results closely match the results from simulation.

“…Similarly, Fig. 5 confirms that the errors of D f and η f in (25) and (26) when λ is small can be suppressed by the weights Pr{ξ = 1} and Pr{ζ = 1}. Therefore, as we will verify by simulations in Section IV, the analytical results of (31), (32), and (33) are quite accurate.…”

“…Similarly, Ref. [15], [24], [25] did not notice the feature of the dual-mode strategy, and thus cannot find the closed-form mean delay for the dual-mode strategy in the general case. This indicates that simply extending the models of the single-mode strategy for the dual-mode strategy is not feasible.…”

“…Currently, a few works [15], [24], [25] applied the analytical models developed for single-mode strategies to study the dual-mode strategy. Based on the model in [26] and [27], Ref.…”

“…Based on the model in [26] and [27], Ref. [24] and [25] analyzed the dual-mode strategy with N f = N = 1, where the interface wakes up immediately as soon as a frame arrives. However, such a strategy has quite low power efficiency and is not suitable for practical applications [11], [12], since the vacation time is short and a large amount of energy is wasted by Wakeup operations.…”

“…Substituting (17), (18), (25), (26), and (27) through (30) into (3) and (4), we obtain the mean delay and power efficiency of the dual-mode strategy:…”
