Network Modeling and Simulation
As the mobile network is evolving, there are several efforts to improve the overall performance of the network. One of the key initiative is to implement multi-access edge computing (MEC) architecture to enable ultra-low latency in communication. This MEC architecture have certain advantages over current centralized cloud computing (CCC) architecture, but has critical latency issue when ther is regional communication traffic spike. To address this problem, we proposed a new hybrid cloud computing (HCC) architecture. All three mentioned architectures are shown below.
In order to assess advantages and disadvantages of each architecture, we constructed a discrete-event simulation model that can simulate all three networks. Figure below shows the overall diagram of the network simulation model, including interface, simulation, and analysis module.
Using the simulation model, each network's response to traffic spike was simulated and assessed. Results, plotted in the figure below, shows that the HCC architecture can perform well under the specified latency tolerance limit for most of the time, which shows promise as the candidate for the final architecture.
