Abstract

In this paper, we have followed the idea of exploiting inter-technology load balancing leveraged by flow admission control with software defined networking (SDN). By means of the highly flexible interfaces, SDN is simply effective in the 5G network architecture where load balancing and dynamic flow admission control are considered as essence of networking. In one hand, load balancing presented in this paper reveals a drastic reduction of unsatisfied-user percentage almost by five times while, on the other hand, it enhances per-flow resource allocation more than %. In addition, this proposal substantially off-loads the core-network, avoids over-utilizing the cellular network and reserves resources based on cut-off priority. Explicitly, it allows a certain degree of freedom to choose the network options based on user-preference and their priorities. Finally, we compare our load balancing algorithm leveraged by flow admission control with an analytical model to ensure the correctness and efficiency.
