| Abstract(in English) | With the diversification of mobile applications, network slicing, which allocates appropriate resources according to the application, has been proposed to improve the user experience and achieve the diversification of network services. However, in a wireless environment with fluctuating link capacity, we need to adjust each slice’s bandwidth dynamically while maintaining the user experience when we can not satisfy the requirements specified by each application due to insufficient link capacity. In addition, since we need to allocate bandwidth for the clients who do not use slicing, network operators need to assign the bandwidth based on a clear metric. We propose a novel control method that sets a utility function, called slice quality, for each slice and adjusts each slice’s bandwidth depending on the link capacity to keep these qualities fair. We set different utility functions for the normal slice, which requires a fixed amount of bandwidth, and the residual slice, which manages the rest of the system. We update the allocated bandwidth so that each slice’s quality is fair based on the link capacity at each point in time. We show a median improvement of 65% in the slice quality’s fairness than a simple bandwidth allocation policy while keeping the quality degradation of normal slices below 10%. |
